I don't EDC my LX3.0, but if I were to carry it around all day long, I would imagine it to be in a bag or a holster.
Personally, I think it's size is fair, considering it is a three cells light. /ubbthreads/images/graemlins/smile.gif If you want LED lights with a similar build, I would recommend Gerber Trio which, IIRC, is shorter and longer runtime.
