Good source for HX-1175B? I cant say for certain. Check this thread. One source (from aliexpress) mentioned in that thread seems to advertise HX-1175B, but ships out a less powerful HX-1175C. Maybe ouchy had a good link? Again see that thread.
I actually down adjusted the current of my HX-1175B to 6,4A in order to be a bit safer, some info here.
About lux. Nice you asked about the ZY-T08 and not any of the others, because its the only light I have measured. :D
202.000@ 1 meter with a lux meter that reads lower than most/many and no AR lens. Measured at 5 and 10 meters. If I add a calibration value that would get me closer to people with higher lux readings (which seems to be owners of LX-1330B lux meter) I should be looking at around 230-260kcd.
Getting comparable lux values with other members with different lux meters is really hard. Especially since the readings can vary a lot between different lux meters. Im trying to gather some useful info on stock Convoy L4 lights in this thread just to see what differences people see on their different lux meters.
