I got the xhp50 yesterday. It rocks. I can not believe the output and the throw.
Better throw than the Convoy L6 or the S70S
More PERCEIVED light than the Q8 or SP36
scosgt and BlueSwordM thank you guys for sharing your experience and opinion 
but it doesnt hold up heat very well or ? atleast the l6 i can run turbo almost nonstop and its not that heavy when i touch the head… i think the ft03 is better have the sst40 version and u get better throw and less heat.
Heat is not the issue. The major issue would be battery drainage the FT03 would last less than half the time of the L6 or S70 at max brightness.
Is the 3v xhp50.2 a direct swap for the sst-40 version of ft03?
Yes it is. Xhp 50.2 also has same footprint as sst 40, so you can even reflow it to the existing mcpcb yourself, if you have sst 40 version
Is there a stateside vendor with competively priced FT03 with XHP50.2 ?
Newbe question: is there such a thing as an XHP70, and if it does exist, what would
The difference be? 
Halal snack pack?
I see HSP and that’s what I think 
sorry, getting carried away.
XHP70 and 70.2 definitely exist, and they’d physically fit in the FT03, but the issue is that I believe they’re mostly 12v. There’s apparently 6v variants, though. Compared to the 50.2, it’s the same kind of “wall-of-light” profile, just bigger.
Thanks for your response!
Acronyms bring out the dyslectic in me. 
No worries! I always just imagine it’s “eXtra Heavy Photons” 
Does the 50.2 have the same FET driver as the SST40 version?
Hey mate yea the same driver.
This XHP50.2 is a 3v variant.
I haven’t been able to find a stateside vendor for astrolux flashlights. I would like to see one.
Banggood will get it to you in around two weeks.
I prefer the earlier (less lumins) version.
It has much longer throw.
But both are well worth having.
Does this require a 3V 50.2, or will a 6V work?
I don’t find any 3V for sale…
Does the 6V work?
