Screw-In Base Miniature Light Bulbs


These bulbs are sized to fit tight spaces such as signs, control panels, indicators, and flashlights. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.
LED bulbs last longer and are more efficient than other technologies. They generate little heat and withstand vibration.

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 or daylight 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.
