Note that SV9 hubs are now labelled as 6V 1.5w. This is to comply with the strict German StVZO regulations. When used with 26 inch or 700c wheels the output can drop very slightly below 6V3 W at low speeds, but is 6V 3W at normal riding speeds. For 20 inch or smaller wheels the output is 6V 3W. The hub is suitable for all lights or accessories designed for 6V 3W hubs

If your're interested in the detail:

"From wheel size 646mm(26 inch) to 716mm(700c):
According to German StVZO, it requires 3V output at a low speed of 5km/h. If the 9 series is set on wheel sizes of 646mm(26 inch) and 716mm(700c), it offers 3V output speed at 5.8km/h and 6.4km/h respectively. To have 3V output, it only needs to slightly increase speed up to 1.4km/h. Furthermore, according to German StVZO 6V3W regulation, it requires 5.7V output at 15km/h. If we set the 9 series on wheel sizes of 646mm(26 inch) and 716mm(700c), this 9 series offers 5.7V output when speed at 15.7km/h and 17.7 km/h respectively. To have 5.7V output, it only needs to increase speed up to 2.7km/h. As for 6V3W, the German StVZO approved hubs in the current market normally offer 6V3W output when speed around 17km/h. The SP 9 series offers 6V3W output for 646mm(26 inch) and 716mm(700c) wheels when speed at 16.7km/h and 18.6km/h respectively."
