Steinel presents a perfected technology and upmarket design that provides outstanding value for money, it's tilting and swivel sensor lens permits exact adjustment of the detection zone to suit individual requirements. It has a simple adjustment of light 'ON' time threshold by control dial. This PIR sensor can be mounted on walls and ceilings.
I purchased a sensor for an existing porch light. I would recommend to anyone and was particularly pleased to find that it was not made in China I have installed it and it's great.
