My first attempt at modding was a transplant of a Lume1 driver into my FW3S: here.
In a second session, I added AUX to the FW3S: here.
Having learned how to do that, I repeated the procedure with a grey, aluminium FW3A: here.
I was quite happy with the two lights, but not completely. On both lights, the green AUX being too bright was bothering me. On both, but especially on the aluminium FW3A, the AUX wiring was a bit of a mess. Not visible, but I knew about it, so it bothered me.
So this weekend, I decided to fix things. Firstly, I wanted to try the resistor shuffle on the lume AUX boards and secondly, I wanted to redo the AUX board wiring.
While I was at it, and dismantling everything anyway, I decided to take the opportunity to reflow 4500K dedomed 519As for the stainless steel light (my favourites and the same emitters I had put in the aluminium FW3A).
After completing the stainless steel light, but before starting on the aluminium one, the improvement from the AUX board resistor swap is obvious.
Here are the two lights with AUX set to yellow (shuffled resistors in the FW3S on the right):
Here is the comparison with cyan (shuffled resistors in the FW3S on the right):
Finally, here’s the comparison with white - i.e. R, G, and B on simultaneously (shuffled resistors in the FW3S on the right):
After that, I went ahead with the resistor shuffle on the AUX board in the aluminium FW3A and also the remaining AUX boards I have waiting for installation in future mods.
I am now happy with both lights…
…including the soldering:
