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.

- Global Warming
A term used to describe the phenomenon of Earth’s rising average near-surface temperature. Although such fluctuations have occurred in the past due to natural causes, the term is most often used today to refer to current warming trends. Most scientists have concluded that this is very likely due to the observed increase in human-generated greenhouse gas concentrations in the atmosphere.
