12.4w Dynamo powered, LED bike lights
Just doing some testing with the new Shimano dynamo hub, & 4 series 3w LS...using a load matching circuit...WOW, Max output 12.4w!!
so power @ low speed is ok for me...used a flater curve for the voltage db circuit, more down the bottom end & less drop to transition...
Then a more peaky curve for the full wave so I could hit the max... not too worried about the other side of that curve as not much riding is above 50km/hr...
I am not kidding, its like a HID out on the trail!!! I am super happy!!!
Now if I can just ride always @ 40km/hr....
if anyone wants pic's / specs, let me know
