imho the main prob with the TT is that in trying to do 2 things (ie incandescent & LED) it really doesnt do either one very well, if ya want 2 diff brightness settings try one of the new fenix lights with the switch to change brightness, or a SF aviator, or one of the SF LEDs thats adjustable, any would be better than the TT imho, not that the TT is bad mind ya, its just not very bright. if ya dont need that it might work for ya, but a tac light its not.
