Adjusting the duration time
The length of time that remains switched on after activation can be adjusted from (10±5) seconds to (4±1) minutes. Roatating the TIME knob anti-clockwise will reduce the duration time
Adjusting the LUX control level
The Lux control module has a built-in sensing device (photocell) that detects daylight and darkness. Rotating the LUX knob anti-clockwise is from light (sun) to dark (moon). The (sun) position denotes that the floodlights can work at day and night, and the (moon) position only works at night. You can set to operate the unit at the desired level by adjusting the LUX knob.
