This is where I checked: Driver Info: HX-1175b & HX-1175B1 (Pic Heavy)
Reading it again it seems like the b (not b1) is for SST90 3V leds. I guess the B1 or C models are for 6v output only nvm I was wrong, it works for 3v
.
I hope some day MTN electronics gets buck drivers that can do more than just 6A on a 3v led…
