Product Features:                                                                     

1.Operating voltage: AC 100V-240V,Average Load: Max.800W

2.Motion Sensor Light Switch: Automatically turns on the light when a moving human body (or heat source) enter into its detection area, and turning off after a delay time.It can identify day and night automatically.

3.TIME DELAY: 8sec-7min adjustable,Environmental Illumination: 3 ~ 5000LUX daylight adjustable

4.Combined intelligent control and energy saving, Help to save 20%~80% of your energy.

5.Waterproof IP44,can be used in corridor, toilets, stair hall, balcony, washroom, garage, etc.



1.When the light is bright enough, it will not turns on, it is energy saving.If you need it to induce in daylight, you need to adjust it to daylight induction mode.
2.Install following the wiring diagram, after the careful check, connect the power supply.40 ~80seconds is needed for preheat.
3.Detecting will be affected by the environment and other factors , such as, temperature , walking speed, cloth,glass etc.
4.in order to keep the high sensitivity, please do not install the product in strong light environment and where there is strong cold or heat airflow.
5.This device have the function of repeat triggering, when people in the detecting area, triggering the switch, the device will restart the delay time,
so the delay time should be calculated on the last triggering.

Q: How do you attached or connect this to an existing light fixture?

A: just make the lamps and lanterns power input by the controller


Q: Can this be used with an existing patio light set with two 60 watt LED bulbs installed?

A: I have a slightly different-looking one but, yes, it can be used with any existing light as long as you can access its wires.


Q: How do you wire this in US? Black, white, green (ground)....wires

A: The red line connected to US standard electric black(The Hot),Black line connected to US standard white line(The Neutral).Please refer to the last image (Wiring Diagram) on the website


Q: what color is this sensor please?

A: The sensor is a true white color and black color.


Q: Would this work in combination with a 3-way wall switch to control a hallway light?

A: Yes it would. You wire it inline at the lighting fixture and then if the 3-way switches are supplying power, then it will be on and control the light.


Q: can it be connected to a dimmer switch that powers outside lamps?

A: Yes, it can. As long as your light bulbs outside are dimmable. Once you set the summer switch to your perfered brightness, the lights will come on at that brightness automatically.


Q: which wires connect to the electrical wires. The unit has black, yellow and red. No wiring diagram came with the unit. Thanks.

A: Scroll to the last picture on the item page. It has a diagram there.


Q: Does this trigger if you drive a car into its field of detection? I want to use this infront of my garage to trigger my lights when i drive in/out.

A: yes, it works, the maximum of the sensing area is 12meters.


Q: can I mount this directly on wall, or do I need an electrical box in which to make connections?

A: There is a box on the unit which allows for connections and you could mount to wall as well


Q: If the power goes off for 1 sec will the light stay on all night?

A: No, this doesn't have that function. It is motion sense and time delay only, no constant on mode. Max time is around 10 minutes if I recall the instructions correctly.


Q: Does this also include a dusk to dawn sensor? I'd want it to turn lights on only at night.

A: Yes...The lights will only turn on at dusk AND when the sensor picks up motion. The photocell is adjustable as to how dark it has to be for the lights to turn on. Also the length of time that the lights stay on after being activated can be adjusted.
