I'd considered mentioning a bored Elzetta Bravo, but their prices stopped me. I'd completely forgot about the Bones and agree that it's worth considering. The AVS, and therefore Bones, has a very useful beam pattern that's similar to the M61HOT.
My Bravo with AVS, which is supposed to deliver the same performance as the Bones, delivered 1.05 lux at 100 yards when fed by two CR123s. It will deliver a bit under that when fed by an 18650.
Run time would only be about 30 minutes, but two 18350s increases the Bones' output to ~900 lumens. My AVS, when fed by two 17500s, delivered 1.97 lux at 100 yards. The downside to running dual Li-Ions in the Bones is that it doesn't have any low voltage protection. If the cells are not protected, then the light will completely drain them while output is still bright. I don't have any to confirm, but protected 18350s are likely too long to fit within the body.
At a distance of 12 feet from the wall, the M61HOT's innermost spill is roughly 6 feet in diameter. It has less defined boundaries between spot, inner spill, next outer spill, and outermost spill regions than the AVS head or Bones. At the same 12 foot distance, the AVS head's innermost spill is easily measured to also be 6 feet in diameter.
