I got mine from the aliexpress link in the other thread from the Boruit store. I work in a filthy shop so hate to take in my more expensive lights.
I had a 5000k XM-l waiting for a host and I ordered one of the Convoy lenses, beam profile is beautiful. No hard lines of demarcation between spot and spill.
Often gets used for 8 hrs. UI works good for daylight use in a dark shop. There is light but never where I need it. One click turns it on in the middle output which might be blinding for nighttime use but fine at the shop. It just runs and runs at that level with a charged battery.
Internal battery charger stops short of 4.2V on mine, 4.1V or so. no biggie.
You can wallow out the inner edge of the bezel slightly with a Dremel sanding drum to accept the Convoy lens and there is a groove that the o-ring will fit into from the rear. The o-ring behind the lens seats fairly securely so it not only retains the optic but offers some protection from water or debris entering the light.

I think the point that Jason made about different manufacturers is something to consider when buying. If all of the comments made on both threads were about the Boruit model they may not apply to a knockoff. OTOH I don’t remember ANY branding on mine so probably hard to tell what you get!
