Using LGHg2 batteries (10 amps) and acebeam protected 3100 mah batteries:
All performs stats seem to be on the mark compared to standards I use.
Excellent high-output thrower. This is the smallest I would go with the Sbt90.2 LED, large carona around the hotspot. The light is nicely portable, but not coming with a holster holds this light back. Mode speration is perfect, you can tell it's getting brighter with every step change.
The turbo can still be (briefly) accessed well down to 3.3 volts per battery, which is good to know. The light gets hot but includes a handle to prevent hitting your hand. The far output is really amazing to see and use.
There isn't a roll stop so be sure to use the handle if you want to set the light down when being used. The light is well balanced and has an amazing detail to the knerling which helps grip, and the size is perfect for one hand.
Only thing I'd change is a holster. I had to improvise in order to take care of it.
