As another alternative does anyone have experience running these modern dynamo light systems on dc batteries? I'm looking at the iq cyo premium and toplight line-plus.
My understanding is that dynamo hubs actually generate a/c, so you can't run them directly off of dc current.
Sometimes they make a dc current model for electric bikes.
But there's no real reason to do that as nowadays they also sell battery versions. The Ixon Iq Space is B&M's version:
B&M Ixon Space - cutoff, built in lith-ion battery, 150 lux (not lumens)
The Lupine SL A4 is a brighter light with a cutoff and an external battery pack:
B&M Ixon Space - cutoff, built in lith-ion battery, 150 lux (not lumens)
