Miniature Candelabra

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.

Halogen bulbs are slightly more energy efficient than incandescent bulbs, but they generate more heat.

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.
