Screw-In Base Light Bulbs
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.

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.
Xenon bulbs are known for generating a bright light, such as a flash in a camera. They last longer than halogen and incandescent bulbs.
