Abstract

A work light for work or task areas which uses light-emitting diodes (LEDs) as the source of light. LED clusters are mounted on a circuit board which is located in a housing. The LED work lights may be powered by conventional 120 or 240-volt electrical outlets, a DC generator, a battery, a battery pack, or a car adapter.
