+1 I personally tested a variety of AC-powered LED light bulbs. Not a single one survived more than eight months -- on clean San Francisco power. There's a reason that these are not for sale in average hardware stores -- they aren't ready for prime time. The LEDs don't seem to fail, but the circuitry around them certainly does. They all advertise 100,000 hour lifetimes, too :--( don't believe it. Most of the developing world uses linear fluorescent bulbs, which are more power-efficient than the vast majority of LEDs (and more efficient than compact fluorescents). I suggest a return to the main topic (laptops / education). John _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
