From what I can see on the website, it's 6 V total, with typical setup being 6 V 2.4 W front, and 6 V 0,6 W rear (or a single 3 W headlight, no taillight). And from what I see, it looks very much like one of the Shimano dynohubs, which lets me think that both might be made by the same manufacturer and simply branded differently.
It would therefore work with Peter White's dynamo lights.
One word of caution : not sure if the dual headlight setup would work.
