Frequently Asked Questions

QUESTION:
Can I put a 100 Watt equivalent CFL bulb into a 60 W light socket?
I am thinking of changing my light bulbs to CFLs because the sockets in my room are rated only for 60 W, and its not enough light. If I wanted to buy a CFL bulb that was EQUIVALENT to say 100 W or 150W in terms of lumens but they are actually 23W and 34W respectively, they should be safe for my socket rated 60 watts right?
- ANSWER:
  Yes, a 100 watt equivalent cfl only take 26 watts. You could go even bigger (125 equivalent cfl in watts it is 39) if you want more light.
QUESTION:
If you have light socket rated for 60 watts can you safely use a 100 watt equivalent CF bulb in it?
I ask because a 100 Watt output Equivalent Compact Fluorescent only draws 23 Watts.
- ANSWER:
  You are correct. Since the CFL uses 23 watts of electricity, it can safely be used. The 100 watt number is the amount of light equivalent to an incandescent bulb, not the electricity used.
QUESTION:
Can I use a 26 watt (100 watt equivalent bulb) in a 60 watt max socket?
I bought a stained glass lamp and not giving any thought installed 2 100 watt bulbs in it. About 6 months down the line the top melted and the lamp fell apart.

I bought a new one and noticed it said that there is a 60 watt maximum in each socket. There, I figured, lie in the problem with the first time I bought the lamp... that it wasn't designed for 100 watts, only 60.

Today I saw energy saver light bulbs that say they are only 26 watts or something like that, and yet a "100 watt" equivalent....

so does that mean I can use them on a 60 watt maximum lamp socket?
- ANSWER:
  There are two possible reasons to limit the lamp to 60 watt bulbs. 1. the heat of a higher watt bulb is to hot for the lamp. 2. the circuit in the lamp is only designed for the electrical power to run a 60 watt bulb.
  For both cases it is safe to use a CFL bulb rated at 26 watts and equivalent to 100 watt bulb in light output.
QUESTION:
Can you put a energy smart light bulb(26 watt equivalent to 100 watt) in a 60 watt socket?
- ANSWER:
  Of course. old incan bulbs state the energy used as "60 Watts", while new twist bulbs state the energy used (26 watts) and the light equivalent, 100 watts.
QUESTION:
100 Watt Equivalent CFL is it 26 Watt or 27 Watt?
I read some other posts in here saying that, if the fixture is rated for a 60 watt traditional bulb, then it would not matter if a person used a 26 watt CFL, which is about a 100 watt traditional bulb equivalent. I just bought a light fixture that says on the outside of the box, use with 100 watt or CFL equivalent bulb. Upon installing it, the little sticker on the socket for the bulb says, use a 100 watt max or 26 watt max CFL bulb. If it will tolerate a 100 watt max traditional bulb, why make the CFL distinction? And, the CFL 100 watt traditional equivalent bulbs I bought are 27 watt bulbs - is there a concern with having gone 1 watt over the max? If a 100 watt max is the max, then why should it matter the wattage of the CFL bulb, as long as it is less than 100 watts?
- ANSWER:
  The rating of the CFL in relation to the equivalent incandescent bulb is related to the efficiency of the bulb. Most 100 watt equivalents are 26 watt, but I could easily see the need for 27 watts. This doesn't necessarily mean the bulb is of a lesser quality, it could just be that a bit more wattage is required to create the color of light the bulb uses.
  
  I have not seen a fixture that gives a different rating for a CFL, but there is a valid reason for such a rating. The limiting issue for a household fixture is not the size of the wire or other conductive parts of the fixture, but rather the amount of heat the no-conductive parts can handle. The CFL will put out less heat than the incandescent, but the heat is focused in a different area. With a standard bulb, most of the heat is generated in the filament, which is away from the base of the fixture a bit. A CFL produces most of its heat in the electronic ballast which is in the plastic case at the base of the bulb. I would guess that the fixture you have is capable of dealing with heat a couple of inches from the base, but not so much right at the base.
  
  The difference in heat output at 27 watts vs 26 watts is nominal. I would not have an issue with the 27 watt bulb in a 26 watt fixture, but it would void your warranty and limit the liability of the manufacturer if there was a problem. CFLs have some safety features to reduce the risk of fire, so I would think worse case you may damage the fixture but I would not consider this likely at 1 watt over rated capacity.
QUESTION:
Fixture calls for max 60 watt bulb but can I use 23 watt CFL that is equivalent to 100 watts?
If the max watts for a light fixture is 60 watts, can I use a 23 watt CFL even though it is the equivalent to 100 watt incandecent bulb?
- ANSWER:
  Yes you can. If it fits. The heat from one of these types of bulbs is far less than a regular incandecent.
QUESTION:
Can a 26 Watt (100W Equivalent) bulb be used in a 65 watt recessed light fixture?
Do the recessed light fixtures go by temperature or do they go by actual wattage of the bulb? I just want to make sure that it would be safe to put a 26 watt bulb that produces 100 watts into a 65 watt fixture. Thanks!
- ANSWER:
  Maybe.
  
  The 100W rating is to prevent overheating of the fixture and its wiring. The 26 watt bulb will not overheat the fixture.
  
  The bulb will work but it may overheat. CFL bulbs create heat which needs to be dispersed. Some bulbs state not to use in enclosed fixtures. In a recessed fixture the heat buildup may be excessive and lead to premature failure of the bulb.
  
  Check the package for details.
QUESTION:
Can 23W CFI bulbs that are 100W EQUIVALENT be safely used in lamps intended for max. 60W bulbs?
If a lamp or light fixture is labeled "Use maximum 60 watt bulb", is it safe to use a compact florescent bulb that is the EQUIVALENT of 100 watts but only uses 23 watts? I've heard contradictory information about this. When a CFL bulb is labeled "100 watt equivalent", I don't know if it refers only to the amount of electricity it uses or to the amount of heat as well.
- ANSWER:
  Hi
  the reason some fixtures say this is purely because of the heat that a bulb produces so there is reason that i can see like yourself why you should not use one of these modern compact florescent bulbs.
  the only person who might object to using these things is a radio amateur as they put out a lot of noise which makes operating the radio almost impossible.
QUESTION:
How many 24 watt fluorescent light bulbs can I run on 14-2 wire?
the little enersy saver bulbs are bright but not enough for a production. the box says 24 watts equivalent to 100 watts tungsten i want to run 10 together would it work?
- ANSWER:
  14-2 wire is rated for 15 Amps, right? For a 110 Volt circuit, that's 55 * 15 = 1650 Watts. You're only running 10 bulbs, so that's 240 Watts. You should be fine.
QUESTION:
Can I use a 100 watt bulb in a 75 watt fixture?
I know enough not to do this, but I have 6 old (7 years old), but brand new 100 watt old-style bulbs which I would like to use in a dimmable light fixture, always keeping the bulb slightly dimmed. Would these bulbs be using less wattage while dimmed or are they still a fire hazard? A new dimmable spiral bulb equivalent to 75 watts costs more than plus tax! Thanks, Melita
- ANSWER:
  Yes, dimmed down they would be less than 100 watts. But it might still not be a great idea, since
  
  (1) I'm not sure how much dimmed they would need to be to be 75 watts. They might be only half as bright, and you might usually run them at more than 75 watts.
  
  (2) anyone who didn't know they were 100 watt bulbs, or who forgot, might run them for a while at full power.
  
  The spiral bulbs (compact fluorescent) would be much less than 100 watts for the equivalent brightness, so they'd be fine.
QUESTION:
Why aren't there any lamps now available that willl allow a 100-watt light bulb? All my old ones did.
I can't see well enough to read with a bulb less than 100 watts. And no, a 26-watt fluorescent bulb is NOT equivalent - and they won't fit in a lot of lamps. With so many older people who need more light to see, it's important to have lamps that will take higher-wattage bulbs.
- ANSWER:
  its possibly a few reasons. the energy used vs the new screw in flourecents . do they even make100 watt bulbs anymore? Or they stopped making lamps that take 100 watt bulbs any of those reasons could be it . I would ask the manufacturers online for the reason
QUESTION:
Can the new CFL bulbs be used in any type of light recepticle?
I've changed out most of my light fixtures with cfl light bulbs. If a recepticle states use no more than 40 watts can you use a 26 watt cfl with a 100 watt equivalent to a regular light bulb in these lamps/recepticles?
- ANSWER:
  Yes.
  The label shows the maximum wattage bulb that you can use in the socket. This is because of the heat generated by a conventional tungsten bulb.
  
  A cfl bulb carries two figures: actual wattage and tungsten equivalent wattage (which gives an indication of the equivalent light output). The heat generated is due to the actual wattage, not the equivalent power.
  
  Therefore you can safely use a cfl lamp of up to 40W in a receptacle labelled 40W max. Note that this bulb will provide light output approximately equivalent to a old fashioned 200W bulb. Which is a lot!
  That's why most cfl bulbs have a power of 25 W (equivalent light output of a 100W tungsten bulb) but only the heat output of a 25W bulb.
QUESTION:
Help with understanding energy efficient light bulbs?
Hello this is problably a silly question but I am understanding electricity and wattage challenged, LOL. I purchased a CFL (compact fluorescent light) energy efficient 23 watt daylight 5000k, 100 watt incandescent equivalent bulb. I want to use this bulb in a desk lamp which accepts only 60 watt or less incandescent bulbs. So can I use the CFL in my desk lamp? Do I go by the fact the bulb is 23 watts or that it is equivalent to a 100 watt incandescent bulb which makes it unsafe to use in my 60 watt incandescent bulb maximum desk lamp. Thanks for taking the time read and help this electrically and wattage challenged woman LOL.
- ANSWER:
  I'm no electrician but the 23 watt should work fine in a 60 watt lamp.
  
  For years in my kitchen I kept putting a too-high-wattage bulb in a fixture that apparently couldn't take that much incandescent. I put in a much lower wattage CFL, which has never burnt out. I can see!
QUESTION:
Why not just use “Appliance” light bulbs to bypass the 2012 ban on incandescent light bulbs?
Has anyone else thought about using the smaller 60 Watt appliance light bulbs to effectively bypass the upcoming ban on sale of ordinary 60 Watt incandescent light bulbs?

Next year 2012 the government will make it illegal for stores to sell regular incandescent light bulbs, however, due to the high levels of heat in a stove, and the low temperatures in a fridge, stores will still be allowed to sell the smaller 40 W and even 60 W versions of the old style incandescent bulbs, labeled as "appliance bulbs". I know, those old bulbs waste so much in heat, but some people are just stuck on them and refuse to use anything else, so did anyone else just figure it out, that the solution to bypass this ban is to just use the “Appliance” bulbs instead ? They are smaller, yes, but the 60W versions give out the same light as the regular 60W light bulbs, so who cares.

By the way, I sort of hate compact fluorescents but I use 100 Watt - equivalent compact fluorescents in the hallway lights because I wanted brighter lights than the enclosed housings of those lights would allow, the encloses said that only a 60 W bulb was allowed otherwise fire could result do to heat buildup. Yes, that is true, those thing get really hot, so instead of using a 100 W ordinary bulb and burning down the house, I switched over to a similar-output compact florescent bulbs for those fixtures only. Otherwise, I’m using much hotter 100 W halogens (and some 60 W halogens) in every other lamp in my house.

I did a test in my living room light that has 3 sockets: I placed a 60 W incandescent, a 60 W halogen, and a 100 W incandescent bulb into the sockets. I would slightly unscrew one bulb at a time to turn it off separate from the others. I found that the 60 W halogen ( bought at Home Depot ) gave about the same amount of light as the 100 W incandescent bulb, while the old 60 W incandescent was definitely a lot dimmer ! So from that one small test I see that by using the halogens instead of incandescent bulbs I’m getting the same light for a little bit less energy, and that’s good enough for me.
CFL lamps also give off lots of UV radiation, something that most people don't know about. A while ago I bought 2 table lamps from IKEA. I used ordinary light bulbs in them for about 2 years. Then one bulb burned out and I replaced it with a CFL bulb. Well, about a year later that bulb burned out. The other lamp still had the old incandescent light bulb still working after 3 years! I decided to replace both with a newer cool-white CFL type of bulb. Well was I surprised !!!! The lamp shade that had the CFL in it was totally destroyed, the 1-mm thick plastic liner inside that lamp shade was all cracked and when i touched it the thing just fell apart in my hands ! meanwhile the lamp shade that had used the regular light bulb was just fine! So I had to buy a new lamp shade for both lamps. Seems that the CFL lamps really beam out a ton of Ultra-Violet light, something not good for reading lamps where eyes are close to such dangerous rays !
Just GOOGLE this fact and see for your
- ANSWER:
  Probably the biggest reason that appliance bulbs will not work to get around this piece of legislation is because they are ALSO of incandescent construction . . . .
  
  CFLs are kind of a stop-gap solution to a questionable problem. LEDs make more sense, despite the extra upfront costs. LEDs don't give off heat, do not contain mercury (CFLs do), and last anywhere from 12 to 20 years.
  
  Makes you think, doesn't it?
QUESTION:
What CFL bulb mimics the color of incandescent bulbs. I dont want that white white white light look ?
I want to change over to cfl bulbs, but do not like the white light that CFLs come with. I want a nice warm yellow look that an incandescent provides. I will be purchasing 60 watt and 100 watt equivalents.
- ANSWER:
  Get the ones that have a "warm" color instead of "cool white". You can hardly tell the difference between the light from an incandescent bulb and a "warm" fluorescent bulb.
QUESTION:
Does anyone know of a 100 watt CFL that is truly compact.?
My kitchen lighting fixture is designed to hold 2 60 watt incandescent bulbs. The corresponding CFLs are not as bright even though labeled 60 watt equivalent. The normal 100 watt CFLs do not fit. Are there any 100 watt that are the size of a 60 watt?

ℬ ℋ
- ANSWER:
  You don't mean a 100 watt CFL. You mean a CFL that gives equivalent light to a 100 watt incandescent. That would be about a 23 watt CFL. I have some made by Philips, called a "mini-twister". They're smaller than most CFLS of that wattage. I got them at Home Depot. I had the same problem of regular size CFLs not fitting in the ceiling fixtures.
QUESTION:
Would two 23 watt EarthBulbs support coral life?
The light bulbs are 23-watt CFL equivalent to standard 100-watt incandescent bulb, 1600 lumens

Is 2 of these enough for coral to live off of in a 10 gallon tank?
- ANSWER:
  I don't think so. you need to have a broad spectrum of light. to have corals you are going to need at least a 50/50 bulb.
  
  visit this sites forum and go to the equipment section, there is a post about aquarium lighting, that should help you with this question.
QUESTION:
Can you put a higher watt equiv. florescent bulb (cfl) in a light fixture?
Lets say you have a light fixture that is only rated for 60 watts. A 13 watt florescent bulb (cfl) puts out the same light as a 60 watt incadescent bulb. Could you put a 26 watt cfl, which would be equivalent to a 100 watt incadescent, in that fixture? What about a 55 watt cfl, which would be equivalent to a 250-300 watt incadescent bulb?

In other words, does only the wattage matter when determining if a bulb is right for a fixture?
- ANSWER:
  When a fixture is rated for a certain wattage, that means that the wiring can handle drawing that much power safely and the amount of heat generated by an incandescent bulb running at that wattage won't damage the fixture or start a fire. Heat really isn't much of a problem with CFLs, so you can ignore that concern. However, it still isn't a good idea to install a CFL with a real wattage above the rating for the fixture because of the wiring concerns.

- ANSWER:
  Links are really no good, but i know exactly what you are talking about. And yes those bulbs are dangerous for bearded dragons.
  
  The coil bulbs, put out little to know uvb at all and have been known to cause eye damage and cause photoconjunctivitis. .It inflames the eyes, can damage both the eyes and skin. The compact/coil bulbs are notorious for causing this.
  
  As for the infra red bulbs, they are no good for dirunal reptiles (up during day), they were made for nocturnal reptiles and can cause a unhealthy strain on the eyes..
  
  No coiled or red bulbs!
  
  Do your self and bearded dragon a favor and get a Mercury vapor bulb, they give off UVB/UVA and heat all in one, last for 6months and are really great depending on the brand you buy, i personally use Power suns by zoo med and i am very happy. Since i started using these my reptiles colors and activity have been amazing.
  
  http://www.petmountain.com/product/reptile-incandescent-bulbs/11442-107801/zoo-med-powersun-uv-mercury-vapor-uvb-lamp.html
  
  A 100watt would be good for you. Just make sure to get a proper size dome fixture with a good wattage, much like the zoo med deep dome fixture, a lot of people make the mistake of buying these bulbs and try to put them in a small wattage fixture like one rated for 75w, then the bulb blows out and they claim it the company problem, this happens all to much, if you want the bulb to work to its full potential get the right fixture..
  
  Sorry for the rant... Good luck!
QUESTION:
High watt equivalent compact flourescent...?
Are there any good-quality 150watt-plus equivalent compact flourescent light bulbs on the market. I've seen a lot of 100 watt and less but they seem too dim to me.
- ANSWER:
  While a regular (incandescent) light bulb uses heat to produce light, a fluorescent bulb creates light using an entirely different method that is far more energy-efficient — in fact, 4-6 times more efficient. This means that you can buy a 15-watt compact fluorescent bulb that produces the same amount of light as a 60-watt regular incandescent bulb.
  
  Don't worry about the math, though — this should make it easy for you to figure out which compact fluorescent bulb to buy by displaying the equivalent regular watts you're used to prominently on the package. Just look for the wattage you would normally buy in a regular bulb.
  
  In case you're curious, here are the watts needed by regular incandescent bulbs and compact fluorescent bulbs to produce the same amount of light.
  
  60 watts incandescent = 15 watts compact fluorescent
  75 watts incandescent = 20 watts compact fluorescent
  100 incandescent = 26-29 watts compact fluorescent
  150 incandescent = 38-42 watts compact fluorescent
  250-300 incandescent = 55 watts compact fluorescent
QUESTION:
What happens to the light bulb?
what happens if you put a 26 watt efficient light bulb that is equivalent to 100 watts into a 60 watt lamp?
- ANSWER:
  It's perfectly safe.
  
  The 60 Watt rating for the lamp is the amount of power the fixture can dissipate without overheating. You are asking it to dissipate only 26 Watts.
  
  The "100 Watt equivalent" statement on the package is saying that this bulb will emit about the same amount of light as a 100 Watt incandescent bulb (but only needs 26 Watts to do it). It's not talking about actual power (heat) output.
QUESTION:
If a lighting appliance (like a table lamp) says maximum 60 Watt bulb, can I use a low energy bulb of 20 watt?
The wattage is only 20 though the light given out is equivalent of 100 watts. So, would that be said to exceed the recommended wattage?
- ANSWER:
  Its fine to use the 20watt LE lamp. The rating is to protect the fitting and shade from heat.
  
  A LE lamp produces less heat and less current.
  
  It would not be true that you coud use a 60 watt low energy bulb ( if they existed ) so its not right you can use 60 watts in any format.
  
  A LE lamp uses les energy than a filiment lamp but more than the SAME wattage rating. EG a 60 LE lamp would produce far more heat than a 60 watt filiment lamp because they are less heat, but more light, efficient.
  
  EG we normally compare 20 watt to 60 watt. If you had a 60 watt LE then it would melt/fire the shade - it would prduce far too much heat and light.
QUESTION:
can i use a 23w cfl bulb with 100w output in a 60w fixture?
I have a 23 watt energy saving bulb that has an equivalent of a 100 watt bulb. Can I put that in a light fixture with a 60 watt max?
- ANSWER:
  Yes you can. The equivalent light output is 100 watt, but the bulb is only a 23 watt so no problem using it in that fixture.
QUESTION:
Energy Efficient Light bulbs question about Watts?
I'm replacing a light bulb, my socket says 60watts max, I have an energy efficient bulb that says it's 26watts, but that's equivalent to 100. should I be paying attention to the watts or the equivalent?
- ANSWER:
  The reason there's a maximum rating for the socket is that they don't want the the socket to melt from the heat produced from the lamp - which is measured by the watts. High-efficiency bulbs get about 4x the light for the same amount of heat.
QUESTION:
Energy saving bulbs safety?
Is it safe to install an energy saving bulb(which uses 23 watts & produces light that is equivalent to a 100 watt conventional bulb) in lighting fixture that calls for a maximum wattage of 60?
- ANSWER:
  Absolutely. A regular bulb makes light by putting out heat-- hence the max wattage ratings for fixtures. The higher the wattage, the more heat, so always heed those ratings for regular light bulbs to avoid the danger of fire from heat buildup. CFRs (compact flourescent lights) produce light differently, and generate much less heat. I had a display of both types of lights at trade shows a few years back, with digital heat sensors placed near the bulbs. The CFL was only slightly hotter than the ambient room temp, while the regular incadescent was of course, HOT. The ballast in the CFL will heat somewhat, but usually does not get too hot to touch. I just installed two of the 23 watt bulbs in my new hall light, where before I had 5 of the 25 watt bulbs-- lots brighter, and using only 46 watts as compared to 125! Go for it!
  
  CFLs are also great for recessed light fixtures where heat build up is a serious concern.
QUESTION:
what's the best brand for CFL Bulbs?
I'm looking for 100 Watt equivalents, and the one I bought at Best Buy today was a total joke. I have one of those 75 Watt equivalent, glass enclosed CFL bulbs that lights up the room better than that one did when I put in. I'm looking for a 100 watt equivalent and would like to know if anyone knows a good brand I could use.
- ANSWER:
  Buy one of the big name brands, like Philips or Sylvania. The Philps ones I got seem to be good. But CFL bulbs are still a bit of a gamble in terms of exactly what light they'll produce. It's hard to tell until you light one up.
QUESTION:
All the new light fixtures in stores are too dim. What do i do?
I'm trying to buy light fixtures (lamps, celing fan with light, etc) that can handle the equivalent of 300 watts incondescent. I need a bright light in my living room. All the lights in the stores are like 13 or 14 watt cfl's that even if you put in 4 are still too dim. My last ceiling fan from the 90's could handle three 100 watt light bulbs and would light up the whole room. And you could read in that room. I have a new ceiling fan with a white bowl globe that only handles two 14 watt cfl's! That is the equivalent of two 60 watt light bulbs. You can sit below the celing fan light at a table and it is still too dim. Now I have a ceiling fan light and a torch light in the living room trying to lighten it up to read and it is still too dim. And all the lights in the stores say only 13 watt cfl's or 23 watt cfl's (which still dont seem as bright as a 100 watt bulb) Home Depot and Lowes say you arent supposed to put a higher cfl in it if it doesnt say that you can. So what is a person to do? Get more lamps? I already got two lamps with a total of 5 cfl's going, and yet it isnt bright enough to read in the room! What is a person supposed to do?
- ANSWER:
  Look for fixtures that use halogen bulbs.
  
  Halogen bulbs are quite bright, much brighter than CFLs. I think they will satisfy your needs.
QUESTION:
Is it safe to use a cover on a light bulb?
Hello, I just bought a 3-pack of energy efficient (GE) light bulbs. The ceiling has covers for the light bulbs. Is it safe to cover energy efficient light bulbs? The light bulb ends up very close to the glass after I screw it back on. Will it over heat?

Light bulb I speak of:
http://www.amazon.com/15517-26-Watt-100-Watt-Equivalent-Energy/dp/B00077MIKG/ref=pd_bbs_sr_3?ie=UTF8&s=hi&qid=1233527515&sr=8-3

Cover I speak of (similar):
http://www.trinacriacoffeesystem.com/images/light_bulb_cover.jpg

Thanks i advanced.
- ANSWER:
  Yes, it's fine. The cover is thick glass and can handle the (relatively) low levels of heat given off by the light bulb.

QUESTION:
Will this bulb give off UVB rays?
I have a Meijer-brand fluorescent light bulb (23 Watts; 100 Watt Incandescent equivalent). I've been trying to get a bulb, and sites I found for reptiles offer very similar bulbs. Are they the same? Can different fluorescent bulbs offer different rays? I have several fluorescent 23 watt bulbs, but I need UVB rays for my tortoise.
The meijer brand bulb doesn't say UVB, so are there actually specific bulbs for UVB rays, and some that don't?
Thank you Dave. Very insightful. I've been seeing the UVB levels on the bulbs offered on reptile supply websites, so I had my doubts about the bulb I own. Thanks again.
- ANSWER:
  I've never heard of it, so I would guess no. Any bulb that produces UVB will say so on the label, along with some type of rating with exactly how much UVB it gives off, 10.0, 10%, or something like that.
  
  If your looking for a UVB florescent tube, I would recommend either a reptisun, or one of the bulls made by arcadia. You need to know the strength of UVB you need, both companies make bulbs of varying uv output. Here's one site that has most available UVB bulbs. You may be able to find better process of you look around.

QUESTION:
Range hood install?
Hi everyone,I just completed an diy rangehood.I wired
it to a gfci receptacle that was 2 feet on the wall away.
I used 12-2 romex.The range requires a charcoal filter
or performance ring for the blower ring which I have not gotten yet.I connected the wiring to the extra empty
screws.It runs fine but there is 1 problem.The range
requires par20 50 watt halogen.I hade fluorescent spirals
rated about 12 watts and the equivalent of 100 watt light
bulbs and when I put them in they smelled as if they were burning.I have it all wired right.does anyone know if
the rangehood is halogen specific and can not use
fluorescent? Or could it be defective range or
need a separate circuit? Thanks for any advice
I thank everyone of you for helping and for advice.Turns out as stated,the fluorescent bulbs were not appropiate for my rangehood.I installed the par20 halogen and
that was the remedy... thanks
- ANSWER:
  You need the halogen bulb. if it calls for a halogen then you will burn up any other bulb that you put in it, it might blow up or shatter all over the place and possiably cause a fire. if you look at a halogen bulb and a regular bulb you will see the diffrence, the glass is much thicker in a halogen bulb than it is in a regular bulb.
QUESTION:
Best inexpensive portable power to run 1 or 2 clamp-on trouble lights for craft booth?
I need lighting for my craft booth at evening shows when the lighting in the area is dim or non-existent. I can't use a gas-operated generator. I know I can use a deep-cycle marine battery and an inverter (instructions on web) but I don't know what size inverter to use for a 12v battery if I want to run two 60 to 100 watt bulbs - or whatever the CFL equivalent is for brightness. The lights will have to be on for about 4-6 hours each use.

Can someone help me figure out if this is feasible? I need either one 100 watt light or two of something weaker. My math skills suck, I just want to know what to buy to make this work. Thanks you in advance!!!

QUESTION:
Why are multi-way lamp adapters not available in the UK?
In the UK we used to have adapters that would fit into a standard bayonet lampholder and allow the use of two or three bulbs. Now that the highest output compact fluorescent bulbs have only a 100 watt equivalent light output, such adapters would be very useful where more light is needed - but so far as I can see they are no longer available in the UK.

I managed to buy two-way Edison Screw adapters when I was in Canada, but of course these require a bayonet to ES adaptor at the input end and an ES to bayonet adaptor at the lamp end - an expensive and inelegant bodge.

So my questions are:

1. Why are the bayonet adapters no longer made whereas Edison Screw ones are (although not in the UK)? Apart from the lack of electrical polarity of the bayonet lampholder I can see no difference that would matter (bearing in mind that lamps are not polarised).

2. Does anyone have a better solution than the one I have arrived at?
In response to Girlie Electrics let me say firstly, many thanks for your response. However:

1. I already have an installation with two ceiling lamps and don't really want to add more.

2. Insofar as efficiency of lighting is concerned, although ceiling lights are not very pretty they are the most efficient way of lighting. Compare the light from the sun at midday with that in the evening.

3. 100 watt is more than adequate for a couple of CF lamps - indeed such lampholders could take up to 5 in the UK since each is only 20 watt.

4. Insofar as the numpties plugging in too many (more than 5?) how come this isn't a problem in Canada, bearing in mind that the currents there are twice as high with only a 110 volt line? Are the British really that much more stupid than the Americans and Canadians? And how come we weren't that stupid 25 years ago when multi-way adapters were readily available in the UK?
Many thanks, electric Les. You have confirmed my suspicions. But of course, apart from the polarity issue, exactly the same problems must apply to ES fittings, still readily available in the USA and Canada - carrying twice the current!

But of course, as we know, the UK wiring regulations are at one and the same time the first and the most stringent in the world.
- ANSWER:
  These two way adapters, often called Bijou adapters, as well as ordinary BC adapters were discontinued in the UK many years ago for safety reasons. They were often used, owing to the lack of plug sockets in older installations, not only for lighting but for supplying a radio set, electric iron or a vacuum cleaner. Polarity, lack of an earth, mechanical strain, poor contact and dangling cables could be a problem, as well as the hassle of connecting the appliance to them. As a BC lampholder is rated for 1 amp max and the old 14/0076 pendant flex rated for 2 Amp max, overloading and burnout of them was a common problem.
  Hope this helps.
QUESTION:
another question about growing cannabis?
again i dont know anything about this stuff and im learning as i go so dont make fun of how stupid i might sound...

if i were to grow indoors using fluorescent light bulbs...equivalent to 100 or 150 watts would i need to buy a lamp too? i only have a little desk lamp at my disposal...would that work or do i need to buy a new lamp?
- ANSWER:
  It all depends on how much you're growing. You need about 50 watts per cubed foot.
  
  for example, a space that is 2 ft by 2 ft and 3 ft high, that's 2x2x3 = 12 cubed feet x 50 watts = 600 watts.
  
  That's optimal wattage, so anything less will work.. just not as well.
QUESTION:
How do you get decent low-energy illumination?
Here in New Zealand, low-energy compact fluorescent light bulbs are bloody pathetic. The brightest one on the market consumes 20 watts and gives the equivalent brightness of a 100 watt incandescent bulb. The only room in our house where you can read in comfort has a chandelier with five of them. What can be done about this problem at a reasonable cost? Why can't you buy compact fluorescent lights with a reasonable light output? In this country power supply is 230 volts, and light bulbs have a bayonet fitting. Are usable low power bulbs available anywhere in the world? Even our local electrician can't give me an answer.
- ANSWER:
  Have you tried importing some? There are some really great fluorescent light bulbs with a 60 watt usage but a 1000 lumens output. I've seen one at a local store for .I've looked for some of the 60 watt cfls, but I haven't found any, but if you really need the right kind of light bulb and can't find any at your nearest store, you should order some online!
QUESTION:
question about aquarium lighting?
when lighting a planted aquarium they say you need 2-4 watts a gallon how does that apply to fluorescent and l.e.d. lights when they say there 40 watts but are equivalent to 100 watt incandescent bulb do you go by the incandescent wattage or the fluorescent wattage? is this an antiquated system for gaging lighting needs or is this 2-4 watt per gallon estimate figured for fluorescent?
so fish lover i'm trying to decide whether to get a 4 54 watt t-5 fixture or a 4 65watt power cfl fixture your recomendation and why?
i understand not being able to use incandecesents just useing it as an example
- ANSWER:
  You can not use incandescent lights for planted tanks. This rule is some watt out dated a little it applies only to T-12 bulbs, and T-8 bulbs. And only fluorescent may be used, 2-4 watts is good for medium light plants. You could only have 1 watt per gallon, or 1.5 watt for low-light plants. What I said before about that rule being out dated, is because when you use other things like T-5, and the all to expensive T-2, you don't need as much.
QUESTION:
Which number should I use when determining safe wattage in CFL Bulbs?
I'm about to be moving into a new apartment and I already know I want to replace all of the bulbs with CFL bulbs. However, I need strong lighting in at least two areas, one of which will have to be lit by a simple lamp.

I know most lamps have wattage limits on them for regular light bulbs, which is typically 60W or 100W. How does this apply to a CFL bulb? Should I go with the actual wattage of the bulb (42W) or the wattage of what it's equivalent to in a normal bulb (150W)?

I know the wattage itself actually determines how much power the bulb draws, and the lumens determines how bright the bulb is. But which is more important on these lamps that have wattage limits? Are they actually limiting wattage because of the power the lamp was designed to hold, or the lumens because of the heat factor?

Should I really look for a lamp that can hold 150W bulbs, or is a 60 or 100 Watt lamp okay with a 42W CFL bulb?
- ANSWER:
  use the wattage of the cfl which is lower & safer/cooler
QUESTION:
circuits and magnetism help?
1. These questions assume that you connect a number of light bulbs to a battery.
a. Will the bulbs give off more light if you connect them in series or in parallel?

b. You want the battery to last as long as possible. Will the bulbs connected in series or the bulbs connected in parallel run the battery down most rapidly?

2. You have connected a 16-ohm loudspeaker and an 8-ohm loudspeaker in parallel across the terminals of an amplifier. Assuming the speakers behave as resistors, calculate the equivalent resistance of the two speakers.

3. You have just received a gift of electric socks, which are popular in cold climates. They have a 90-ohm heating element that is powered by a 9-volt battery. How much current actually warms your feet?

4. Calculate the yearly cost of running a 5-W electric clock continuously in a location where electricity costs 10 cents per kW/h. Show all your work.

5. What is the relationship of magnetism to electricity?

6. From the information you gathered from Laboratory Exercise 2 in Lesson 7 using the parallel circuit similar to the one shown below, answer Questions 6a through 6c:

10. a. If 2625 nuclei decay from a sample of 2800 nuclei, how many half-lives have passed?

b. Is there a way to predict when a specific nucleus will "decay"? Explain your answer.
- ANSWER:
  9)There is not strict difference between elements.But i don't know the use of it so far.Better assume as used to be the elements and their isotopes.It is for chemical reaction that there are exist too with them.10)Once there is decay there is half life for simplest presenting.And in that decay not appear new elements.It is not nuclear reaction.For best pure reaction use the 100% elements in reactors because small bit of pollutions will stay very big not controlled substances.5) Electricity is moving energy,magnetism is bending space about any mass.So it is very different themes.There were works about them together simply.
QUESTION:
Should pot growers, and smokers be regulated by the new EPA guidelines for CO2 emissions?
http://www.npr.org/blogs/thetwo-way/2011/04/14/135415274/marijuana-not-so-green-study-finds-growing-pot-indoors-is-energy-intensive

A staff scientist at the Lawrence Berkeley National Laboratory studied the energy use of indoor marijuana growers and found it's an inefficient and energy intensive practice. Evan Mills, who undertook the study independently, reports that:

— "Cannabis production results in energy expenditures of billion each year."

— The electricity use is equivalent to that of two million average U.S. homes.

— It accounts for one percent of national electricity consumption.

To put it in more real-life terms, Mills writes that one joint "represents two pounds of CO2 emissions, an amount equal to running a 100-watt light bulb for 17 hours with average U.S. electricity."
- ANSWER:
  these numbers sound like BS to me... what are they doing that uses up so much electricity? 1 PERCENT OF THE NATION?

Algebra 2 homework please help due today?
I have been working on this problem for a hour and still can't figure it out. Its a function and I've never been real good at them. If you could help me ASAP i would really appreciate it because I have to have this done by midnight tonight. Thanks in advance. Here's the problem. ( We have to use a part to another question but number 60 is the one I need to solve)

59. Input incandescent wattage/Output wattage of CFL equivalent
25/5
60/15
100/25

60. Use the graph from Exercise 59 to estimate the wattage of a CFL bulb that creates light equivalent to a 40-watt incandescent bulb. Then predict the wattage of a CFL bulb that creates light equivalent to a 150 –watt incandescent bulb.
- ANSWER:
  Have you drawn the graph? Plot incandescent wattage against output wattage & you should get a straight line graph. You can then read off the two answers you need. (incandescent on x-axis, CFL on y-axis)
  
  The answers you get should be about 8w and 40w
QUESTION:
Incandescent lamps in the hand v. compact fluorescents in the bush...?
All right, this is a question that I've wondered about for a while but never devoted the brain cells to answering...

Say you already have a stockpile of incandescent lamps (i.e. light bulbs) in the basement. Is it more cost efficient in the long run to burn your current stockpile of incandescents or go out and purchase compact fluorescent lamps? (Assume that the fixtures in question are used less than two hours per day.)

Also, please answer as to winter usage v. summer usage. (Meaning, during winter a 100 watt incandescent lamp will help to heat your house more than the equivalent light output of a compact fluorescent), plus the electricity rate in winter tends to be lower than summer.

Thank you in advance for your well-thought-out and mathematically and engineering sound responses. Please also take into account future value v. present value of money. And no, this is not a homework problem. Only a mind as demented as mine could come up with this.
- ANSWER:
  Properly done, a furnace is a more efficient way of heating a space than an incandescent light bulb. So moving energy for heating from the light bulb to the furnace improves efficiency both of the lighting and the heating.
  Since you probably can't get your purchase cost back out of the incandescent bulbs [IBs], from an individuals view, it would be better to use them. But it should be possible to figure costs to make it rational and how much you would have to get for selling the bulbs.
  FCB's are available in a box of 6 from GE at Walmart for under right now, so call them each. "60 watt" FCB's use 13 watts and last about 10,000 hours. The already paid for 60 watt IBs last about 1000 hours (there are longer life versions, but they are dimmer and use more power) although both hour ratings are based on 8 hours on - the more time on each time turned on the longer a bulb lasts - turning on produces surge damage.
  Electricity in Texas currently costs about 13 cents a kWh. So a CFB uses 13 / 1000 * 10000 *.13 .90 in its life or .90 with purchase. Ten incandescents to run 10,000 hours use . So using the incandescents blows off .10 a socket and you could pay someone for each ten bulbs to haul them away and be ahead of the game and ANY money someone paid you would be a gain on your cash flow.
QUESTION:
A question about candle power?
We all know that light bulbs come in watts. 40, 60, 100 150 etc. etc. etc. Does anyone know the equivalent wattage from the light of 1 actual candle flame???? Please don't give me web links - they will be ignored.
- ANSWER:
  It's an interesting question and remember in college something similar to this. But, I think it's a little bit more complicated than 1 candlepower=1 watt.
  
  Candlepower would represent the amount of light while wattage would represent the amount of power required to product X amount of light.
  
  "Some light sources such as flashlights are rated in various different units, such as candlepower or watts. To be able to compare different types of light sources, it would be necessary to convert between these types of units.
  
  The short answer is, you cannot. Unless the manufacturer already has calculated both candlepower and watts, you're pretty much out of luck. You could try searching review sites in addition to the manufactures site, in hopes of finding the information already calculated.
  
  Different light sources could have the same power requirements, but vastly different light output. They are just not directly related enough.
  
  For example, searching Amazon.com I found descriptions of two different 12,000 candlepower flashlights. One was listed as 3 watt and another listed as 1 watt."
QUESTION:
Brightness of LED lamp?
Hi,

I was wondering what the equivalent output of an LED verses an incandescent light bulb is. For example, at work I use a 100 watt incandescent trouble light, I would like to switch to a LED trouble light that is cordless and puts out as much or more light. Out of all the LED trouble lights that I have looked at, the amount of LEDS vary from around 20 to 68 . None of them say how bright they are in comparison to an incandescent or a florescent light bulb which I find weird with all the ECO friendly marketing that has been going on lately.

Thanks

Carl

7.) Based on factors such as average cost of electricity in the U.S., energy usage per bulb, lifetime expectancy of each light bulb, and difference in price, DID YOU KNOW that you would save 54.23$ per 75 watt standard type a incandescent light bulb replaced by a compact fluorescent 20 W bulb that gives off the equivalent light?

a.) Yes

b.) No

8.) Will knowing this change your decision to switch to compact fluorescents next time you shop for light bulbs?

a.) Yes

b.) No

c.) I already knew this

9.) How do you believe the Bush Administration and the past Congress has performed with regards to curbing CO2 pollution?

a.) Irresponsibly

b.) Adequately

c.) Admirably

10.) Do you believe that climate change will have a negative affect on you in your lifetime?
