E27 5W LED Infrared Motion Sensor Pir Warm White Light Bulb Lamp auto switch Stairs light


Specifications:

1.color: warm white
2. Input voltage: AC85-265V
3. The output power: 5 W
4. Light angle: 120 °
5. Material: Aluminum + PC
6. Lamp style: E27
7. Life :> 50,000 hours
8. CRI: 70-80
9. The luminous flux: 5W 450lm ± 10%
10. Detection range: 5-8m


Work principle:
Smart body sensor PIR bulb, when person gets in sense range, bulb will light up and auto light off after 1 minute when person leaves; also it will not light up in the day, only work in dark environment or at night


Trouble removal:

1. When install it, it will auto light up and off, occasionally it can auto light up, the reason may be there's animal moving or bulb turns to hot place, or install angle is not correct
2.If it auto light up every 8s and light off every 30s and it repeats that, now you should check whether there's person or animal moving around it, or can take the bulb to another room for checking.


Operation Tips:


1. Bulb can be installed near stair, better to let bulb head turn to exit/entrance

2.The bulb should be keep far away from heater, air condition, fridge, stove, such places which temperature is high and sensitive (over absolute zero degree object will probably make bulb light up)

3. Don't put any shield, furniture, or big object around the bulb

4. Don't turn it to the window for avoiding hot air /white light perturbance, and body motion to wrongly light up the bulb

5. Don't install bulb near gate or airway
