Microwave sensor led tube special for parking lot, garage: you can dim the brightness and standby time by yourslef.
when car/people/any subject move, the tube will be 100% brightness; when no movement, the tube will be just 0/5%/10% brightness.
Working principle: Doppler radae sensor, much more sensitive and stable than PIR sensor led tube.
