Screw-In Base Light Bulbs
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).
Halogen bulbs are slightly more energy efficient than incandescent bulbs, but they generate more heat.
Bulbs that cannot be sold to the listed regions do not meet energy efficiency and/or mercury regulations.

Prefocus Base Light Bulbs
Small but powerful, these bulbs are commonly used in stage and security lighting. All have a neutral light appearance that is brighter than warm light. A bulb’s estimated yearly energy cost is based on 3 hours of usage per day at $0.11 per kWh. These halogen bulbs are slightly more energy efficient than incandescent bulbs, but they generate more heat.

Screw-In Base Floodlight Bulbs
Often used in recessed can fixtures and track lighting, these bulbs produce a focused beam of light. 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.
BR and R bulbs have wide beam angles that create broad beams of light. Their length makes them good for use in large can fixtures.
Incandescent bulbs are traditional light bulbs. Many have been phased out due to governmental energy requirements, but some are still available for special applications.
