Cordless tool lighting operates on brand-specific power tool batteries to illuminate remote jobsites, emergency scenes, and other locations with limited or no access to wired power. These lights are portable for carrying between locations. Their batteries can power other tools of the same brand to allow swapping batteries between tools. Flashlights provide a personal light source for on-the-go illumination to navigate dark or dimly lit areas and shine light into cabinets, control panels, machinery, and other spaces without direct light. Work lights and jobsite lights spread light over a wider area than flashlights and sit on or mount to a surface, keeping both hands free to work.
