All that is written in a review of these lamps-all the way. Nothing to add. Quality content. Delivery fast. Works fine. The Rest Of the review
Full disclosure. Rack hlyupenkie, but if no wind or without a strong, it will come. Photo of panel look more, actually quite small, but light as big, good bar. Silver side of the aluminum, that good-will dissipate heat. The power supply when connected to the green light, cords of the power supply is very long, that much. THE bags have 2 Department. Convenient to put in one panel, in another-BPS (as arrived). Drive fast, there were problems with courier (MY fault). The Seller is extremely friendly, that very much.
