REVIEW – There are times when you need to use a light, but also need to use both hands. Depending on the situation, this can be easy (you’re at a table with a desk lamp) or difficult (you’re pitching your tent at a campsite that was two hours further down the trail than you expected, so it’s way past sunset). If you’re wanting to move, a headlamp is a nice thing to have. I’ve been testing the Cyansky HS5R headlamp that not only has the usual LED light multi-level brightness features, but adds a red mode to preserve your night vision. Let’s take a look.

What is it?

The Cyansky HS5R headlamp is a rechargeable LED light with 90º angled head, with headlamp strap and pocket clip.

Design and features

The Cyansky HS5R headlamp is a cylinder that is 3.625″ long and .75″ in diameter. The reflector (also .75″ in diameter) is at a right angle to the body of the light, and the activating switch is mounted on the end of the main cylinder near the reflector, surrounded by a blue anodized metal ring. A long press activates the switch. While the light is activated, a quick press will cycle between a regular beam, a red safety light, and a blinking red safety light. Turning the light off is done by holding down the button for a long press. The light will come back on in whatever state it is in when it is shut off. A long press on the button while it is in regular mode, will switch to a bit higher white light and back. (It all seemed kinda hit-or-miss, it seems to me. I could find no logic in the sequences but could easily get to the level I wanted by trial-and-error.)

The Cyansky HS5R recharges with an (included) USB-C cable from whatever power adapter you use to attach it to the weather-sealed port near the switch. There is an indicator light under the switch that glows red as it is charging and then green once the battery is full.

The tailpiece is a flat magnetic base, so you can attach it to network racks, filing cabinets, or car hoods while doing two-handed work. The angled head makes it very flexible for focusing on the task at hand. The clip is also quite versatile since you can attach it to a strap, belt, or shirt from either side.

The tailpiece is flat and magnetic.


The Cyansky HS5R headlamp is attached to a 1.5″ width headstrap with a metal wire bail attached to a 3″ X 1.675″ base. When strapped to your head, the light can be rotated to focus on whatever task you need to work on. There’s a foam pad that you can place under the strap to cushion your head from the metal plate if desired.

Here’s a quick video comparing the levels and the red light/flashing light settings. For the life of me, I can’t figure out how to go easily from one to the other. I just keep clicking until one that I think I can use comes along.

Ostensibly, you can unclip it and use it as a stand-alone light. It took me several long periods of trying with various tools to unclip the light. After I finally managed to extricate it from its metal prison, I could never discover how to re-clip it to the headstrap. (There was nothing in the paperwork or on the website about unclipping the light from the headstrap.) It looks like it would be an easy task, but the wire is very stiff, and when I tried to squeeze it with pliers to get it undone, it bent in one place. Once it was freed, I attached the included two-way spring steel clip, however, and it is a nice body-mounted light. The right-angle lens allows it to hug your body better and not flop around while you move. The Fresnel lens gives the beam a full, even center with a nicely faded ring around it.

What I like

  • Red light saves night vision
  • Right-angle light allows for better focus while keeping the body of light next to the head or body

What I’d change

  • Confusing pattern for changing between lighting modes
  • Unclipping the light from the headstrap is nearly impossible
  • Reattaching the light to the headstrap is impossible

Final thoughts

The Cyansky HS5R headlamp is a very confusing unit. It’s a great little flashlight, with several white levels, as well as a red safety mode and a flashing red mode, but the sequence of presses, long presses, and even longer presses needed to move between modes never made sense to me in my testing. Also, the bracket that holds the light to the very nice elastic headstrap was stiff and difficult to work with. If there had been no spring clip in the bag, I would have just assumed it was not meant to detach and used it as a headlamp only. I’m actually sad I can’t reattach it to the strap and use it while grilling or working in dark places. But it’s a nice enough light unattached, with the clip and the magnetic base.

  2. Will it chare with a true USB-c cable? I.E. a cable with USB-C connectors on both ends. I ask because I’ve encountered a goodly number of products that don’t. The will only charge with the USB-A to USB-C cable that came with it.

    1. I just tested this with my Apple 20-watt charger and the cable that came with my iPad Pro. It will not charge with the higher watt charger. Plugged in the USB-A<=>USB-C cable plugged into a 5-watt charger and it charged right up. (Plugged in the same outlet!) I will test this closely in future reviews. Thanks for asking about this issue!

      1. Thanks because it’s very clear that a USB-C port is not actually proof that a device can charge with a true USB-C cable. I have all but eliminated USB-A chargers from my life. My wall chargers only have USB-C ports, my car charger only has USB-C ports. The goal here is that the same USB-C to USB-C cable will charge everything, from headphones, to bluetooth speakers, to my phone, to even my laptop (with a 100 watt capable wall charger and cable). If it only works with a proprietary USB-A to USB-C cable I don’t want it. There must be some reason manufactures are doing this because it’s fairly common.

        1. I’m not sure of what the wiring differences are, but I’ve seen it anecdotally in the past. When you asked, I realized this isn’t a regular part of my testing. It will be going forward, and I will probably go back and test a few other devices for the same behavior. I don’t think the cable is proprietary, just limited in how much juice it’ll allow through. The USB-A<=>USB-C cable I tested that worked was not the one that came with this light, but just one I had put onto a breakout box on my desk that has every known wiring protocol and plug type attached. ;-D
