I'll try to do a direct comparison between the Ra Clicky Tactical (140) and (170) when I receive it. Gotta say this is the first EDC I've bought that I feel completely comfortable putting my faith in. I've been running with a Gladius Night Ops for almost three years, and bought dozens for EDCs, but nothing throws out enough light in the Strobe to compete with the Gladius. On paper they all put out much more lights, so it must be down to reflector shape and size. The Ra Clicky is the first to perform as well as my Gladius. I put some of that down to the narrower beam which has less light spill (important with a small diameter reflector). Also the weight of the Ra Clicky is reassuringly heavy in the hand. No need to worry if it got dropped, or came into contact with someone during a struggle. All I can say is I'm glad to retire my Gladius Night Ops for a smaller form factor with equal or better performance.
