Bayonet Base Light Bulbs

Single-Contact Base with Globe Bulb

Pins on the base lock these bulbs into sockets to withstand vibration. They're often used in machines and elevators. A bulb’s estimated yearly energy cost is based on 3 hours of usage per day at $0.11 per kWh.

Single contact bulbs cannot be sold to California, Vermont, Colorado, and Washington due to energy efficiency requirements.

Bayonet Base Floodlight Bulbs

Single Contact

Pins on the base lock these bulbs into sockets to withstand vibration. Often used in recessed can fixtures and track lighting, they produce a focused beam of light. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. The bulb with a warm light appearance has yellow tones. 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, withstand vibration, and are shatterproof.

Incandescent bulbs are traditional light bulbs.
