Not sure how long this will last in reality but it has a good level of incremental reductions in power. I use it for commuting and the light is good, has a remote on off as well if you're arsed about that sort of thing. There's also a 1700lm version on wiggle for under a ton, too.
Ah yes, I forgot there's a little thing at the back to release the battery pack. Hadn't thought about that to be honest, but I can see how it would be very handy.

There's a breakdown of the power modes/run times here: http://www.moon-sports.com/product-page/meteor-storm
