CYANSKY HS7R headlamp

REVIEW – In my job I often work in dark spaces, under counters, in equipment racks, in ceilings, all situations that require me to use a flashlight, preferably hands-free. I’ve held flashlights in my teeth before but since they’re almost always made of metal that’s not very comfortable. I can use a work light, sitting on a table or hanging from something, but that’s not always pointing where I need it. For situations like these I prefer to use a headlamp. When the opportunity came up to review the CYANSKY HS7R 2,800 Lumen Headlamp I was excited to test it out.

What is it?

The CYANSKY HS7R is a bright headlamp with a spotlight and floodlight mode. The light includes a band that goes around and over the head or a hard hat to support the light for hands-free use, but it’s also removable for handheld use, and also includes a magnetic tail cap to allow it to be hung in a variety of positions. With the included rechargeable battery this light should last for several long days of working in dark spaces.

Design and features

This flashlight shares the typical barrel style form factor, except that the LEDs are on a small section that is 90º to the rest of the body rather than at the end of the light. This form factor allows it to be used as a headlamp or to be handheld and with the magnetic tail cap it can be easily attached to a metal surface. The body of the light is made from an aluminum alloy which feels like it can withstand quite a bit of shock. The body features an anti-slip design pattern and the tail cap has several flat spots to help prevent the light from rolling off a table.

The light features two sets of LEDs, one a spotlight and one a floodlight. The spotlight has a 20º lens and can light up to 186 meters; the floodlight has a 90º lens and can light up to 91 meters. There are two different color temperatures as well: the spotlight is a cooler color and the floodlight is warmer; not an extreme difference but noticeable. The cooler light makes the spotlight mode feel even brighter.

There are two on/off switches on the CYANSKY HS7R headlamp, one at the top, which is a silicone-covered button. The other switch is a smaller metallic button, on the right side of the light if you’re looking at the LEDs.

When in the headband bracket the light can tilt 90º +/-, allowing for a 180º swing to reach whatever you’re trying to illuminate in front of you.

The spotlight has four brightness levels, up to 2,800 lumens, and the floodlight has four brightness levels, up to 2,000 lumens. Each mode includes a memory function, which returns the light to the last used brightness level when turned on each time, except turbo mode. Both modes can run in turbo level for up to 1 minute, after which the lights return to the high level for temperature protection. When the battery level runs down to 3V the light automatically switches to low mode and shuts off when the battery gets to 2.7V. 

This light also features a light sensor, which automatically lowers the brightness when it’s too close to an object to prevent burning skin or melting through a pocket or pouch. This sensor can be defeated by double-pressing the top switch.

The CYANSKY HS7R headlamp is capable of fast charging, only taking 2 hours to charge at 5V/2A, which is about typical for a 5,000 mAh battery. The battery is removable and is the 21700 size.

Inside the silicone button at the top there is a battery level display, which lights up when the flashlight is turned on or when either button is quickly pressed while the light is off. There are four levels of battery level indication:

  • Solid Green: 76% – 100%
  • Flashing Green: 50% – 75%
  • Solid Red: 26% – 50%
  • Flashing red: <25%

The CYANSKY HS7R headlamp also features a lockout mode which can be enabled by pressing either button for 3 seconds. After flashing a couple of times the light turns off and is locked. While in lockout mode, pressing either button flashes that mode’s LEDs twice. To unlock the light, press either button again for 3 seconds.

The included headband fits around the head comfortably and can be expanded to fit around a hard hat for situations that require it.

Installation and setup

The flashlight came out of the box partially charged. Before first use, there is a small plastic insert that has to be removed. It’s always recommended to fully charge a new device before using it. Once that is done and the light is clipped into the headband, it’s ready to be used.

To turn on the flashlight, press the top button for .5 seconds for spotlight mode. Pressing the button again cycles through low, medium, high, and turbo brightness levels. To turn on the floodlight mode, press the small metal button for .5 seconds; pressing it again will cycle through low, medium, high, and turbo modes for the floodlight as well. To turn off from either mode, press that mode’s button for .5 seconds.

In use

The CYANSKY HS7R is a really bright headlamp. Both the spotlight and floodlight modes reach a pretty high brightness level. I can’t imagine a work situation where this headlamp won’t be bright enough. I know there are more extreme jobs out there than mine so someone can probably come up with a situation where this light isn’t enough, but for the average Joe, this light is going to be plenty bright.

The aluminum construction is solid and feels like it’s built to last. Considering that it features IP68 water & dust resistance, this light will last a long time.

The magnetic tail cap isn’t the strongest magnet I’ve ever used but it attaches and stays put to any standard ferromagnetic metal, flat surface, and since the light only weighs about half a pound I think it’s plenty strong to stay put.

The proximity sensor is very effective and instantaneous. I plan to keep this feature on all the time because after just a few seconds of turbo mode shining right at my hand, it started to feel uncomfortably hot. The body of the light where the LEDs are housed also gets pretty hot after a little while, too hot to hold very long for sure. There is plenty of surface area to still hold on to, but be careful of the head as it will start to feel uncomfortable after just a few seconds in turbo mode. When strapped onto the head this shouldn’t be an issue because the headband and steel bracket keep the light far enough away from the skin that it shouldn’t be a problem.

The CYANSKY HS7R headlamp isn’t heavy per se, but it is the largest headlamp I’ve ever used. When it’s strapped to your head you won’t forget it’s there. It’s not painful really but you’ll notice the weight a little bit. I suppose if you use it with a hard hat you won’t even notice the added weight.

There is no strobe mode available with this flashlight. I assume that’s because it’s meant as a headlamp and not a primary flashlight for most people, so presumably, you’ll have another one that can strobe. A 2,800 lumen strobe light would be pretty effective, though. I’ve never actually used a strobe mode with any of my flashlights, but I always like knowing it’s there just in case.

One thing I’m hoping for is that the silicone cover over the top button will last. I recently had to retire a much cheaper flashlight that I bought less than a year ago because the rubber cover over the button broke apart under average use. I didn’t pay much for the light but it was still unfortunate. CYANSKY says their button withstood 100,000 presses in testing so I don’t expect this to be a problem.

What I like

  • Flexibility
  • Brightness
  • Spotlight and floodlight options
  • Proximity sensor
  • IP68 rating

What I’d change

  • It feels a little too heavy on the head after a while

Final thoughts

Since the CYANSKY HS7R headlamp doesn’t include a holster I won’t be able to use it as an everyday carry light, but I do plan to keep it either in my backpack or at work so I always have a bright light available when I’m working in dark spaces. With the options of being head-mounted, handheld, or magnetically attached, I’m sure this light will come in handy anywhere I need to see more clearly.

    1. I didn’t have any problems with this one. It’s pretty tight so getting the light in or out takes some force. Perhaps they’ve made it stronger than the one you have?

      1. Light Sensor, not a Proximity Sensor. If it was a Proximity Sensor the detection range would stay the same for white and black surfaces, and regardless of what mode you’re on, high has a short range than turbo.

        1. Thank you for your comment. I was not aware of the difference and assumed it was changing modes because it came in close proximity to my hand or other objects. I stand corrected.
