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.

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.

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.

Turn standard light bulb sockets into standalone floodlight fixtures using these bulbs, which have an aluminum reflector to focus light downward and add a finished look. Rated for use in damp locations, they withstand humidity and moisture. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. These bulbs have a cool light appearance, which is good for inspecting because it highlights white and blue tones. A bulb’s estimated yearly energy cost is based on 3 hours of usage per day at $0.11 per kWh.
