I could also attach an ANT+ speed sensor to that bike to measure speed and distance at the wheel instead of relying on GPS.

My concern with using the dynohub wheel for testing the Magnics is that...

Fair efficiency test (Magnic vs dynamo)

So all the skepticism of the Magnic Light's efficiency has me wanting to devise some reasonable and repeatable test. This is what I have come up with so far. If you find issue with it, please let...

First of all, I've stated more than once that I too would love to see numbers. And second of all, it's no secret that the Magnics produce less power. I clearly stated that in my review, and...

You don't need to suspect anything. Dirk has stated as much, which is why he puts such an emphasis on the efficiency of the LEDs he's using. That isn't to say another manufacturer can't (or isn't)...

Added my Magnic review
