I feel like a broken record - I should just put the dang thing in my sig.
Try the Terralux Lightstar 2 x AA if you want 180lumens in a no-wire setup. Runs for 1-1.5 hrs. Every bit as good as a Fenix. Mount on helmet with a rubber band or use a $5 Twofish lockblock on the bars. Drops into your pocket when you're done. $28 per light. Get two and you're good to go for front lighting in the vast majority of situations. (Probably not fast trail riding, but the helmet light option is really good, even if you have a Magicshine.)
But the magicshine seems to be the it-light for BRIGHT applications.
