What you get with this product
- Real savings on your bill – light turns on only when it detects sound and darkness, it doesn't stay on unnecessarily
- Simple installation in an existing junction box – connects directly between the 220V source and the LED bulb, no electrician needed
- Intelligent dual control – the photocell blocks activation during the day, the sound sensor responds instantly to voices or noise
- Compatible with light fixtures up to 40W – works with standard LED bulbs, wall lights, or ceiling lights
- Compact dimensions 33x16x21mm – integrates discreetly into any standard mounting box
- Adjustable thresholds – adjust sound sensitivity and the ambient light limit below which it activates
How it works and how to install it
The sensor combines sound detection with a photosensitive cell: during the day it remains inactive, and in the dark it reacts to sounds of 50-70 dB (voices, footsteps, claps). It is installed in series with the bulb, connecting the phase and neutral wires according to the included diagram. It does not require programming or complex settings – it works automatically after connection. The light threshold and sound sensitivity can be finely adjusted by rotating the integrated controllers.
Frequently asked questions
Can it be used outdoors, on the terrace or in the yard?
It is not recommended – the IP22 protection class is designed for dry indoor spaces. For outdoor use, you need at least IP65.
How long does the light stay on after detecting sound?
The lighting duration is fixed, approximately 30-60 seconds, sufficient for passing through the illuminated area. It does not have adjustable timing.
Does it work with old LED bulbs or only with new LEDs?
Compatible with any LED bulb up to 40W, regardless of model or age. It does not work optimally with incandescent or halogen bulbs due to higher power consumption.
