CFL Answered

Who else uses CFL ( Compact fluorecent Lightbulb) I my self replaced all my rooms light with them, so 4 bulbs in total. They sell them at Sams club, 8 CFL units that replace 60 watt bulbs for about $10. Instead of using 60 watts they only use 13, also they do not get as hot making your room cooler in the wee hours of the morning. Im not sure if they sell them for the smaller bulbs like the skinny ones ceiling fan, because thats the kind of bulbs we have on our wall. I decided not to use that light for now. Most of all the light bulbs in our house are fluorecent, except the bathrooms, a few lights we use rarely and the 3 different intensity bulbs. Who else uses CFL and if you don't, do you want to switch?


All the bulbs in my house are cfl's.have been since we bought the place six years ago. I don't have west's problem, I like a dark house and often we don't even turn on a light until after dark.

It rather pisses me off than brighter CFLs are so... lame. I mean, my reading light for a long time was one I made in 4H, and it had a 200W incandescent light in it. And I liked the 300W halogen torchier lamps. But you can't get 200W equivilents in CFL in convenient sizes. So the livingroom now has, um, THREE 65 watt fluorescent torchier lamps, plus an ott-light. To equal, more or less, the 2 300W halogen lamps I used to have. And they've got weird or multiple bulbs. And the ballasts are crappy and blow faster than the lamps. And you can't use them on dimmer or X10 circuits. And I've seen them fail in scary ways (sparks!) And if they break you get mercury contamination. And no one makes nice fixtures designed for CFL except Ikea. Grr. But I did especially enjoy replacing all those 40-60W candelabra base bulbs with CFL and circular fluorecent fixtures. The library used to have 1200W worth of those, and now it has about 100W of CFL (of course, I added about 1000W of computers...) The upstairs hallway went from 360W to about 60W... (They did the kitchen before I bough the house. 240W of 4foot tubes, plus under-cabinet fluorescents plus a few halogen spots. The redesign was done by a professional chef; I guess they like a lot of light!)

I use CFL and CCFL; I much prefer CCFL (cold cathode fluorescent) because they have no filaments to burn out, thus I don't have to waste any mercury. The life of CFL bulbs disappoints me greatly, since I have traffic-signal-incandescent bulbs (only) that have outlived them. I think many CFL "Ballasts" are often crappy also. Half of my CCFL's are made of scavenged "white neon" tubes. The other half are scavenged from junked flatbed scanners. I love good stuff that lasts almost forever. White LED clusters too.

Funny I had one in the front yard that lasted 10 years, it turns on at dusk and turns off at dawn.

Sure some CFL's are good, they are not all bad, except for a few bushels of them that my silly friend is storing in his garage. I think the ones with coil ballasts last longer than electronic ones. (Take an electronic one apart and see a weird complex circuit that blew) And yes, I'm talking about the CFL's that screw in like light bulbs do.

Let's see, the incandescents in our house are: Two up under a crawlspace that get smashed too frequently to put in an expensive CFL, one in the far corner n the basement that is turned on once a month, the dimmer lamp by my mom's bed, since we can't find dimmable CFLs near here, and a bizarre squid-like floor lamp that takes little tiny bulbs. Seems like a lot until you consider how many desk lights, reading lights, workspace lights, and overhead lights are in an average house.

Two notes: incandescents put out 10% of their energy as light and 90% as heat. Fluorescents are the opposite. These are actual figures, averaged and hen rounded from various sources.

Also, Kiteman: You can get dimmer-friendly CFLs, they just cost more, are slightly less amazingly efficient, and are kind of hard to find.

The main reason I switched to CFL in my room was because of the heat, the A/C doesn't turn on at night and I only have my ceiling fan. I'm at my desk so my laptop puts off alot of heat and then there was a incandescent lamp beating down on me. So I switched.

I'm changing ours as the TFs "blow", except, as Nacho says, for the lights on dimmers, and the weeny halogen bulbs in our Ikea standard lamp (which is actually the most-used light in the house).

Will they be producing a dimmer-friendly CFL, or will I have to buy new switches when TFs eventually disappear?

. I've read that CFLs for dimmers are available, but I've never seen any advertised. If someone finds a source, please let me know.

In every room in my house I use them, except my bedroom - that has a dimmer which blows them if I try to dim the bulbs. >.>


(I've got 5, but none of the fittings in my house will take them...)


Yea, sometimes it's just the shade that's just a bit too close, I have tried...

I love them. I made an Instructable on using them in your home. They are great.

We've largely changed over to the fluorescent bulbs, also. As you say, they aren't the best for bathrooms (wives don't dig the color balance for applying makeup.) They don't function well in closed fixtures, however. Seem to seriously limit the life of the bulb. @Kiteman: We also have the Ikea halogens, which can't use the CLFs. But I have seen LED replacements. Still expensive, but that's changing fast. The LED bulbs have amazing efficiency....

. I've changed all but the bulbs on dimmers to CFLs.

I changed the spelling, thanks firefoxs spell check doesn't work all the time. I know the light I use the most is on my wall but it only takes bulbs 1/2 in (1.25cm) across and I haven't seen any that size. I did ask my dad if we could get a diffrent fixture though but it would just be easier to change my habits to turn on one of my three desk lamps. Which happen to be 3 bulbs on a pole.
