Will bulbs just burn out when a decent speed is reached? Do I have to buy a specific hub dynamo, or just higher rate bulbs? I would also be very interested in hearing from anyone who has used the systems that allow you to charge mobile phones or run sat nav ect from hub dynamos.
Thank you, Ed

don't worry for bulbs burning, all modern lights are overvoltage protected so ... the faster the better.
As far as charging electronics is concerned, please have a look to the below diagram, now it's over one year that I'm using it and it's simply fantastic.
ONE YEAR ZERO BATTERIES !!! ... that's a great success.
