I recently bought some LED light bulbs, made by Lights Of America, at our local Ace hardware store. Lights of America part number is 2026LED-30k and 2026LED-65k. So here are some of the claims written on the packaging: Uses 1.5W Replaces 40W bulb 90% more efficient than incandescent and halogen bulbs NOT on the package: Lumens rating Also missing: any mention of this product at their website. Okay, for starters, when I got home and tried them out, they definitely do NOT look as bright as a 40W incandescent bulb. Secondly, they're efficiency and power claims on the package are inconsistent with one another. 1.5W vs. 40W would mean 25 to 30 times more efficient, not 90% more. Finally, similar bulbs by Philips indicate these 1.5W bulbs are closer to the light output of a 10W incandescent. (Philips has 1W LED = 7W incandescent, and 3W LED = 20W incandescent) That's still an impressive 6 to 7 times the efficiency. I imagine they thought people would be put off by a 10W equivalence claim, since that is not a commonly used wattage. And to make a truly 40W equivalence would require 4 times the number of LED's. They are already charging $9 or $10, so perhaps they don't think they would sell if they had to charge more.
