With it's ability to clamp to materials up to 6.35mm thick, including pipe and 2-by lumber, this light makes mounting a breeze. This clamp light produces up to 400 lumens of LED light output on flood mode to illuminate any space. It's unique head allows you to adjust from flood mode (400/200 lumens) to spot (200/100 lumens) mode with a simple pull of the head. Cycle through two brightness settings (high/low) in each mode to fully customize your illumination.
