I guess I'm used to incandescents, so my X5T's light appears to have quite a blue tinge to it.
The light is acceptably bright for most nighttime tasks, anything long-range is handled by my Surefire.
I also agree that the tailcap sucks, and the lack of a clip is VERY annoying. That "tactical sheath" is next to useless, since it wobbles around on the belt and slides around when you try to pull the light out. So I just carry my X5T loose inside my pocket. My phone is getting all scratched up

The lanyard hole's edges are a bit sharp, they'll probably cut up my paracord lanyard in time. Smooth aluminum body, even with those grooves, mean that the light is very likely to slide out of wet hands. Brilliant "free-roll" design makes it way too easy for the light to roll off a surface. Not very tactical if you ask me.
But... I still think this light looks damn sexy. Stare down the 5 barreled silver end. Ooh. Feel the grooves at the tail end. Looking at it gets me all excited. Uhh, I think I'll stop now.
Summary:
Tactical? Nah. Sexy? Yeh!
Buy it if you like cool gadgets, but not as a primary light.
