it doesnt say "Upgraded" anywhere (neither on the body nor in the manual); since it's the "Upgraded" version anyway: mine has 3 modes and the mode sequence is:
there are Titanium version with the XP-E emitter (old production models) and with the XP-G R5 emitter (newer production models), as is stated even in the manual. So, yes, they also switched to XP-G R5 on both the SS and the Ti versions.
Lotería lotería, tu lo has dicho. Pity not to have $$$, because with coupon "oneworldweshare" and dinopints I could get it for 23$, but I want the Q5 version, not R5.
no i dont have the iTP A3 Alu .. but i do have the Lumintop Worm Alu and Lumintop Worm SS, and their heads are butter smooth to twist. You can tell the difference between the hard butter (SS) and the soft butter (Alu).
The Worm heads fit perfectly the A3 body, and vice versa, btw.
The A3 Ti head is difficult to twist with one hand BECAUSE the head sits tight. But the twisting itself is smooth, and not gritty/grainy/grinding. In any case you can help yourself by CPF methods haha.
In other words, yes, there is a big difference between the forces you need to apply Alu vs. SS vs. Ti; but in all cases it is a smooth, non-grinding feeling. And the tightness helps *not to lose* the head accidentally!!
You shouldnt worry .. unless butter-smooth one-hand operation is VERY important to you. (Typically i use 2 hands to operate the A3 Ti)
I just rec'd my stainless A3 from DD and I believe it's an R5 though I'm not positive. It is the same emitter that my late-gen aluminum A3 has. If anyone has a high res pic between the two emitters I could confirm.
The threads are definitely tighter but smooth, and the o-ring was really tight and needed lube.
The only problem with mine is that the inside of the lens is a bit cloudy, but it doesn't impact the beam whatsoever. I tried to unscrew the emitter assy from the head but it seems to be in there super tight and I don't want to kill this gorgeous light!
One friend also received a ALU version with cloudy glass, I dont know why. Yes, it does not affect the performance at first sight.
About the LED. The xpg-r5 has 4 lines (divisions) while the xpe-q5 has only 3 lines (divisions). Also the led xpg is bigger than the xpe.
Put one next to the other. If the led seems to be same size, both have same led. If one is bigger (or smaller XD) than the other, then one of them has Q5 and the other has R5.
ALSO you can distinguish which have Q5 or R5 by watching the beam they produce. The R5 throws less and has a not so defined hotspot than the Q5
