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.

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


LED (Horizontal, Base Up, and Base Down Operating Position)	CFL (Horizontal, Base Up, and Base Down Operating Position)

Change out the four-pin wedge base CFL bulbs in your fixture, or upgrade to LED. Often used in can lights, these bulbs are comparable to PL, Dulux, and Biax bulbs. 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 electronic ballasts. Check if your ballast is compatible by selecting a part number and clicking product detail.

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

Single-Pin-Base Tubular Light Bulbs

Swap new fluorescent light bulbs into your single-pin base fixture, or upgrade them to LED. Select a light appearance to match your existing lighting. Bulbs with more than one light appearance have a switch, which allows you to match other lights in the room.

T8 Bulb Shape—T8 bulbs can be used in T12 sockets that are wired directly to a power source.

LED—LED bulbs last longer and are more efficient than fluorescent bulbs. They work with sockets that are wired directly to the power source.

Ballast Compatible LED—Ballast compatible bulbs also work with most instant-start electronic ballasts. Check if your ballast is compatible by selecting a part number and clicking product detail.

Plastic-Coated Glass Bulb—Plastic-coated glass bulbs are shatter resistant. If the glass breaks, the coating keeps shards from falling.
