To begin with, and this is important, the manual is well done and French with explanatory diagrams and text. Consequently, I was able to install this particular spot without much difficulty over the housing opening (simplissime once overcame the difficulty of the security mechanism) for inserting the batteries. You fix wherever you want and then just do it to make a 180 ° rotation of the head of the spot to guide the light to your wish.
The lamp is designed as it is waterproof, meaning it will withstand the rain and that's a big plus for an outdoor lamp mainly in temperate regions. I put in my country house to illuminate the bottom of the garden which is not illuminated by my outdoor lamp. I positioned this spot near my tool shed (yes, I happen to go winter gold I was tired of always having a flashlight with me). And I can assure you that as soon as I enter the sensor field (in 6- 7 meters) spot lights and illuminates almost as full days (in the middle of spring, the insects start flying toward the spot ). This is the result of 300 lumens, I assure you, it's very powerful.
In any case, the motion sensor works well. It turns off after about 20 seconds if it detects no movement. when I came out of the fields. And of course, the spot does not work in daylight.
A remarkable result without electrical installation. The manufacturer promises a lifespan of 50 000 hours of LEDs, I want to believe.
Ultimately, a product well thought out, well designed, allowing you to have a powerful lighting in your garden, home or any other dark place without the need to mount an electrical installation.
