this combination is great. I highly recommend it, even though i prefer the edelux for city riding with ambient lighting since it is focused on the road surface, it seems brighter. For truly dark rides, the e3 provides more overall illumination (sides of roads etc), in addition to an incredible taillight.
one apparently cannot connect the supernova taillight to the edelux, or the iq cyo etc. (without electrical jerryrigging).
edit, this info is from peter white, and gregor arndt at supernova. I have not personally tried it...yet
He's the one who gave me all the info about wiring dual E3 lights on my SON28; I trust what he's got to say.
