So I decided to set this lamp above my door so that it is waterproof and so adapted to our humid climates.
The installation was relatively simple (although I delegated to a handyman), I looked and it was fast. We must follow the manual and there will be no worries. The screw, ankle and a key to activate are in the box.
The lamp has enjoyed the sun on the end of the afternoon and well despite only 2-3 hours of sun, at night, we did a lot of testing and it shines well. Frankly, it's nice.
The lamp is designed so that the beam is directed downwardly. Now the garage door is illuminated and a large halo as before so that I can easily open with my keys (or when someone else comes out if we use that door), rummage through my bag to see if j 'have not forgotten something when I'm going. The lamp power was a pleasant surprise! I do not expect a reach of 4-5 meters. The lamp detects movement at that distance too. One enters the detection field and presto, the lamp turns on (or off) when you move away.
