Twin heads on this flood light provide a crisp, clear, wide arc of light to secure a residential or commercial driveway, entryway or facade. The fixture uses 2 outdoor-rated 150-Watt incandescent or halogen PAR38 bulbs (sold separately). Hands-free installation is simple using the integral hooking wire. Mount the light on a wall or eave using the detachable mounting plate. Then, let the dusk to dawn photocell sensors automatically turn the light on at nightfall and off at first light. The impact- and weather-resistant ABS thermal polymer housing easily stands up to 50,000 hours of maintenance-free use, well beyond Commercial Electric 5-year warranty.
