Here are the before and after numbers.
Note: lumen tube numbers are elevated slightly from inaccuracy of my lumen tube.

The end result was very good. It runs much cooler and longer. The beam downstream was no comparison.
No mod to driver or batteries, the only difference was the reflector and heat sink.
.
A deeper reflector does make a difference in throw. It throws better than the Buffalo with the same reflector at 1192 meter using a Lexel driver at 12v 6a and a XHP 70.2 with 9000 lumens. Proof as stated at Aliexpress that it was made for a SBT 90 led.

Here are the dims for the reflector if someone wants to do this mod. It is not too hard to do on a manual lathe like I did.
The threads in metric are 64mm x 1.0mm or 2.519 x 25.4 tpi ( I used 26 tpi on my lathe ).
Turn the diameter to 64mm ( 2.519 ) and 37.4mm ( 1.472 ) from the small end of the reflector.

Here are the dims for the bezel, no threads.
PM me for help with the bezel, mounting it was tricky, but not complicated.
