That’s not true. This one mentioned in the article uses 10.8 watts and only puts off 400 lumens. A standard 40 watt incandescent will put off about 460 lumens. The LED is getting about 37 lumens per watt compared to about 11.5 lumens per watt for the incandescent. That’s only about 3 times as efficient. A 25 watt compact fluorescent will put out closer to 60 lumens per watt, compared to the 37 lumens per watt this LED bulb gets.
LED technology is promising, and there probably will be general home lighting LED products on the market someday that really are super efficient, but for now compact fluorescent technology leaves LED technology in the dust when it comes to energy efficient home lighting products actually available to consumers. Don’t believe all the LED hype. These guys engage in some really misleading marketing practices.
