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.
Incandescent bulbs are traditional light bulbs.

Index Base Miniature Light Bulbs
Offset pins on 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.
Bulbs have two filaments, which operate at two brightness levels. The first filament illuminates a light and the second emits a brighter light similar to a tail light and brake light.

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.
LED bulbs last longer and are more efficient than other technologies. They generate little heat and withstand vibration. Plastic LED bulbs are shatterproof.

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.
PAR bulbs have narrow beam angles that provide more focused beams of light than other floodlights. A short length allows them to fit in small can fixtures without protruding.
LED bulbs last longer and are more efficient than other technologies. They generate little heat and withstand vibration. Plastic LED bulbs are shatterproof.
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 energy efficient.
