Lately theres been alot of talk here about the compact florescent lightbulb. Nice bulbs, but if you dont like florscent light, theres not much you can do. Recently I saw what was billed as a full-spectrum lamp. The salesman couldn't help me at all, so why not ask the net. Are these any good? is it like sunlight?

Nor can you spell it. Regardless of whether or not Frank can spell it right, I agree that the light from compact fluorescents is miserable. My in-laws have installed them all over their house, and it drives me crazy to be there after dark. I'm fond of halogens. More light per watt, long life, nice spectrum. But they aren't cheap and they aren't as energy efficient as fluorescents. So I guess Frank was right. -- Jerry Callen jcallen@encore.com

The light they produce is approximately the same color as incandescents, a soft slightly yellow light. The bulbs are Philips SL*18, and I bought them at Pascal (generic houseware store) for $29.95. Phillips claims they last 1 to 8 years, depending on how long they are on each day. JD (jdwhite@alzabo.UUCP) "In an insane society, a sane man must appear insane" - Spock

Phillips claims they last 1 to 8 years, depending on I have a couple of these. Very pricey, but the light is of good quality, nice color, no flicker. Output in lumens is very close to a real 75 W bulb. (1100 vs 1190, <1190 if you have soft white or similar bulbs) Their rated life is about 12 times that of a regular bulb, which can be very attractive in fixtures that are difficult to change. Only drawback (aside from price and larger size => doesn't fit all fixtures)) is they can take a long time to warm up, especially in the winter. Full warmup can take maybe a minute if the temp is around 60. Anyway, much better than the Panasonics, which flicker when they come on and only give 720 lumens. The shape is more attractive than Lights of America, but LOA seems brighter and comes on instantly. LOA is the only CF I've seen that does come on instantly. If you are used to turning the lights on and off when you enter and leave a room, lights that are slow to turn on can be annoying. -- Intentions are often more important than capabilities.

Halogens are certainly better than regular incandescents and have no equal for a fine point source, but they're still not that efficient. My calculations show a 500 W Q-H at 21 lumens/watt compared to 16 lumens/watt for a 75 W I. However, a 150 W I gives 19 l/w and a 300 W I gives 21.2 l/w. I don't have any numbers for the lower power Q-H and would love to get some. -- Intentions are often more important than capabilities.
