"Energy Efficient Light Bulbs" my butt cheeks !! silly things

[directhex]

yea they are energy efficient because they emit less light!?

i would buy them but only to feel less conscious about buying normal non EE bulbs. Not because the EE bulbs are a superior product...

they don't emit less light, they use less power. try placing your hand on an EE bumb for a few seconds. do the same with an incandescent.

worked out where the power difference comes from yet?

No, I'm far too busy peeling skin off the lightbulb

yes they use less power and emit less light. check it out get a 70w bulb use in a room for a week, then replace with a 70W EE bulb, you;re not going to tell me that the level of ambience supplied by the 2 to be 100% the same?

yes older bulbs are inefficient filaments and loose a lot of energy through heat but i have NEVER seen an EE bulb output the same amount of light as a standard bulb watt for watt...

We have one in our hall, it's not that bad actually. It does start off duller than a normal bulb, but it's still bright enough to be able to see fine.

You mean a 70Watt equivalent EE bulb... The EE bulb would only use about 13Watts(roughly) compared to the 70W of the normal bulb so there's a fair power saving there. I think the amount of light you get depends on the make you get. As I've said before I use GE bulbs and they're just as good as a filament bulb.

You mean watt for "incandescent-equivalent" watt, I presume, otherwise it wouldn't be a very good energy efficient bulb...

Simple solution - buy a higher wattage EE bulb if the manufacturers are going to exaggerate the incandescent wattage equivalent.

In general, you just multiply by 5, so a 20W energy efficient bulb should be the same as a 100 watt incandescent. Seems about right to me, anyway.

edit: beaten to it...

you're not comparing watt for watt.

try comparing a 20W incandescent with a 20W CFL (100W "equivalent"). oh look, the energy efficient bulb is eating the regular one for breakfast!

[Nickg]

yes but that is not how they are being sold by the manufacturers though, they are saying, "this is a 70w equivalent EE bulb" but infact its not a 70w equivalent, actualy you need to buy the next one up in order to gain the same levels of luminence.

just installed 3 Digiflux Dimmable 20W bulbs.
They work very well.
Very subdued and easy on the eye at minimum and bright enough to light up the whole living room for reading at max - though I would not say that it was "more bright than 100W standard bulb", but without measuring the lumens I'm only basing this on the fact that my retinas aren't burnt out when I look at these bulbs.
Strange warm up - there is no light at all for about a second, but when it does laggedly ping on the brightness is practically full.
Way too expensive, but a good solution for my lighting reuirements.

I've got one in my bedside light (60w equiv made by Philips I think) which is really good and I was very impressed. As Robert Dyas were doing BOGOF on them, I thought I'd buy a couple of 18 watt (equiv 100w apparently) for my room and lounge.

They are simply not as good and give off a particularly depressing light for the first 5 minutes while they warm up, even then the light simply isn't as good. I'm considering getting one of the 30 watt bulbs to see if they're any good, but at over £5 each, they aren't exactly cheap. I try to save as much energy as possible, but the technology needs to drastically improve this year for people to feel happy about the move. Saying that, I'm hoping these bulbs are just a stop gap until LEDs become useable considering the chemicals they put into manufacturing these things.

There is massive variation in the quality of fluorescents. Try the General Electric ones. Cheap and good.
