This lamp is perfect for illuminating a non-lit terrace in the evening and night. The power LEDs illuminate my terrace for some distance (between 5 and 10 meters). Despite a manual in English which is unfortunate, understanding of its operation is intuitive and posed no insurmountable problem. For the first operation, I had to wait a few hours of exposure to the solar light housing. Only regret was missing in the box, the 2 screws used to fix the solar station. I am thrilled with this purchase and recommend it to anyone who does not have access to an outdoor electrical outlet. I put 4 stars for the operating instructions in English and the two missing screws, for the operation of the lamp and the expected result, I would put 5 stars.
