Testing the Magnic Light Against a Supernova E3

The Magnic bicycle light (www.magniclight.com) is an amazing contactless dynamo light. It generates light through its proximity to a moving wheel.  I supported it through the inventor’s Kickstarter campaign, and as part of this received a pair of front lights and a rear light suitable for my road bike.  I was particularly attracted to the fact that with the Magnic one does not need to have a wheel built around a dynamo hub, or by being contactless it avoids the noise issue with rim dynamos. What follows is my assessment of the Magnic light, in particular its suitability for long-distance endurance riding.
