I particularly appreciated the ease of setting up, packing the fate of just one and one has to activate with the key provided to reach the switch. Then the sun does the rest, it charges the battery and lamp diffuse light upon detection of any passage in the cell radius.
The lamp is waterproof so it is easy to find a location outside the light scattered by the LED lights correctly My car park has about 5M at night.
The small size and light weight of the lamp make it an asset discreet and easy to install.
