Did you get any definite info on the head diameter?
I just requested custom sizes of a few UCLp lenses from Chris at flashlightlens.com, including for the new Convoy L2 and UranusFire 818, so they are shipped and on the way. If this is plain glass, thinking it is, then a UCLp would be an awesome upgrade. He's got sizes in 73, 76, 88, and 93 now, but sounds like he can turn over a custom size in plastic (UCLp) quick. Glass is a whole # story - needs mins and time. The big UCLp's get a bit pricey, and still have to see if the 2.25 mm thickness will work out ok.
This light looks like it's made for the EFEST 4200 26650 cell - best cell on the planet right now, least I know of... I got a few more on order, planning on running 4 of them in this. Really for max throw, it comes down to the quality/design of the reflector. Some designs can kill throw, and can't be tuned, but there are also serious variations from piece to piece in reflectors, so never can tell. A UCLp should give a nice boost on throw - they always do.
Wish I could read Chinese - wonder what the X960 means, was hoping it's 96 mm head or reflector . 960 doesn't seem to match up to anything else, unless it's just a sort of model #.
Just fyi, it's SRK soup can style, super sized, 4 cells in parallel, but still, should be awesome runtime and maxing out the 4v capability of the emitter.
The handle is budget all the way - that slip over rubber sleeve, little weird, and the tail switch is kinda strange as well for alight like this, but who cares really - this light has just one purpose - max, and I'm thinking max throw.
Still, I'd probably drop in a Tiny25 with Bistro firmware - just because I can, and it's easy. Doing a Convoy L2 now, same way basically. Thinking of a de-domed XP-L V6 1D - got a couple in from IOS, but he's sold out of the LED's. Might have to get a couple XP-L V6 1A's from Richard. Could also go with a de-domed U4. I just have no luck with XP-G2's...
I'll try. Hoping to max it out for throw. Once I get it and measure the lens, I'll probably order a custom UCLp. Thinking of a de-domed XP-L, but I'm working on de-domed XP-G2's. Unfortunately, I don't have the capability to do much in a custom heat sink, but we'll see. I'd rather keep the cells 4P - easier to works thing out with a stock driver. I'm thinking this is between a COURUI D01 and TK61 in reflector diameter. Of course a lot depends on the quality/shape of the reflector to get top #'s.
Great for something this big at a decent price though.
