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.
