A typical incandescent lamp (traditional light bulb) consumes 60 watts of power. How much do each of a compact fluorescent and LED lamp consume, in watts, to produce the same amount of light?
-
Sorry, that’s incorrect.
A typical incandescent lamp (traditional light bulb) that consumes 60 watts of power produces around 800 lumens. A compact fluorescent lamp emits the same amount of light while using only 13 watts. And an LED lamp consumes only 10 watts to give off the same 800 lumens.
