While using the light I’ve made a few observations:
- In some instances, as the battery gets low the light flickers a bit, likely due to it trying to maintain the highest output possible.
- For a total battery drain, I got 5 hours from Turbo to off
- The battery took about 1 hr 20 min to charge using the built-in charger
Look & Feel
This is my first 1xCR123A style headlamp and I was a bit shocked how small it was compared to other 1×18650 sized headlamps. Since the light is so small there isn’t much to see except the head of the light with the switch and a bit of the tail. The look of the head is a little square shaped which I think helps add a bit of ruggedness which helps balance the short overall size. The squareness also allows for more finger purchase when tilting the light.
Compared to the predecessor HM50 , many things have changed but, I think that the most innovative of the look or feel is the addition of USB charging and the new sweat-stopper ring on the inside of the headband. Other notable changes are changing the headmout to rubber instead of metal, the ‘bezel’ of the light now has a circular look, the headband has the new navy and orange pattern, and the tail cap has a new knurling style.
About the light itself, I like the large switch and the tail cap has several extra threads so it’s really easy to screw on the cap.
I also think that the USB cover is done really well as you can pull the whole thing off if needed, without damaging it.
The head mount could be improved a bit. The part that holds the light feels too tight which affects both ease in taking off the light and putting it back in plus the added force needed to tilt the light. Instruction manual does say you need to remove the tail cap before taking the light out of the mount but I would never do that outdoors or at night for fear of dropping something in the dirt or losing a component altogether. This headmount style is probably a step back from the ease of the predecessor HM50. Also as a note, the mount is not symmetrical so you need to pay a little attention to that. Also the mount’s brackets for the head band are thicker which is nice for durability but is felt a bit more on the forehead. Since they provided an extra mount maybe they could have lightened up the specs a bit on the rubber gauge.
The headband is pretty neat. I like the new sweat stopper and I feel it works very well. I was nervous at first of it gripping too much and pulling out hair but it is actually very soft. Overall I like how it helps prevent headband movement while in use.
In combination of the domed CREE XM-L2 led, the light uses a smooth reflector. Using a printed protractor, the total spill angle is about total 80 degree angle with a slight spot with 20 degree total angle.
The beam color is pretty neutral in the center but the spill is fairly cool with light purple tint.
The UI is fairly straight forward with no hidden modes or shortcuts to turbo or low. The light is controlled by a single electronic switch. To turn on and off the light press and hold the switch. When the light is on, a quick press on the switch cycles the modes.
The modes cycle beginning in LOW -> MED -> HIGH -> TURBO. The light has mode memory.
When off, a single tap of the switch initiates a battery level check:
- Green constant on: more than 80%
- Green flashes: 50% – 80%
- Blue constant on: 20% – 50%
- Blue flashes: less than 20%
The light can be locked out, to prevent parasitic drain or accidental activation, by unscrewing the tail cap a quarter turn or more.
Overall, I like the UI but wish it was quicker to turn on the light. It is also a bit of a surprise that there are no special modes like a constant flash mode or SOS, which could have been accessed from off using a quick double press perhaps.
By default, the HM50R does come with a single 16340 with 700mAh capacity, product number ARB-L16-700. The battery takes about XX hours to charge in the light which charges around 1 amp. During charging the indicator light will be constant blue; when full it will turn constant green. Also while plugged in, the light can operate on HIGH pretty much continuously.
