Made a D80V2-SBT-90.2 today.
I had a 5700K Luminus SBT-90.2 from Neal that I did an output test on and it needed a host. Of course a big head thrower is the obvious way to go but I have a FT03 with this same led coming in the mail (some day it arrives) so that is already taken care of. So I went with the best 18650 host on the market (thanks to TheOnlyDocc 
who worked together with LuckySun, Lexel and BLF to make this finetuned version), the Wildtrail D80-V2. DBCustom beat me putting this led in a small host (he used a X6), but I think it is more than worth the trouble.
The challenge was to fit the led in the reflector that was never made for this fat led, and get it focused. I hoped that when the reflector hole was reamed so that it fitted flush around the black frame on the led that holds the glass window, so sitting on the led base, that the focus was ok too. And luckily that was quite right. With that hole size a thin edge of the reflector base remained and that was all that was needed to make it work. I slightly sanded that edge and then put a layer of Kapton tape on the edge, and also a layer of Kapton tape around the black frame on the led. This was needed because there are a couple of conducting dots in the corners on the led.
After this, this mod only needed two spring bypasses (18AWG at the tail, 20AWG at the driver) and the light was good to go. The stock 20mm Lexel driver is a fine FET+5+1 type, and the stock switch is a nice fat Omten one.
It took me 2 hours to do this mod (but the led was already reflowed). I’m not good with dust as you can see in the pics, dust does not affect performance but I should do a better job cleaning the reflector from the metal shavings that were formed when reaming the hole.
The performance is just great. With a fresh VTC6 and a clamp meter on the tail I measured 19 A. The output at startup is 4300 lumen (corrected to maukka calibration), at 30 seconds the output is 3950 lumen (just 8% drop) and the throw 118 kcd. After 2 minutes the head becomes really hot and a stepdown is desired.
It is refreshing to have a compact light with so much output that is not a flooder but a potent thrower 
. Only the SBT-90.2 could make this possible
