Thanks for the info. BTW, nice beamshots in your sig-line link. That Thunder put all your lights to shame including your mag mod!!Firstly the Thunder, I have settled on 2x cells maximum in my lights, easier to charge two than three. About the Fox, different to the Sniper, when focused the centre area is brighter than in the Q5 Sniper and when set to wide, the change from centre to spill is more gradual, more like a flood effect. If you like a smoother flood, the Fox set on wide is better...that's how I like mine.
