I asked this

and someone suggested LED bulbs, which I’ve not seen before for domestic use – I’ve only seen compact flourescent (energy savers) and ordinary incandescent bulbs. Anyone used the LED ones? are they good?

a different type of light brighter close in but not for distance

I’ve heard of them, but I have not seen them in the stores yet. I recall a story earlier this year in which they predicted these LED bulbs would take over the market within two years.
What makes these so special, is that no one has ever produced a white LED before. Individual LEDs emit a single frequency (color) of light.
EDIT: I found a source. (Link Below) 60 Lumens seems to be about the limit for a direct replacement bulb. A GE 15 Watt Standard light bulb puts out 110 Lumens.
Let’s hope there big improvements in store.

I used 16 of them in a 6 by 2m bathroom.Had to change them ,they gave off about the same amount of light as a candle.

Yes I have 4 of them in my kitchen and although they are good for direct light, they will not light around the room. The flourescent bulbs are better but take some time to warm up.

They are the coming thing, as someone noted. But they are not really ready for prime time. Sorta like the long long time it took for Compact Flourescent Lightbulbs (CFLs) to finally be reasonable in price and finally small enough to fit most common fixtures. As someone noted, LEDs until recently were not available to produce white light, but that problem was recently solved. But it will still take a few years before a good white light will be available. Most LEDs you see, such as in flashlights, have the blueish light. Same with those annoying bright blue car lights you occasionally see. The beauty of LEDs is that they do not produce any heat, or an insignificant amount and use very little energy. CFLs are much more efficient than incandescents but still produce some heat and use more energy than the LEDS.
