The GE 100W Replacement LED uses just 16 watts, for a very impressive 100 lumens per watt. It costs less than $2 per year to use. The incandescents that came before it cost over $12 per year, assuming they last that long.
Compared with the Utilitech 100W Replacement LED (left), GE's omnidirectional bulb has a more even light distribution. Notice the lack of dim spots on the lamp shade, and the uptick in brightness below the bulb.
