My buddies and I do a lot of night riding in the hills. We're always comparing lights and borrowing/lending different kinds to find out what kind of brightness would work best for us. There's always a trade-off for brightness = weight = battery life = cost and it's hard to judge what someone would need by looking at a catalog. Having different kinds of light samples would be very helpful.

I like to use a 200L Dinotte for street riding (only 200g!) and a Niterider TriNewt for some hillwork in the dark. I've also chased someone down a twisty descent at night - he had a Moab and that thing could light up the side of a mountain.
