i had one some time ago. if its from the limited run offer. it uses a xp-g 3000k warm tint LED. its not the same as the 90+ high CRI 3000k XP-G. the tint on mine was a little more pinkish than the high cri xp-g when comparing side by side. something thats probably unnoticeable by itself.
all Turbo models have the tactical 2-mode programmable interface.
throws a nice beam with a faint darker spot in the middle of the hotspot. it was a non-issue for me.
i think... the turbo threads are cut a little different than the other quark threads. i used mine with a single AA quark body, and i ran into problems threading it on. i was required to use some force, or torque. it worked fine with the clip in the bezel down position, but when i swapped its position it had contact issues in the bezel up clip position and didnt work that way. this could of been specific to only my quark turbo though, as ive had thread problems with some 47 lights and not others.
