The FBA and the "best price" were as always exemplary. Flawless, high-quality finish, robust new product! How to exchange the various lenses exactly not find in the manual, but on youtube. Who exchanges wrong loses the sharpness! Tip: Do something silicone oil on the lens thread, it went without just stiff you. The brightness is good in a darkened room, ("creak") noise can hardly be heard after the running-time (distance unit head incidentally, only about 1.00 m). I shine from the ceiling and walls and come as a deviant deep relaxation, absolutely good looks and great room atmosphere. If I were to use the part in celebrations, it would be an eye-catcher - really cool look. As long as the LED keeps and whether it is exchanged I do not know -> update follows then. For me full satisfaction. Honest buy recommendation.
