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.
LED bulbs last longer and are more efficient than fluorescent bulbs. They generate little heat and withstand vibration. Ballast bypass bulbs eliminate the need for a ballast so the socket must be wired directly to the power source.
Plastic-coated glass bulbs are shatter resistant; the coating retains glass shards if they break.

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.
LED bulbs last longer and are more efficient than CFL bulbs. They generate little heat, withstand vibration, and are shatterproof. Plug socket-ready bulbs into an existing fixture with a compatible ballast.
