  • I am trying to track down the output rating for the Edelux II.

    From the SON rear light instructions mention:

    The 6V-3W hub dynamo-powered SON rear light (K 920) is made for use with a 6V-2.4 W-LED-headlight or 6 Volt DC supply.

  • That suggests that the SON rear light is intended to take 0.6W. I think the RedEye is 1W. Trouble is, there's nothing I can find which explains whether there's any current limiting circuitry in the Edelux rear light supply and, if there is, what it's rated to. Or, indeed, whether the rear light supply has any power rating limitations or whether, if you wanted to, you could chug the whole 3W down to the rear light.

    There's one way to find out, of course, but it's a bit depressing if the answer isn't the one you were hoping for...

  • I've emailed Sinewave (as they've solved this problem with their light) and Exposure to see if I can get some more details. I'll get round to contacting SON in a few days.

    If that all comes to nothing I'll break out the big multimeter and go ride down some hills...

  • I can confirm you can't wire the son rear direct, would seem it have zero protection. Two none functioning lights would confirm. Yes I am a moron that was slow to work that out.
