FW1AA with RGB+reflector (lemmy.world)

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.

Excellent! Thank you so much.

So this should work for the original FW1A?? That is exactly what I need!

I guess it should. Unless the corners of the flex boards overlap with the MCPCB solder pads, since it was designed for a smaller MCPCB.

Awesome. I'll order some soon and let you know. Thanks so much!
