  • Patent number: 11162668
    Abstract: A portable lighting device includes a body having an interior cavity, a lighting unit supported by the body including a light emitting diode, and a terminal block supported within the interior cavity of the body. The terminal block configured to connect to a power source and provide electrical energy to the lighting unit to illuminate the light emitting diode. The portable lighting device also includes a port formed in the body in communication with the interior cavity. The port configured to allow an electrical wire to pass into the interior cavity to couple the electrical wire to the terminal block. The portable lighting unit further includes a wire clamp supported by the body at the port. The wire clamp includes a single actuator and a clamp. The single actuator is selectively movable relative to the body to move the clamp into engagement with the electrical wire passing through the port.
