Arc -- Brighter, smaller, only 5 hours run time
Infinity -- Dimmer, larger, whopping 40 hours run time.

OK, first understand there are a lot of factors with the run time, but I did a side by side constant on comparison of an ARC-AAA and infinity. And the ARC was started out much brighter and was about the same brightness 12 hrs later. At hour 13 it was slightly dimmer and I turned it off shortly after that.
The
arc website has some good info on battery life, but Peter is being very conservative run time wise, compared to the competition, the 5 hrs is for full brightness, it actually lasts much longer.
One of the competition says they get 70 hrs of "useable light" with 4 LEDs off 3AAA batteries then when you read the fine print it goes something like this:
" ** Definition of usable light: enough light to tell the difference between your arse and a hole in the ground"
I like LED lights, but I hate the way some of them are advertised.
Thumbs up for Petzl for putting a graph on the back of the Tikka package showing how the brightness is 1/2 after 12 hrs and about 1/20th at 150hrs.
