Greenstrides - a great place to get info on green products & practices written by a sustainable designer and member of the US Green Building Council - has a recent article on the latest in LED lighting. The 3 basic types of lights are your normal (1) incandescent light bulbs which last about 1000 hours; (2) CFLS - compact florescent lights which last an average of 10,000 hours; (3) and LEDs – light emitting diodes – which will last for 30,000 to 50,000 hours and they don’t have the little bit of toxic mercury the CFLs contain. And though they cost more, they last longer putting out less heat and using much less electricity. They are easier to find and use these days for interior or exterior lighting. Check out this greenstrides article for more information.
