If you’re looking to buy a bulb that will give you the amount of light you used to get from a 60-watt bulb, for example, you’ll now look for 800 lumens. This graphic shows the number of lumens produced by common incandescent bulbs. Using lumens helps you compare apples to apples when you shop for light bulbs.

By comparison, an LED (light-emitting diode) bulb produces that same 800 lumens but uses only about 9 watts.

Today’s light bulbs are designed to use less energy.
