My next project is to build a wheel around an SP PV-8 dynamo hub and get a dynamo headlight that can co-exist with an Ortlieb handlebar bag on a Surly Long Haul Trucker. From what I see at Peter White's website, it looks like all of the German dynamo lights can do so. That and having USB voltage conversion will definitely make this worth spending the extra money over something like the Planet Bike Blaze Dynamo.
The Luxos U is the only Busch and Mueller light that does usb charging, yes. There's another dynamo light from another company on amazon that does it, but despite similar looking specs the beamshots and people's comments suggest it's a very poor light compared to the Busch and Mueller lights.
For the same cost you can buy a light that doesn't do usb charger, and add on one of the several usb-charger accessories for a dynamo that do the same thing but are not integrated into the light.
Also agree that the Planet Bike dynamo is far worse at throwing out light than Busch and Mueller offerings. It's only advantage is if you only need a "to be seen by" light in the front, as it has a blinking mode.
