Cordless tool work lights and jobsite lights spread light over a wider area than flashlights and operate in areas without wired power or nearby outlets for corded work lights. They eliminate the tripping hazard of a cord and run on brand-specific power tool batteries, which can power other tools of the same brand. Also known as task lights, these work lights, site lights, and tripod lights sit on or mount to a surface, keeping both hands free to work. They supplement natural light and general lighting for construction, assembly, maintenance, and other jobs that require additional illumination.
