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.

Two-Pin Wedge Base Plug-In Compact Light Bulbs
Often used in task lights, these bulbs are comparable to PL, Dulux, and Biax bulbs. 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.
CFL (compact fluorescent) bulbs are energy efficient, but take several seconds to reach full brightness. They cannot be sold to Canada because they do not meet local efficiency standards and exceed local regulatory limits on mercury (for disposal information, visit www.epa.gov/cfl).
