Effective and "plug and play" (no installation required).

Put in my garage, no more children who forget to turn off the light.
Detection angle 360 ​​°.
I also opted for this system to have light when I enter by an entry that has no switch.
The big advantage and there are no facilities to achieve.
I have 3 bulbs in the garage, I put 3 detectors.
Attention must I believe a minimum of Watts per bulb for this to work.
I think it's 20 or 30 W.
A sensor was faulty on delivery Pearl M.EN arena and returned another.
It's been more than 6 months that everything works perfectly.
Very pleased with this purchase, for less than 10 socket.
