I had a Luxeon 1watt flashlight, thought it was really cool, bought a Fenix L2T 3watt Luxeon, blew my mind how much better it was...lights up trees down the block. In my opinion, the L2T's batteries are better than the Inova...it uses AA's instead of hard-to-find 3volt CR123 batteries(at a fuel station at 3am when the Inova's are dead). I use 2500ma rechargeable AA's in mine.
My friend just bought the L2D on my recomendation, it's soooo much neater...the L2T does 10 lumens for 16 hours and 55 lumens for 2.5 hours...the L2D does 9 lumens for 55 hours, 40 lumens for 22.5 hours, 80 lumens for 10 hours, and a whopping 135 lumens for 2.5 hours...it also has a really fast puke-inducing strobe or a 3-flash SOS mode.
Sorry about the thread hijack...nobody but Bill Gates is gonna spend $46-$56 on these flashlights for use as rock lights, but it's amazing how bright they are, and how long the batteries last. A guy could do worse than get one of these...i use mine instead of a drop light when i'm working on my Toyota's, they last so long. Imagine going 4x4'ing on a rough, BFE trail and rolling down into a ravine. You're trapped and can't get out. The fast strobe mode is really noticeable at night...even if nobody is searching for you, someone will probably notice it, and it'll run for days or weeks.
