The nice thing about the Ixon Space is the adjustability of the power from 10 Lux to 150 Lux in small increments. I had estimated that 80 lux is what I would need riding solo, this would last around 4 hours on a single charge on a medium setting and 2 hours on high. But if riding in a group, you can use a very low setting in the group and then turn the higher power on when at the front, hopefully making it thru a night of riding. The very modest internal battery is only 18 WH. For reference, my external battery powering my Fenix BT20 is 78 WH (3S2P).
The Nitecore NB10000 powerbank is only 5 oz and might be enough supplemental juice for a 1200k depending on how much night riding and power levels. I would slip it into my handlebar bag with USB cable to the light
