Tata Power EZ HOME T5 LED Tubelight has an inbuilt microwave motion sensor, which is used to dim the T5 LED Tube in case there is no movement in the detection area. If the motion is detected, the T5 LED tube glows at full brightness and dims off in case of no movement. It detects any moving object that is cutting through the microwave signal emitted by the microwave sensor, and it immediately makes the light glow with full brightness.
