Hey Brightnorm,
I have both the 8AX, and a brand new polystinger. The stinger wins hands down except for beam quality...and that is a VERY close contest with the stinger on tight focus.
I get the full advertised hour of run-time out of my stinger, and if I charge the 8AX batter overnight, I might get 20 minutes on a fresh battery.
I have spoken with SF CS several times regarding this and gotten the runaround every time. Last I was told was they were having their chargers re-engineered by another company and that the batteries were fine...now I find out it's going to be 10 weeks (which translated into SF time who knows how long) before new batteries are released which should solve the problem.
(Talk about run-on sentences!)
The 8AX is a beautiful light if it just worked as advertised. I would like to see a metal stinger, stinger HP, and ultra stinger but for the money, 79 bucks, I couldn't pass on the poly.
Don't waste your time on a SF rechargeable until they start getting rave reviews here.
