Bayonet Base Miniature Light Bulbs
Pins on either side of the base lock these bulbs into sockets. These bulbs are sized to fit tight spaces such as indicators and vehicle lights. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.
Incandescent bulbs are traditional light bulbs.
Wedge Base Miniature Light Bulbs
These bulbs are sized to fit tight spaces such as indicators and vehicle lights. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.
Krypton bulbs are known for generating a bright light, such as a flash in a camera. They last longer than incandescent bulbs.
Incandescent bulbs are traditional light bulbs.

Dual-Filament Wedge Base Miniature Light Bulbs
These bulbs are sized to fit tight spaces such as indicators and vehicle lights. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.
Bulbs have two filaments, which operate at two brightness levels. The first filament illuminates a light and the second emits a brighter light when activated similar to a tail light and brake light.

Bi-Pin Base Tubular Light Bulbs
Brightness is measured in lumens; the higher the lumens, the brighter the bulb. Color rendering index (CRI) is a measurement on a scale of 0-100 of how accurately the light from a bulb represents an object's true colors; the higher the number, the more natural the colors appear. Any CRI value over 80 will show colors true to life. Bulbs with a warm light appearance have yellow tones. Bulbs with a neutral light appearance are often used in workspaces. Bulbs with a cool or daylight appearance have white/blue tones and are good for inspecting. A bulb’s estimated yearly cost is based on 3 hours of usage per day at $0.11 per kWh.
Fluorescent bulbs are energy efficient, but they contain small amounts of mercury (for disposal information, visit www.epa.gov/cfl).
Bulbs that cannot be sold to the regions listed exceed local regulatory limits on mercury and/or do not meet local efficiency standards.
