A series of bulb heads are attached to a power cord to provide overhead lighting for jobsites. The cord has a plug on one end and a female connector on the other end, so you can connect multiple strings to illuminate larger areas.

Style A lights are compatible with medium-base, screw-in CFL (compact fluorescent), incandescent, and LED bulbs (sold separately). They have a plastic-coated steel guard to protect the bulb.

Style B has built-in LEDs that last longer, are more efficient, and generate less heat than other light technologies. They produce a cool light appearance that highlights white/blue tones, which is good for inspecting. For use in wet environments, there is a seal between the lens and the housing to keep out dripping, splashing, and falling liquids.
