I use a Son28 with a Sinewave Beacon and the biggest advantage for night riding is the ability to supplement the power with a small lipstick sized charger. The steady output is appreciated for technical, slow uphills, or even hike-a-bike sections. One charge (3300 mah capacity battery, I think) lasts all night for me under normal conditions.
Oh.. it's also a USB charger as well ;0 ) On Monday, April 29, 2019 at 6:33:45 PM UTC-4, Collin A wrote: > > Given some discussion in another thread about dynamo lighting use on > unpaved surfaces, I figured it would be worth bringing this up as a > separate thread. > > Personally, I have a kasai Dynacoil hub (evolution of a SP hub, I believe) > laced to an Alex Dm24 rim and wired with a K-lite bikepacker light (gravel > version) https://www.kliteusa.net/product-page/klite.
