Yeah, the Q5's.
Anyways. My Fenix alone was brighter than a Cygolite Dual-Cross 300. Food for thought.
I picked up the Cree Q2, which is brighter than the Fenix, and paid $25 for each one. $25, + the mounts, and you get an all in one thing, and you don't have to strap a battery anywhere, and it will be brighter than the $250 Cygolite Dual-Cross. If you pop in an 18650 battery, it will last 3.5h, the same duration as the Cygolite. Add a second light to the handlebar, and mount one to the headtube, and get a $20 Cree Q2 ultra bright for the helmet, and you will be packing some serious heat!
