Flashlight is based on a 8-LEDs Luminus SST-90 (2250 lumens), all the LEDs are glued with hot melt to a massive radiator. It is easy to calculate that the power of the flashlight with 8 LEDs SST-90 is 2250х8=18000 lumens! The power of the flashlight is based on 8 batteries 18650 and is 29.6 V.
The photo shows not only the design of the flashlight, but its power compared to street lamps and car headlights.
