The Fenix HM65R-T V2 is the headlamp Fenix built for people who run in the dark: a magnesium-alloy body that is roughly 30 percent lighter than the equivalent aluminum lamp, a sport headband that adjusts two ways, a dedicated 24-hour runtime mode, and both white and warm white output. It is also a very good general headlamp for anyone who values weight over raw output. Here is what it does and who it suits.

Why weight is the whole point
A headlamp that bounces is a headlamp you stop wearing. The HM65R-T V2 is built from magnesium alloy specifically to cut weight, and the SPORT headband adjusts both around and over the head so the lamp sits flat and stays put at a run. For trail running, fast hiking, or long nights of work where the lamp is on your head for hours, that is the feature that matters more than any lumen figure.
Warm white and the 24-hour mode
Two features set this lamp apart from the standard HM65R. The warm white output is easier on the eyes at close range and cuts through fog and dust better than pure white. The 24-hour mode is exactly what it sounds like: a level tuned so the lamp runs a full day on one charge, which turns it into a reliable overnight or emergency light rather than something you ration.
Battery and charging
It ships with a rechargeable 18650 and charges over USB-C in about three hours. It also accepts CR123A cells, so if you are somewhere without power you can run it on primaries. A lockout keeps it from turning on in a pack.
Durability
IP68 waterproofing and a two-meter impact rating. It is a running headlamp that will survive being dropped on rock and worn in rain.
Who should buy it
Runners, fast hikers, and anyone who wears a headlamp for long stretches and is tired of the weight. If you need maximum output and a longer beam for search or industrial work, the HM71R or HP35R are the heavier tools for that.
