The hub dynamos are not only compact and lightweight, they're more electrically efficient than ever. Especially the new hub dynamo DH-2R30-E generates 30% lower rolling resistance than HB-NX22 (when lights not in use). A sensor switch (SW-NX30) can be used to turn the lamp on and off automatically according to ambient light levels.
