Wanna see its price range before pulling the trigger.
at least $55
HC30!!! Nice! Looks exactly like the H600 without the ribbed body. Not real sure of the UI from the video but looks OK. I like how easy it appears to come out of the rubber rings.
Wow looks like Nitecore is getting creative with the ambitious ball design and the HC30 seems too much of a copy.... But for the price range it does put seem bad. Might be my first headlamp if everything checks out (although I have some doubts).
