If you are looking for motion detection right to your home or workplace, the 240 Degree Motion Detector Security Light with Dusk to Dawn Setting is a great solution. It features sensor technology that detects motion directly under the sensor and against the building and up to a 100ft outwards. Its DualBrite® technology provides low-level, accent lighting until motion is detected. When motion is detected, the light illuminates to full brightness until the ON-TIME setting expires. If you prefer, you can switch to 'dusk to dawn' coverage to ensure constant light throughout the night. Light is provided through 2 - 150 W max PAR38 Halogen Flood Bulbs (Not Included).
