Light bulbs have lit up quite a discussion over the past year as policymakers struggle to balance environmental needs with those of public safety. While incandescent bulbs are getting the off-switch because of their inefficient energy consumption, many have complained about the toxics and poor light quality produced by their fluorescent replacements. Now there’s a newcomer to the scene which promises to bring the best of both worlds. Called nanofiber bulbs, these new contraptions emit a warm, white light that is more agreeable to the human eye than fluorescents. But since they put out 55 lumens of light per watt, they are also five times more efficient than traditional incandescents. Sounds like a bright idea, any way you look at it!
