LED DIY flashlight at 100,000 lumens with water cooling

YouTube user Samm Sheperd recently videotaped a demonstration of his homemade flashlight at 100,000 lumens. System power - 800 watts. He made it himself, adding a self-made cooling system from a water bottle, a water pump, PVC pipes and a radiator with a cooler.

The lamp uses LEDs of 100 W each, plus lenses (the author glued them with epoxy and then removed the protruding parts). The LEDs are connected in parallel, each equipped with a 1 Ohm ceramic resistor. The body is made of aluminum slats and a wooden platform. The assembly process used a large amount of superglue and epoxy.

The title of the video tells us that the flashlight generates a beam of 100,000 lumens. This is true, despite the fact that the video immediately shows only 8 LEDs with a brightness of 9000 lumens each. The fact is that after assembling the device, the author added three more LEDs, bringing its total brightness to 100,000 lumens (thanks to the author of the comment ). At the same time, the beam is quite wide, in contrast to the narrow-focus powerful lamps with which this home-made is compared.

As for batteries, their capacity is not specified, but in the comments the author says that the total battery life of the lamp is about 6 minutes. The water in the system heats up to 82 degrees Celsius.

And here is a demonstration of this miracle of technology:
