Choose the Correct Fit
Select 180-degree coverage for a directed work area or 360-degree coverage around the light. The metal hook supports secure overhead placement.
Use M18 battery power or AC power. ONE-KEY adds customizable settings, while the AC inlet and outlet support the manufacturer’s connection arrangement.
Installation & Care
Switch off and disconnect power before cleaning or hanging the light. Inspect the hook, lens, protected AC plugs and security cable.
Keep ports free of debris and do not treat IP54 as permission to submerge the light. Follow the manual’s loading limits when linking AC-powered lights.
