Types of Light Bulbs

LED and CFL Bulbs

This chart compares types of light bulbs.

CFL and LED light bulbs are energy-efficient alternatives to traditional incandescent light bulbs.

CFL bulbs are actually compact fluorescent bulbs that use 90 percent less energy than incandescent bulbs. But because light is produced by heat, they are hot to the touch.

LED lights are 75 percent more efficient than CFL bulbs. LED light is created by light-emitting diodes, or electrical conductors, so they stay cool to the touch.

Different types of light bulbs meet different needs. For the best light possible for a specific area, check the requirements for the lamp or socket where you'll use the light bulb before installing the bulb.
