Screw-In Base Floodlight Bulbs
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. Bulbs with a cool light 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.
PAR bulbs have narrow beam angles that provide more focused beams of light than other floodlights. A short length allows them to fit in small can fixtures without protruding.
LED bulbs last longer and are more efficient than other technologies. They generate little heat and withstand vibration. Plastic LED bulbs are shatterproof.
Halogen bulbs are slightly more energy efficient than incandescent bulbs, but they generate more heat.

Screw-In Base Spotlight Bulbs
These bulbs produce a narrower, more concentrated beam of light than floodlight bulbs. 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 light 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.
PAR bulbs have narrow beam angles that provide more focused beams of light than other spotlights. A short length allows them to fit in small can fixtures without protruding.
Halogen bulbs are slightly more energy efficient than incandescent bulbs, but they generate more heat.
