Does that mean it is safe to use Simon’s copper MCPCB with the 519A in a SC31pro? I think tailcap current was measured somewhere at 6.7A (haven’t measured myself, and definitely didn’t take it apart to measure current to the LED but that is likely the same unless it’s a buck driver. Datasheet spec is 6A max on the SST40 so I suspect Sofirn won’t let it go much beyond that).
Secondly, generally the datasheet values look to be very conservative, also with the SST20, which is stated to be max 2A or 3A depending on datasheet. However, it is driven much higher in many tests. So could I take Simon’s copper MCPCB with SST20 4000K and use it in a Wurkkos FC11? (where it is driven at 3.7A as I read in one review) and will it last or will the LEDS not last long with these high currents?
I am curious about this as I don’t like the LH351D in the FC11, it is not bad, but something just feels off every time I use it. For general use I would even prefer the lower CRI XPG 5B1 and XML 4C I have in other torches. I have an IF25A with SST20 4000K and that is just perfect in light colour (for a work light), where nothing feels weird at any time (in any situation with different coloured objects), so I’d like to install that in the FC11 (along with a TIR to give a wider beam). I am curious to see the 519A in action too and compare it to the SST20.
