I have had both the older XPE-Q5 and the newer XPG-R5 versions.
Differences in output are hard to spot, unless you have them side by side, and the R5 version is much more floody. In either case the A3's are great value for money. (though my edc AAA is a 4Sevens Preon ReVo)
Now that Olight is folding the itp brand into itself, you might be able to pick a deal on the A3's.
