Boy this thing is Awesome! Yes it is greenish on moonlight but loses that on all other levels.
Bought one for a friend and opened it up to check it out so got one for myself also.
Fantastic little thrower makes my Weltool T1Pro look like a ts10.
I have tried many Wurkkos lights and was not impressed with any as they felt cheap but the TS12 with Skilhunt M150 clip is sweet.
