Heath Zenith SL-5525-WH 250-Watt Quartz Motion-Sensing Light, White. Heath Zenith's HZ-5525 bundles a motion sensor and a single halogen light in one package. The unit includes a selectable timer that lets you set the amount of time the lights stay on after motion stops (an automatic photocell deactivates the lamp in daylight). Alternatively, a manual override enables you to turn the light on and off at will via an existing indoor switch. The sensor has a range of up to 70 feet and detects motion in a 180-degree range with a maximum 3,400-square-foot detection zone. This model accepts halogen bulbs of up to 250 watts (included), but is Energy-Star compliant when used with 120-watt bulbs.
