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.

Create a focused beam in displays. These bulbs are LED replacements for halogen bulbs, so they use a fraction of the energy and generate less heat. They also have museum-quality color accuracy, so colors appear as accurate and vibrant as they would in natural sunlight. The narrower the beam, the more concentrated the light. To install them, press the lugs into your socket or use the screw terminals at the base for hardwiring.

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.

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.

Brightness is measured in lumens; the higher the lumens, the brighter the bulb. Color rendering index (CRI) is a measurement on a scale of 0-100 of how accurately the light from a bulb represents an object's true colors; the higher the number, the more natural the colors appear. Any CRI value over 80 will show colors true to life. Bulbs with a warm light appearance have yellow tones. Bulbs with a neutral light appearance are often used in workspaces. Bulbs with a cool or daylight appearance have white/blue tones and are good for inspecting. A bulb’s estimated yearly cost is based on 3 hours of usage per day at $0.11 per kWh.

Fluorescent bulbs are energy efficient, but they contain small amounts of mercury (for disposal information, visit www.epa.gov/cfl). Plastic-coated glass bulbs are shatter resistant; the coating retains glass shards if they break.

Bulbs that cannot be sold to the areas listed exceed local regulatory limits on mercury and/or do not meet local efficiency standards.
