That is an extra 0.6 Watt, not volt. There are a couple of dynamo headlights that can use the extra juice. The Light On and the Supernova E3 Triple for sure. Both actually use more than 3 watts as they do not reach full light output till about 18 to 24 MPH. At that speed, depending on load impedence, a hub dynamo can be putting out a lot more than 3 watts.
My Supernova E3 Triple instructions actually note that installation of the E3 taillight will reduce the light output of the E3 Triple headlight by about 10%.
