Default Pros and cons of dynamo hubs & lights?

Hi,
I want to put a drum brake hub into my front wheel and was contemplating building it with a sturmey-archer drum brake + dynamo hub. I've done some reading but am still undecided about the dynamo. What experiences do people have running lights from dynamo hubs?

I've had a look around at various dynamo lights and my concerns are mainly the cost of the lights themselves. It seems the cheaper units don't put out much light and then there is a sudden jump to pricey units that do put out a decent light. Tricked out lights with leds and storage for when you're waiting at the lights. I'm talking $150 australian PLUS for something that cranks out enough light to ride safely along an unlit path.

But then I think well if I use it a lot maybe it IS worth it compared to the price some of the battery driven lights which can be very expensive themselves.

Thoughts/comments/observations?

Cheers,
Dave.

I went with the Sturmey Archer drum brake & dynamo hub but as I've not completed the Rollfast build yet I can't give ya a review lol

I do have my concerns about possibly burnin' out the gen with the constant "high speed" usage on an MB... but TBH the cost I shrugged off as I figured it's my brakes too and it's just too tempting to have a nice, steady source of power for lights & small batt charging to not give it a shot

Has anyone used wonderful creations lighting system?Will it burn out C.D.I.or Stator faster? In Minnesota we have to have a D.O.T. legal lighting system to get it registered.Is this what I am looking for?

If you look at that Wonderful Creations system, it uses an additional magneto for the lights. So you're running the ignition off the stock mag, and the lights off the aftermarket mag. It's a neat looking setup, but seems pretty pricey to me. (Note that I do not own one of these.)

I was wondering if that extra magneto(from Wonderful Creations) would draw too much from the magnet and then it would eventually die out or steal from the CDI current. I know that some of these magnetos/magnets aren't fully charged or lose their charge on their way across the pond. Anyone had those type experiences???

When you turn a magnet near a coil of wire, a current is induced in the wire. This converts kinetic energy (turning the magnet) into electricity. The magnet does not lose magnetism, nor is its inductive property somehow "stolen" from another coil.

Thanks Nougat, I was afraid that it could wear down over time, now I'll give it a second thought for my lighting system.
