I hate to start up another bulb bashing session, but this is of interest.


Folded functions?

I'm with you on the cfl's but what do you guys think about LEDs? We've got a residential school off-grid, so we always want new ways to improve our power efficiency.

(BTW, one way we improve our lighting efficiency is a school-only daylight-saving zone, as India doesn't have daylight savings time)

Looks sweet, but you have to remove heat.

It really raises cost on the LED bulbs. They don't have a good life expectancy now, but there is a well warrantied one at HD and Lowes now.

Last year we bought some LEDs for Rs 175 ($3.50) but they dimmed down to useless blue glows within days or weeks. This year we found a philips LED that we first got several months ago and they're all good so far, still white and bright, so now we've installed dozens more. They claim to be 2 W, and to my old incandescent sensibility I'd say they're similar to 40 or 60 W incandenscent, ie bright enough to get around the room or to read right under them, but not bright enough to read elsewhere in the room.

What do the bulb critics say?

LED's are fantastic. It's our grid that doesn't work very well with them and the band-aid is the problem. They like low voltage DC .... solar anyone? A few wired in series will be perfect for 12v.
 
I'm not dead! I feel happy! I'd like to go for a walk! I'll even read a tiny ad:
