Bi-Pin-Base Floodlight and Spotlight Bulbs

MR16 Bulb Shape

Often used in display and landscape lighting, these small bulbs produce a focused beam of light. Bulbs that are 50W or higher are often used in overhead projectors and microscopes. They’re brightest at the center of their beam angle; the edges of the beam are about half as bright. The narrower the beam, the more concentrated the light.

LED—LED bulbs last longer and are more efficient than halogen bulbs. They generate little heat and withstand vibration.

Plastic Bulb—Plastic LED bulbs are shatterproof.

Cannot Be Sold To—Bulbs that cannot be sold to the regions listed do not meet local energy efficiency requirements.

Festoon-Base Miniature Light Bulbs

Light up automotive interiors, license plates, and dome lamps. These bulbs have pointed metal end caps that snap into place within festoon sockets. To replace a festoon bulb without a trade number, match the overall length, base diameter, and voltage. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

Dual-Filament Wedge-Base Miniature Light Bulbs


Tubular	Wide Wedge Base

Often used in taillights and brake lights. These bulbs have two filaments that operate at different brightness levels, with the second filament shining brighter when activated. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

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

LED

CFL

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.
