Take it easy on me, this is my first attempt and I know it's not perfect, but you stand in the snow in 15F weather and try it .
This is my Modamag Collossus with 8x Sony 18650 V cells, Osram 64642 150 watt bulb (rated at 5000 lumens at 24v) and AW 3 stage driver. The first comparison shot is a 5761 in a bored Surefire M4 with 2x Sony Vs - I lost the some text in the GIF conversion somehow - then the 64642 low, med, high.
