What did you mod today?

After modding a copper FW3C with a lume1 driver and single-colour green AUX LEDs (here), I still had another lume1 driver with damaged RGB AUX connector pads. I planned to use this one for another mod with single-colour AUX LEDs.

Some time ago, I got hold of a brass FW3A and planned to mod it with warm emitters and orange AUX LEDs. My other brass lights also have orange AUX and in my opinion it’s the nicest AUX colour for brass lights. In the weeks the light has been waiting for the parts to arrive, it’s developed a nice, smooth patina, which I like better than the polished shininess it had out of the box:

For this one, I didn’t want a not-quite-orange yellow colour from mixing red and green channels on an RGB AUX board, so I sourced some orange LEDs and a lume Tri-LED AUX board to mount them on.

This was a very slow piece of work, those LEDs are tiny and the resistor even more so.

I swapped out the original 6500K XPL-Hi emitters with 2700K SST-20 emitters to give the light a nice, warm beam to match my other brass lights and put in the Carclo 10508 frosted, medium spot optic to give a floodier beam.

Finally, as for the copper light, I’m using my custom Anduril 2 build for the lume1 driver, with UI modified for single-colour AUX LEDs.

It’s turned out as well as I’d hoped it would…

The orange AUX are lovely, either behind the default or the frosted optic:

The positioning of the AUX is different with the Tri-LED AUX board (left), compared to the RGB AUX board (right):

Together with the FW3C, this makes a wonderful pair of lights:

This picture shows the difference between using real orange AUX LEDs rather than relying on the mixed Red and Green of RGB AUX:

The left-middle light is my brass D4V2 with RGB AUX set to yellow/orange, the right-middle is a PL09 Quad with orange AUX LEDs and the right-hand light is the new brass FW3A mod. On the left is a brass TS10, on which the high AUX LED setting is far too bright.
