This is somewhat of an FYI, but..
I inquired at exposure about the possibility of charging their magnificent lights via dyno hub. Their lights are spectacular pieces of engineering and have used their "spark" model ultra racing, although with disposable batteries. Other lights in their line have a charger port. I have a commuter with a schmidt hub coupled to a lumotec light. Good, but not enough and at slow speeds, well...
Regardless, here is the response I got from Exposure:
"Hi Erik
Many thanks for your email and I’m pleased to hear you use our products. I can’t discuss too much with you, but dynamo hubs are becoming more efficient and as a result a good option for people like yourself. I fully understand the need for this type of lighting and please look out on our website over the next six months to see if anything will be released from us.
Regards
James"
-Perhaps with growing interest this could become a solid product for ultra touring. Imagine, charge while riding a few hours during the day, and then BAM! killer night power!
