Bayonet Base Miniature Light Bulbs
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.
LED bulbs last longer and are more efficient than other technologies. They generate little heat and withstand vibration.
Incandescent bulbs are traditional light bulbs.

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.
Incandescent bulbs are traditional light bulbs. Many have been phased out due to governmental energy requirements, but some are still available for special applications.
