Hello, first post here :D
A few month ago I modded a FW1AA with boost-buck driver for NiMH/li-ion and with RGB LEDs.
I used a TIR lens for the aux led to shine through, unfortunately it had artefacts in the spill that ended up a bit too distracting so I went back to the original reflector and used a thin flex PCB under the reflector with tiny LEDs that fit in the opening. I’m very satisfied with the result, plus the beam with the 519A+ SMO reflector is surprisingly good.

Awesome! Do you think if I can fit these RGB leds under an original FW1A reflector with the smaller opening (not the crappy FW1A Pro reflector)? If I can eventually find one that is.
What’s the diameter of the opening ?
Edit :
If I can eventually find one that is.
Oh you don’t have one, measuring from a picture I get 5.9mm, if that’s right then it will be very close.
I can try making a version with the LEDs closer to the 3535 cutout.
Circle is 5.6mm :
