This is the Elektro Lumens Kong-12-XML, designed and manufactured by Wayne Johnson.
Kong-12-XML has twelve Cree XML LEDs attached to a large aluminum heat sink, and mounted in the flashlight.
Kong-12-XML is powered from twelve 18650 Li-Ion batteries.
The batteries are arranged in three banks of four (series of four batteries). The 3 banks of four batteries power the twelve XML batteries, which are also wired in three banks of four.
The voltage is a nominal 16.8V, and I use a small amount of resistance to keep the power level at around 3A per bank, a total of 9 amps of power, or, around 151 watts of power.
Each LED is putting out around 1,000 lumens, for a total brightness on high power of around 12,000 lumens! For a brightness comparison, a European standard HID headlight is 2,200 lumens.
The beam is around 8 degrees, not a pencil beam but not a flood beam either, and there is a lot of side spill.
And here is a link to a YouTube Video describing this flashlight a bit.
