Continuing my obsession with the FW3A, this is my second FW3A Lume1 + AUX upgrade.
My favourite EDC hanklight is an aluminium KR4 with 4500K dedomed 519As and a boost driver. With this FW3A mod, I wanted to upgrade an aluminium FW3A to equal these features and give me a modern FW3A for EDC. Therefore, this one also had to have 4500K dedomed 519As. The Lume1 driver was sourced from an FW3X and upgraded to Anduril 2. Only thing missing, from my point of view, is a stainless steel bezel. As soon as I get my hands on one, I’ll be adding it.
I love the size and weight of the FW3A and having one with my favourite 519As, AUX and an efficient driver puts it solidly back in my pocket for EDC.
I chose a grey FW3A host to match the grey 1+7+FET Anduril 1 light I already have. The photos show both - oldskool and newskool together.
The only way to tell these two apart when they’re off is by looking closely and noticing that one has a glow gasket and the other has an AUX board behind the optic:
When the AUX are on, it’s easy to tell the difference. In this photo, the AUX lights are a green+blue mix, although with the default resistors on the AUX board, it’s closer to being green than being cyan:
Changing colours shows off the RGB AUX, which shows we have a Lume1 driver in:
Oldskool with 1+7+FET and Anduril 1, newskool with lume1-fw3x 3A buck/boost and Anduril 2:
Red is nice:
Green is too bright, really…
…and blue is a bit too dim, (causing the very green-like “cyan”):
