The only way to know for sure would be to remove the lens from the lights and note the difference with and without.
An aspheric lens even if flood-zoomed out will still concentrate emitted lumens. Compared to a mule which is basically a wide open emitter.
The mule DIY builds I have used were basically maglites without the head/bezel, and the LED elevated “up” on a copper platform to dissipate the heat. So in essence the combined effect of “cutting back” the bezel and lifting the emitter. If you wanted to DIY one of the hosts you mentioned it might be easier to grind down the bezel than elevate the emitter.
The annoying thing about mule designs is they blind everyone within eye-shot, even at the lowest lumen settings. There’s simply no way to aim them away from peoples eyes who don’t want to be blinded. The simple reason being that they don’t have a beam pattern. As a result I have found them difficult to use as camping/backpacking lights. They are great for the operator, awful for anyone else. I was with a CPF’er who had a triple mule in a D mag host and when I looked at it it scorched my vision and I was left with residual visions of the laser scope from the Predator movies… annoying to say the least.
My guess would be these lights try to alleviate that condition to some degree, with a flood-focused convex lens. The old zebralight headlamps (~10 years ago) had a small convex lens optic… for this very reason.
