First off, both the manufacturer of the light and you were based Spokane WA. That was the 1st clue.
Second, you wrote that you were using a FET+1 driver based off of an Atiny controller. That was the 2nd clue, and the proof that the manufacturer was on BLF.
Third, I saw something interesting. You wrote about using silver-plated BeCu springs. I then searched for BeCu springs on BLF, which yielded mostly my thread results, and then I saw this post specifically mentioning Beryllium Copper springs: https://budgetlightforum.com/t/-/38876/126
I then connected the dots, and realized that it was actually you who started the Kickstarter
Nice light BTW. I would have loved it if you could use a boost driver though for NiMH compatibility. Although there are not available boost drivers in the BLF variety.
