So, bought H200 for modding. Since i dont need red light decided to make a one channel triple swap leds and driver. Here some head pics:
DC converter marking are erased…
Head is empty, it have thin shelf for mcpcb and that is bad for heat dissipation

Well, but it have good 2+1 cooper mpcb with direct thermal patch. Swapped leds to 3500K, shorted pin and now it is simple triple.
All back in place.
Beamshot comparison to Convoy S2 with 60degree TIR:
With custom buck driver full turbo available down to 3.1V and theoretical +25% eficiency. Setup works like It is boost driver.
