I've often thought Brinyte missed a trick by not producing an XM-L version of their D8.
Then I came across this XM-L modded D8. And it seems the D8 has a hefty solid brass pill. But it was the beamshots that got to me. The hotspot is so damn crisp. I've never seen an XM-L hotspot so clearly defined.
Then I found that UltraOK have the D8 at an almost reasonable price for such a solid host.
I have a 2-cell pre-production version of that light (sterile) that is my favorite XM-L thrower. It has kept my 'need' for a 7G5 or Catapult to a minimum.
When I finish my homemade thrower, I'll take some beamshots of it, this one, and a few popular ones for reference.
The most accurate and descriptive words I could use to describe this light are:
Maybe I'm missing something, but by the size of the door and distance in the pics you linked, I don't see any major difference from a stock C8 XM-L ...
This is not a "crispy" hotspot. It's just a crappy camera.
The reflector in this light is similiar to Tiablo A10 / Solarforce MPP-1 / Thrunite Catapult (in overall dimensions). It's OK, throws good, but nothing to drool at.
