The SC600w MkIV Plus is just as bright, has a better neutral-white tint, is much more efficient, has the new (and better) user-interface, is much smaller, lighter, and pocketable. Oh, and a third the price you’re charging. 
I’m not saying the S6330 is a bad light. But it’s only a collector’s light if you really want to collect all the old Zebralight models, and not really up to today’s standards for LEDs.
Well, actually it is mass-produced. Not a POS, though, at least not by the standards of the time it was produced. But I’m not a fan of cool-white XM-L LEDs, and I have a Zebralight with that (my least favourite Zebra).
