About Brightness and Light Appearance

Find the right lumen level to brighten your space. Then, compare the way warm, neutral, and cool lighting affect the appearance of everyday objects.

Two-Pin Wedge-Base Plug-In Compact Light Bulbs

Often used in can lights, these bulbs are comparable to PL, Dulux, and Biax bulbs. Change out your CFL bulbs or upgrade to LED. Select a light appearance to match your existing lighting. If you’re not sure what temperature you need, choose a bulb with more than one light appearance. You can adjust the temperature with a switch.

LED—LED bulbs last longer and are more efficient than CFL bulbs. You can choose bulbs that work with or without a ballast—some bulbs can do both.

CFL—CFL bulbs contain small amounts of mercury. For disposal information, visit www.epa.gov/cfl.

Ballast-Bypass LED—Ballast-bypass bulbs work with sockets that are wired directly to the power source, which cuts down on maintenance. If your fixture has a ballast, you’ll need to remove it.

Ballast Compatible LED—Ballast-compatible bulbs are a quick replacement for CFL bulbs, since they work with most magnetic ballasts. Check if your ballast is compatible by selecting a part number and clicking product detail.

Cannot Be Sold To—Bulbs that cannot be sold to the listed areas do not meet local regulations for mercury content or energy efficiency.
