FW3A, a TLF/BLF EDC flashlight - SST-20 available, coupon codes public

I did think about a lighted tail, would be Difficulty Rating-9+ I think, but possible.

The MCPCB issue was bothering me so I swapped in a Noctigon and applied decent paste, also changed the driver wires to 20AWG.
Here’s how the stock compares with a noctigon.

Stock MCPCB 1.45mm thick
Noctigon 1.72mm thick.

I would recommend changing the paste and lapping the MCPCB in these if you can.
