I rented the Switchback3 for 24hr Allamuchy.
The lights were great, but a bit too heavy...perhaps because I got the biggest one.
I didn't compare 1 2 or 3, I just went for the one with more light just because I thought it was better to have more light just in case.
I didn't run them all night since I decided one lap in the storm was enough.
So I guess: Lights = GOOD, Weight = BAD
