Pins on the base lock these bulbs into sockets to withstand vibration. They're often used in machines and elevators.

Pins on either side of the base lock these bulbs into sockets.

Bulbs have two filaments, which operate at different brightness levels.

These bulbs are small, but very bright, so they're often used in flashlights and optical instruments such as projectors and microscopes.

Wire terminals allow you to connect these bulbs to a power source through a panel.

Fit these bulbs in tight spaces such as signs, control panels, indicators, and flashlights.

Often used as status indicators, in displays, or to check circuit function in prototyping and testing, these bulbs have wire terminals to directly install onto circuit boards.

Replace metal halide, high-pressure sodium, and mercury vapor light bulbs with longer-lasting, energy-efficient LEDs.

Often used in task lights, these two-pin wedge base bulbs are comparable to PL, Dulux, and Biax bulbs.

Replace bayonet base incandescent bulbs in exit signs with longer-lasting, energy-efficient LEDs.

Disinfect and sterilize air, water, and surfaces with shortwave ultraviolet radiation.

Stop vibration from shaking tubular fluorescent and LED bulbs loose.
