Output Notes from Shutter Precision
The SP-9 Series real output is 6V 3W for 20”, however for 26”/700C its output is very close to 6V3W but still a little bit less at low speed & therefore, it cannot pass German StVZO regulation. For the German market SP must get StVZO approval so the 9 series was used to apply the new regulation i.e. 6V 1.5W LED. And 9 series got 6V 1.5W LED StVZO approval.

What Spoke Length Required For 26" Build ?
29 Jul 2015
Very interested in the SP SV9.
What spoke length is required to build this into a 26" wheel or is the flange diameter such that it should swap out for a standard hub ?
Also what comes in the box (cables etc.) and what lights do you stock that are compatible (front and rear, connectors etc.)

The spoke length varies not only with the type of hub fitted but also depends on what rim you have fitted. The only thing supplied in the box is the connector cap that you fit to the end of the cable. As a suitable end cap is supplied, nearly every dynamo front light will be compatible with this hub, some may just require a small amount of adjustment to the cable to fit in the supplied connector cap.
