The thing is - I've 4 Dinnotte lights and 2 Light and Motion lights. They range from $100 to...I don't recall exactly, $400? $600? The problem is - the beam patterns are usually "sufficient" for riding at night. But for actually being able to see? My Cyo (my dynamo light) is about tied for the #1 spot vs using both my Light and Motion lights - the Seca 900 on high, and the Seca 1400 on medium at the same time. They both have their ups and downs - the Seca combination will blind anyone coming towards you. That's 1600 lumens, 750 of which is with a specifically wide angle lens. The Cyo on the other hand, specifically doesn't blind anyone - including pedestrians and other bikers on the MUP I ride. It doesn't affect my night vision (I ride in a city, the trail is unlit but you get ambient lighting), so my eyes still see more - something no other regular beam light does.
For $130-$140, you can get a battery version of the Cyo Premium, same shaped beam but no additional dynamo cost required.
I have no interest in claiming that the dynamo or battery lights are superior to one another - they both have their advantages and disadvantages. Cheap china lights are undoubtedly cheaper at $16-$50. They're also less reliable, there's a little more worry about the battery overheating while charging because it's so cheap, they don't seem to be waterproof, they're more likely to break, etc.
For around $100 you can get a well made, waterproof, american light with a decent beam pattern - still cheaper than the dynamo.
With the dynamo, you get a worry-free light. It's never accidentally left at home when you needed it (happened to me). You never forget to charge the battery (happened to me). You never charge the battery last week, but the light drains it even though it's off because you didn't realize you had to disconnect it (happened to me). You never have your lights shut off in the middle of the ride because your batteries got old and don't hold much of a charge, without warning, leaving you in the middle of an unlit bike path (happened to me - luckily the moon was out). It's totally waterproof. You battery life doesn't go down when it's cold outside, or go into low power mode because it's cold. And of course - you never just plain end up on a ride that's longer than your battery life.
And of course if you're touring, you may not have the possibility of recharging light batteries at all, and a dynamo lets you charge other small items like a phone.
They both have their advantages and disadvantages. Niterider sells a $560 mountain bike light. Light and Motion sells a $500 battery light. I see full carbon bikes all the time, and those start at $2,000. It's like iPhone vs Android - there's plenty of reasons to go with one or the other, neither is the "winner" or has a clear consistent advantage.
I use both systems extensively, you said many things that have been said before and doesn't need repeating, you are also overexaggerating the benefits of dynamo system greatly.
The second set of links was definitely better...wish there was more info out there on them. All dynamo hubs put out the same amount of power - the differences are in efficiency (which is for a very small load to being with anyways, etc.
Intelligent Design site is really cool. The guy from the site is really helpful and responsive on e-mail.
I purchased the Herrmans H-Track tail light and the Herrmans H-One S head light from them for my first dynamo set up (the result of my original post)

While I don't have any other dynamo lighting experience - I have used a decent amount of headlights and tail lights over the past few years - and both of these are VERY bright. This video I made shows it somewhat - but I feel very confident riding with these in the dark. (The blinking light is not one of the dynamo lights)

Shimano 1.5 watt hub out there. I don't doubt there are other non-standard designs out there as well.

Sorry I missed your point, Paul. It is a valid one.
BTW, there is an even wimpier Sturmey dyno, 2.4W. Be careful when purchasing discount Sturmey dynos, some of the 'bay offerings have been the 2.4W version. The very old steel Sturmey dyno hub is only good for ~1.8W.
Here's a website with good info on how extra power is pulled from the better dynos:

Technically, there are other dymamos out there somewhere that put out different amounts of power - don't buy them. :-)
