I'm going to upgrade my commuter light from a Shimano dynohub/Planet Bike Blaze LED system. I have a Schmidt Nabendynamo built into a wheel already, but what headlight to use?

My commute varies from a trip down the center of an Interstate (that's where the bike lane is) to unlit neighborhood streets. With my old eyes, I'm having issues adjusting to low light levels, so the more light, the better.

I can get either of these locally:
The Light On! DynoLight: http://www.lightonlights.com/dynolight/
Supernova E3 Pro: http://www.universalcycles.com/shopp...s.php?id=35867

Has anybody used both of them and can give a reasonable comparison? Failing that, any guesses based on their advertised specs? Are there other LED dyno-powered lights that I should consider?
