Great idea - exchangeable battery tube sizes; Something I always thought was logical for many commercial lights which seem to share the same ‘head’.
I previously detailed it here: NEW EagleTac D25C & D25A Ti - *2015 Edition* with regards to EagleTac and Nitecore, who could have done the same with most of their offerings within a model range.
Please put me down for two. Would it also be feasible to include a small plastic spacer tube to pad the more common 16340/RCR123A so they can also be used without rattle in the 18350 tube. (Similar to that which came with the NC EC11).
I’d pay the extra dollar (if even that much) which it would cost to produce and include such a spacer.
