I recently got a stainless steel FW3A from JLHawaii. It came with an old, original, 1+7+FET driver and Anduril 1, so I decided it should be modded with a more efficient Lume1 driver and Anduril 2. To get hold of a Lume1 driver, I had to get hold of an FW3X.
The FW3X came with Anduril 1 installed, so the first step was to upgrade to Anduril 2. Problem was that two flashing pads were the wrong way around, so I had to modify the pin layout on my Hank flashing kit to be able to use it to flash the FW3A Lume1 Anduril 2 hex.
After unsoldering the various wires, I was able to remove the Lume1 driver from the FW3X and the 1+7+FET driver from the stainless steel FW3A.
I wanted to add a Lume1 AUX board, but unfortunately I managed to damage the red AUX pad on the Lume1 driver board, so that it was impossible to attach a wire to it. Therefore, the stainless steel FW3A mod is only a driver upgrade without adding AUX. It was very, very fiddly and took many hours, but I finally managed to get the Lume1 driver installed in the stainless steel host.
Put back together, it all worked and now I have an efficient stainless steel FW3A.
I also had an aluminium FW3A with a degraded driver (Lumintop put in an inferior driver in later production runs), so I decided use the 1+7+FET driver left over from the stainless steel light to “restore” the aluminium one to a more original condition.
