Great to use this for daily vehicle inspections and a cheap right angle torch for clipping onto yourself (leaving your hands free). I tested Fenix headlamps many years ago and, at the time, their quality was not up to the standards of their flashlight line. But what’s more interesting is that it started to get charged with three indicators on and one flashes constantly till it get fully charged.

For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor. Maximum beam distance 163 meters (spotlight mode) or 55 meters (floodlight mode), waterproof to IP68 and resistant to impacts up to 2 meters. It's worth studying the lumens versus duration graphs to find your best setting, especially if you will be using it for long periods between charges. The primary power option is a single rechargeable 18650 battery (included); as a secondary option, you can also power the Fenix HM65R ShadowMaster with two CR123A batteries.Fenix HM65R-T is powered by an included 3400mAh 18650 battery which is charged via the USB-C charging port on the rear of the headlamp (charging cable included). If a student had a camera question that I needed to turn on a light for, I was able just to turn on the lowest light setting without having to go through all the settings.

There is also a low voltage warning function that will flash to warn you if the voltage is too low to sustain the current output and notify the user that the battery needs charging. The primary power option is a single rechargeable 18650 battery (included); as a secondary option, you can also power the HM65R with two CR123A batteries. The spotlight on this model has been more than adequately bright on the high level, and it still has a turbo mode brighter than that. In the past, the 18650’s were for the enthusiast, these days, they’re easy to get hold of, and they’re affordable.After reading reviews and watching some YouTube videos, I decided to make my purchase of this light. Unfortunately, the PWM on this light is so bad that it doesn’t even work with my normal scale, which is 50 microseconds (50us). The charging socket is neatly sited with a waterproof cover so the submersion performance seems realistic. Take this thing out hill walking at night and you can illuminate the entire hillside, even the red light on full is incredibly bright and I've never seen another red light this powerful.
