) ?
Thanks everyone. The feedback is much appreciated.
Battery drain has nothing to do with voltage, LED, or incandescent. Battery drain has to do with total power used. If you use a dynohub, you don't need to worry about it.
Dynamos are not voltage regulated. The lights are... at least the modern LED lights are. Some old incandescents without regulation could blow the bulb at high speed. Not an issue with modern lights.
If you buying pre-built lights and dynos, none of this is an issue. It'll just work. If you want a DIY setup, then maybe you should learn a little more about electronics first.
