In this video review and field test I challenge you to find me a better headlamp / Head torch with a better lumen output to runtime to weight ratio as I believe this HC65 UHE is class leading.. I also discuss some other features that sets this NITECORE Headlamp apart from the competition... Its a very versatile light suitable for many activities including camping, climbing, hunting and fishing, if you want a really top product with performance and durability to match... Best wishes Tom
