I run a BLF Q8 with 4 18650, 12000mAh total, it has a maximum output of 5000 lumens. It's mounted on the handlebar with a camera adaptor and a strap to firmly secure to the handlebar. It lights things like a Magicshine Monteer, but with high color renderization. It's heavy and a beast! Now I'm moving to a lumintop FW4a with "only" 3600 lumens on turbo, but can sustain at least 1500. It uses just one 18650, but I carry a spare battery like Sean Chee comented above.
I do have problem with mountain bike especific lights because they generaly have their own design, the battery can't be changed on the run, and are more expensive than a good light with a good mount.
We just need a good mix between flood and trhow in a flashlight to use it at night, it needs to be robust, the battery need a good run time and be changed on the trail.
To anyone interested, there is a flahslightholic club in reddit, r/flahslight.
