I have a 5000 lumens lamp that run on 4x18650 battery pack. I can go for 4-5 hours between charges and I always carry a spare, full charge battery pack and I also carry a 3000 lumens lamp that run on a 2x18650 battery pack. So all is well for me but I have a question for those who are familiar with dynohubs. Is a dynohub able to power a 5000 lumens lamps? What is the max output of a dyno hub?
