Nitecore NU21 thoughts ultra lightweight headlamp

Nitecore NU21 lightweight headlamp for outdoors and trail running. Having used and enjoyed the NU33 for as simple pick up and go light I was happy to look at this smaller brother. Stripped right back with a quick lace style band and low weight. So far im having fun testing it. Is it enough to actually trail run with? im still testing that. full review up when all testing is complete.
