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.

BR and R bulbs have wide beam angles that create broad beams of light. Their length makes them good for use in large can fixtures.

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.

CFL (compact fluorescent) bulbs are more energy efficient and last longer than halogen bulbs. It takes several seconds for them to reach full brightness. They contain small amounts of mercury (for disposal information, visit www.epa.gov/cfl).

Halogen bulbs are energy efficient.

Bulbs that cannot be sold to the listed regions do not meet mercury and/or energy efficiency regulations.

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.

Lock these bulbs into GU10 sockets with a twist. Often used in recessed can fixtures and track lighting, they provide a focused beam of light.

Bulbs with a selectable light appearance have a switch on the top, so you can match other lights in your room.

Get the most light out of a single socket. With multiple LED panels, these bulbs are as bright as light fixtures but don’t require wiring. Just screw them into an existing socket. Each panel tilts up or down, so you can aim light where you need it.

A built-in sensor turns these bulbs on when it gets dark, then off when it’s light out. Change the light appearance with a switch on the side.

PAR38 bulbs have a narrow beam angle that provides a focused beam of light. They’re a good choice for outdoor security lighting.

Convert any standard socket into a security light. These bulbs have a built-in sensor that turns them on when it detects movement in the dark. They shut off five minutes after motion stops. You can change the light appearance with a switch on the side.

PAR38 bulbs have a narrow beam angle that provides a focused beam of light.

Lock these bulbs into GU24 sockets with a twist.

Bulbs with a selectable light appearance have a switch on the side, so you can match other lights in your room.
