Sensor Switch The sensor will immediately turn on the light after motion is detected under continuous power supply, and turn off automatically after 5 mins if no motion is detected. The light bar will last as long as motion is detected. Its detect range of this light bar is max 26.25ft long with 120 degree sensing angle. In low light circumstance, your movement will trigger the sensor and turn the lights on automatically. Easy and Flexible Install This complete LED light kit adopts slim triangular shape, so it perfect for corner application and hiding behind doors or under counters. Each light bar has 3M tapes backing on both sides and 2 mounting ears to be fixed by screws. Every light bar comes with a female and a male connector on either end. So they can be easily connected together without trouble. We also included 3 extension wires in the kit for long distance application. For long distance application, you can also connect another kit together with the same power adaptor. Tips The extension cables are also sold separately. The sensor needs about 20s to power up each time only after the power is cut and restored. Connect up to 6 bars at a single run.
