What's the difference between lumens and watts?

A lumen is a measure of light brightness while the watt is a measure of energy used.

A standard 60-watt incandescent bulb, for example, produces about 800 lumens of light. By comparison, a CFL bulb produces that same 800 lumens using less than 15 watts.

So with newer light bulbs designed to use less energy, wattage is no longer a reliable way to gauge a light bulb's brightness. That takes lumens.
