Light up large signs or outdoor areas without running wires underground. Aim their solar panels at the sun, and these floodlights will charge all day. They turn on automatically at dusk and off at dawn. The batteries are large enough to power them for at least two nights, so they’re reliable even in cloudy weather. These floodlights are rated IP65, which means they’re sealed to keep out dust, sprinklers, and rain.

Style B are designed to run at full brightness all night. If you only need them on at certain times, you can also download an app to control when they turn on or off. These floodlights have insulated lead-acid batteries that can charge in temperatures as low as -20° F. They have an integrated kickstand with pre-drilled holes that doubles as a mounting bracket. Use it to prop them up or to secure them in place. Mount the solar panel and batteries to a pole (not included) and connect them to the lights with the included cord.

Hang these lights in garages and covered walkways to create a safe, well-lit path. They’re also known as canopy lights. All are either UL or ETL Listed for use in wet locations. Select a light appearance to match your existing lighting. If you’re not sure what temperature you need, choose a light with a selectable light appearance. You can adjust the temperature with a switch.

Fasten these lights to a ceiling or to an outlet box.

Styles B and D illuminate both the ceiling and the ground, so your space feels brighter and larger. When replacing older fixtures, use a mounting plate (sold separately) to cover any hole larger than the dimensions of the new fixture.

Lights with a light sensor automatically turn on in low light conditions. When adding a motion sensor to a light that doesn’t already have one, you’ll also need a remote (sold separately). Use the remote to set the motion sensor’s reach and adjust how much darkness triggers the light sensor.

Lights rated IP65 are sealed to keep out dust and driving rain.

Often used in task lights, these bulbs are comparable to PL, Dulux, and Biax 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 often used in workspaces. Bulbs with a cool light 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.

CFL (compact fluorescent) bulbs are energy efficient, but take several seconds to reach full brightness. They cannot be sold to the listed areas because they do not meet local efficiency standards and exceed local regulatory limits on mercury (for disposal information, visit www.epa.gov/cfl).

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.

Halogen bulbs are slightly more energy efficient than incandescent bulbs, but they generate more heat.
