The lamp is held the promised 5000 lumens (how is that also go with two LEDs, the lamp without the heat death dies) just measured 2000 lumens from. In this mode, the lamp turns down only because of heat issues. In continuous operation at level 2 1200 lumens are possible, then the lamp is running but only 1.5 hours. The disc front was loose. Thus, the Ledsockel is not pressed against the housing. Causing overheating, and the tightness is also there, and I wonder how that is to be sealed: The water runs to the window and the silicone ring through. The command was also loose, in consequence of an overwound thread. The capacity of the battery information are also grossly wrong: instead of the promised 6400 mAh battery supplied the net 2200th
More than 1 Star can not be forgiven for so much "quality" and misstatements.
