The Dual Brite system causes the lumination to go into a low-light mode during the night, when no motion is detected. The light is still on, but at a lower level, conserving energy costs for you when no one is near the lumination. When motion is then detected, the light will fully illuminate, giving you the lighting you may need when you'll need it.
The sensor on these lights generally covers a full 180 degrees, with a range of 30 feet. This makes it ideal to pick up movement on both sides of the front door or front porch area, too as from the front.
Sensitivity on most of these lights is adjustable, and numerous of these lights also have a manual override feature, allowing you to use the light as a standard, non-motion-sensor, light. Outdoor Decorative Motion Lighting.
