Installation made there 15 days:
It was simple despite the instructions in English: No need to be polytechnicien to understand how ...;)!
The different elements seem of good quality despite the use of plastics for the solar sensor, the sensor sockets and fixtures.
Connection cable 5 meters between the spot and the solar collector: Very convenient to choose different locations and well exposed to both elements according to their individual characteristics.
Provide, in addition, a fastening system for the connecting cable: Adhesive, chutes, riders, etc ... Depending on the media so that it does not drape or drags miserably.
After a rainy day load 1/2 (South-West of France), the system works perfectly: The light is strong and even blinding if you look at the spot directly. Brightness is very white and "cold": This is the led!
You can adjust by successive pressures on two separate buttons under the sensor, the lighting time (30 seconds to 20 minutes) and the trigger sensitivity according to the ambient light (declining day black night).
The manufacturer indicates a burning time, fully loaded, of more than 3 hours ... I have not had the opportunity to test, especially since there is no charge indicator to know the status of the internal battery.
All in perfectly sealed air since from the installation I made (15 days), it rains without interruption while the elements are directly exposed to the weather and everything continues to work very well.
After several checks, with no evidence of moisture inside the spot, the solar sensor or movement detector.
I think the lighting area of approximately 5 meters wide and 11 meters long.
Very satisfied with the result, despite the very white color of this type of lighting.
