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.

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.

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.

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.
