Use these bulbs in standard sockets, panels, and appliances. 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 commonly used in workspaces. Bulbs with a cool light appearance have white/blue tones and are good for inspecting. A bulb’s estimated yearly energy cost is based on 3 hours of usage per day at $0.11 per kWh.

CFL (compact fluorescent) bulbs are more energy efficient and last longer than halogen bulbs. It takes several seconds for them to reach full brightness. They contain small amounts of mercury (for disposal information, visit www.epa.gov/cfl).

Bulbs with a reinforced filament resist burning out from vibration. They're also known as rough service.

These bulbs lock into GU24 light sockets with a twist. 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 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.

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 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 fluorescent bulbs. They generate little heat and withstand vibration. Plastic bulbs are shatterproof. Socket-ready bulbs work with most instant-start electronic ballasts, but not all. For a full list of compatible ballasts select a part number and view product detail. Ballast bypass bulbs eliminate the need for a ballast so the socket must be wired directly to the power source.

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.

Recessed Double-Contact Base Tubular Light Bulbs

T8 and T8/HO

LED bulbs last longer and are more efficient than fluorescent bulbs. They generate little heat and withstand vibration. To install, bypass the ballast by wiring the socket directly to the power source. Plastic-coated glass bulbs are shatter resistant; the coating retains glass shards if they break.

Four-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. LED bulbs are socket ready. They plug directly into a fixture and work with most electronic ballasts, but not all. Their bases are designed to fit multiple sockets.

CFL (compact fluorescent) bulbs are energy efficient, but take several seconds to reach full brightness. They contain small amounts of mercury (for disposal information, visit www.epa.gov/cfl).
