Having dynamo lighting is absolutely awesome. It might initially seem less powerful than a mega-lumens battery job, but it's focused where it needs to be and is plenty bright/strong enough for being seen. Son Edelux II is great, and I think the B&M is very good too (a few models to choose from - they nearly all do have a standlight but you definitely want a standlight). Took me a while to hook up a rear dynamo light, wish I'd done it ages ago.
The Edelux II and I'm sure other models can be switched to light sensor mode, so they aren't on in daylight, but come on when light levels get low, i.e. tunnels, dusk, night time.
