I‘m pretty sure they will also offer a bundle version with battery again. But let’s wait for Wurkkos to confirm. I bought a 45W USB-C PD charger and a 100W USB-C (type C-C) cable today to be able to testing both type C-C charging and reverse charging of the HD20.
This is an excerpt from the manual, showing the UI of HD20.
Thanks for your feedback so far. I agree that HD20's weight might be a bit on the high side to some people. However, there's some potential here using it as a classic tool lamp on a belt, in one's pocket or - as I prefer to wear headlamps - around one's neck, shining in front of your feet while having both hands free.
Meanwhile, I agree with AEDe that - from a point of consistency - a single click from turbo mode should normally turn off the light instead of bringing you back to the previous standard mode. Due to the hidden strobe modes (triggered by consecutive doubleclicks) some compromises were necessary here. So, the original style was adopted, i.e. one click will return to the last used standard mode and one more click will eventually turn off the light.
I hope to keep on collaborating on the improvement of future UIs with Sofirn/Wurkkos, especially in terms of dual e-switch configurations, see my concept about Wurkkos WK30S. I hope they will soon introduce multiple firefly/moonlight modes as a separate sequence, lately introduced by Manker with their MC13 and E14 III.
I hope to receiving some updates as of October 8, 2020 (when the Golden Week ends). Wurkkos HD20 and DL30 should be launched anytime soon. Currently, it may take a while until stock is released on Amazon. The pandemic slows down everything worldwide.
Looks kind of big for a headlamp, but something like this, might be really good for a general purpose mtn bike light, especially if both lights could be run at the same time.
I hope so. My recommendation to Wurkkos was to put priority on black and army green. Blue and red will propably look great as well but create less overall demand compared to black and army green.
