I know most of us here carry AT LEAST 2 lights most of the time, but recently I've had hankering for a be all, end all light with easily manipulated multiple brightness levels. That way, you don't buy more lights, looking for the perfect one for this or that (yeah right /ubbthreads/images/graemlins/wink.gif), you just buy more of one type of battery (or use rechargables). I'm not sure this ideal light exists yet- most are too big for me (Streamlight 3W 2L, U2) or have fancy UI (HDS) and in practical terms, maybe its better to have, for example, one bigger momma and one little guy- you have totally seperate systems in case one fails. Also, with multiple lights, you are more easily able to cheaply find lights that excel at the one thing they do (ex. T1 for bright throw/Arc AAA or Ultra-G for close-up and spill). However, there is a certain appeal to having one go-to unit that can do everything- less to keep track of in your pockets, etc...opinions?
