NiteFighter F30B - Any reviews of it?

I got one of these in on a good price from BangGood, US warehouse. It's a nice quality light overall for the price. Head diameter is slightly wider than an X6 or D80, but has the wider I.D. reflector, like the D80 has, maybe 5 mm wider than an X6, so it's theoretically a better light for throw vs. an X6.

Couple things:

  • Mitko mentioned here: https://budgetlightforum.com/t/-/33641, the body tube is glued to the head, but on mine, that's not the case - came unthreaded easy, but it's beefy driver retaining ring seems impossible to budge. I hope it's not reverse threaded because if so, I really tightened the heck out of mine then. At this point after working on it for a while, I think there's no other choice but to start drilling/cutting it off.
  • the MCPCB appears to be a non-standard 25 mm size, but might be able to fit a MaxToch 26 mm in there.
  • the lumens readings are sub-par at about 500-600, but throws pretty good for such a low lumens output, think about 20 kcd. Id suspect an XM-L2 T6 at best, maybe lower
  • tail readings are about 2.6A on a good cell
  • It's got a long reset time to start back at mode #1 (hi), like 20 secs or so. Any sooner clicks will be next mode
  • the tailcap threading doesn't appear to be square but they feel like quality threads - smooth

If anyone else has this light and attempted to get to the driver and/or did any modding, please post here. Thanks!
