These bulbs are sized to fit tight spaces such as signs, control panels, indicators, and flashlights. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

Incandescent bulbs are traditional light bulbs.

These bulbs are small, but very bright, so they're often used in flashlights and optical instruments such as projectors and microscopes. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

Halogen bulbs are slightly more energy efficient than incandescent bulbs, but they generate more heat.

These bulbs are sized to fit older telephone switchboards, signs, instruments, and indicators. 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.

Wire terminals allow you to connect these bulbs to a power source through a panel. These bulbs are sized to fit into tight spaces such as signs, instruments, indicators, and flashlights. 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. They require a resistor to limit current (not included).

Infrared LED bulbs are often used in night vision goggles, thermal imaging cameras, and TV remotes. Infrared bulbs produce light that is invisible to the human eye and emits more heat than incandescent light bulbs.

Ultraviolet LED bulbs are often used to sterilize surfaces, cure adhesives, and detect leaks. Ultraviolet light is invisible to the human eye.

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.

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. As LEDs, they last longer, are more efficient, and produce less heat than other types of bulbs. Vibration won’t cause these bulbs to malfunction. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. They require a resistor (sold separately) to limit current.

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.

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.

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.

Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

2-way bulbs operate at two brightness levels, as in high- and low-beam headlights.
