I got this info from Sofirn too from Aliexpress. I hope I’m in the testing team 
I wrote my suggestions to them at there. Mainly I suggested them to move to make a different kind of light like a triple led tube form 26650 light or something else because this is very close to Q8 but Q8 is on sale months ago. This could be a good light because the UI is pretty good and I hope there will be a lot mass in the head but Q8 mostly filled the requirements for this type of light.
