New low cost LED Light Bulbs

Posted by easy eco blog, February 4th, 2009

LED Light bulbs are finally coming down in cost. They use 90% less power than incandescent bulbs, which is even LESS than compact fluorescent lightbulbs. (CFL) A 40 watt LED bulb uses only 1.5 watts versus about 8-10 watts for CFLs. Lights of America may be overstating the light output at 40 watts though. Westinghouse has their 3 watt LEDs rated for 7 to 20 watt.

They are rated for about 30,000 hours versus about 6,000-12,000 for CFLs. Westinghouse rates their at 50,000hrs. They contain no mercury so they can be disposed of normally, unlike CFLs.

Costco and a local Ace Hardware carry them for under $10. Prices should drop further and light output should rise as volumes increase.

Consider them for when you need new bulbs.
