I don't know if they make them anymore, but I used to see 2.4 watt and 3.0 watt dynamo hubs. The 2.4 watt model was supposed to be for a light up front. And the 3 watt model for a 2.4 watt light at the front and 0.6 watt light at the back although I read if you pedal fast enough, a 2.4 watt dynamo hub should power two lights anyway.
According to Shimano documents I've seen, some dynamo hubs require the SM-DH10 overvoltage protector. Some models may not require the overvoltage protector. And from what I've seen on the bike24 web site, the LX dynamo hub has serviceable bearings. Usually, they say not to touch the bearings at all because if you break a small piece of metal inside, it may stop working.
Busch & Muller is known for their dynamo lights. The Lumotec Lyt is cheaper than the Cyo but the Cyo is more powerful overall and has a more powerful standlight (temporary light when you stop pedaling). I bought a Lyt from xxcycle from France but haven't tried it yet.
