I use the Schmidt Hub and a 3w Supernova LED and am very happy with it. It works well and I like the LED more than the E6. No bulbs to fiddle with and the LED light I have is a lot less fragile. I boke an E6 lense/housing in a minor crash. Also I had a weird issue when I ran 2 E6's toghether. The Primary light was not as bright as the secondary. I changed the bulb twice just to make sure. When I called PW, he was not real interested in helping me figure out what the problem was. I got the Supenova from Germany and it has a nice easy to use switch (even with gloves" and is about 3 inches long x 1 1/2 inches wide. I mounted it on my non-drive side fork blade. Nice beam with a little more spill than the E6.
