Bi-Pin 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. 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.

Bi-Pin Base Spotlight Bulbs
These bulbs produce a narrower, more concentrated beam of light than floodlight bulbs. Bulbs with a warm light appearance have yellow tones. Those with a neutral light appearance are commonly used in workspaces. A bulb’s estimated yearly energy cost is based on 3 hours of usage per day at $0.11 per kWh.
Halogen bulbs are slightly more energy efficient than incandescent bulbs, but they generate more heat. Those with a glass lens will contain glass shards if the bulb breaks.
Bulbs that cannot be sold to the regions listed are restricted by local energy efficiency requirements.
