Bi-Pin Base Miniature Light Bulbs

These bulbs are small, but very bright, so they're often used in flashlights and optical instruments such as projectors and microscopes. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.
Halogen bulbs are slightly more energy efficient than incandescent bulbs, but they generate more heat.

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). Plastic-coated glass bulbs are shatter resistant; the coating retains glass shards if they break.
Bulbs that cannot be sold to the regions listed exceed local regulatory limits on mercury and/or do not meet local efficiency standards.

Four-Pin Base Plug-In Compact Light Bulbs

Energy efficient and long lasting, these bulbs are often used in task lights. They’re comparable to PL, Dulux, and Biax bulbs. It takes these bulbs several seconds to reach full brightness. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. Bulbs with a warm light appearance have yellow tones. Bulbs with a neutral light appearance are often used in workspaces. Bulbs with a cool light 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. These bulbs cannot be sold to the listed areas because they do not meet local efficiency standards and exceed local regulatory limits on mercury (for disposal information, visit www.epa.gov/cfl).
