Got your PM by the way. Getting it in the mail today or tomorrow. Only light I had with a SST40 in it was a Jetbeam E20R if I remember correctly. Not sure of the tint on that one but I remember seeing a good amount of green in it. I am pretty sure it was a CW tint so that may explain it.
The Luxeon V2 is quite nice. I haven’t noticed any weird tint shifts or anything like that. If the SST40 throws like the SST20 then the Luxeon is more flood than throw. Pleasant beam. Beam pattern seems to be on par with the 219C. Give or take a pinch.
