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.

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.

Fluorescent bulbs are energy efficient, but they contain small amounts of mercury (for disposal information, visit www.epa.gov/cfl).

LED bulbs last longer and are more efficient than fluorescent 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 instant-start electronic ballasts, but not all. For a full list of compatible ballasts select a part number and view product detail.

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. Ballast bypass bulbs eliminate the need for a ballast so the socket must be wired directly to the power source.

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). Plastic-coated glass bulbs are shatter resistant; the coating retains glass shards if they break.
