Well, maybe not the X-1...just to differant of a beam. Anyway, I read the Arc is better than the Ultra...but that was in Arc land where anything Arc is praised and worshiped (perhaps deservedly so). Is it really brighter than the ultra...consistantly...or are folks comparing the two without new batts in the ultra? Why, beyond the larger/shiny reflector would it be any brighter than the ultra...or for that matter the Arc AAA...don`t these two have the same curcit?
