While LED tri proof light could save 30%-50% electricity than ordinary fluorecent tube triproof fixture , motion sensor LED tr proof light , also we call it microwave sensor LED tri proof light can save another 50%-80% electricity , especially for the house , under ground parking , corridor , stairs...
Motion sensor is also called movement sensor , if nothing moves , the led three proof fixture won't produce light , or keep very low level light , and objects moves , the LED tri-proof light will turn to 100% brightness .
The triproof light with motion sensor have 2 different type:
1. On/Off sensor
This type motion sensor led tri proof light cound only be on and off , the sensor works as a switch to detect movement .
2. 3 step dimming sensor
This type microwave sensor led tri proof light should have 1-10V dimmable driver , and sensor is also more complicated than the on/off sensor , it have 3 steps :
off - N% brightness - full brightness
The parameters of the 3 step dimming sensor LED tri proof light could be set by the remote controller , such the detection area , the detection distance , the standby dimming level , the lighting time after movement detected ...
