Frequently Asked Questions

Q: Will this PIR motion sensor switch work with my existing LED bulbs?

A: Yes! This infrared sensor switch is compatible with most LED ceiling lamps, downlights, panel lights, energy-saving bulbs, and standard bulb lamps — as long as the total load is between 3W and 40W. It works on both 110V and 220V power supplies (AC 85–265V), making it versatile for homes in the US, Europe, and beyond.

Q: Can I install this motion sensor light switch outdoors?

A: This sensor is designed for both indoor and outdoor use in covered areas such as balconies, courtyards, and garages. It operates in temperatures from -20°C to +40°C. However, avoid direct exposure to rain or high moisture environments — do not install in open wet areas or bathrooms.

Q: How long does the light stay on after motion is detected?

A: The sensor has a built-in time delay of approximately 45 seconds. After movement stops being detected within the 4–6 metre sensing range, the light will automatically turn off after around 45 seconds — saving energy and requiring zero manual interaction.

Q: Does this sensor activate during the daytime?

A: No. The sensor includes a light-sensing feature that prevents it from activating in well-lit environments. It only triggers the light switch in low-light or dark conditions, so you won't waste electricity during daylight hours.
