Fenix HM50R v2

4.5

3 sources$59.95as of Aug 1

The Fenix HM50R V2 weighs 2.75 ounces, puts out 700 lumens, and throws a beam 377 feet. Reviewers noted the IP68 waterproof rating and the USB-C charging cable in the box, though some disliked that activation takes a long press rather than a single click. The clip is stiff, which keeps it stable but makes reattachment hard for children. It handles technical outdoor tasks well, but the feature set is thin and there's no flood function.

Strengths

— Lightweight at 2.75 ounces, suitable for backpacking, running, and climbing
— Bright output of 700 lumens with a beam distance of 377 feet
— Durable aluminum construction with IP68 waterproof rating

Watch-outs

— Limited features with only 4 modes and no flood function
— Activation requires long press instead of single click
— Stiff clip makes it difficult for children to reattach the headlamp

How they stack up

Fenix HM50R v2

The Fenix HM50R v2 surpasses the Nitecore NU27 600 in brightness with 700 lumens versus 600, and offers superior durability with an IP68 rating. However, it's less user-friendly than the Petzl SWIFT LT, which has a simple one-button operation, and lacks the adjustable color temperature of the Nitecore NU27 600.

Nitecore NU25 400 UL

Against the Silva Trail Runner Free H it is cheaper and lighter, but it gives up the Silva's hybrid battery system and its simpler brightness switching. Among ultralight rechargeable lamps its strength is feature count per gram rather than raw output.
