Introduction
Some products fail to impress me. For a long time, I never considered a computer monitor light bar a necessary item. However, the Quntis Monitor Light Bar Focus 51 cm (20.1 inch) Black proved me wrong. It is not just a fancy addition to my workspace; it has become a highly welcome tool for my daily work routine. Let me tell you why!
In this article, I share my hands-on experience using the Quntis Monitor Light Bar Focus 51 cm (20.1 inch) Black over a period of months in my home office and hobby workspace. While a monitor light bar isn’t for everyone, I think everyone could benefit immediately from having one! Read on below to see why.
Is the Quntis Monitor Light Bar Focus 51 cm (20.1 inch) Black Worth it?
Yes. The Quntis Monitor Light Bar Focus 51 cm (20.1 inch) Black is affordable and provides way more value than you would expect upfront. For anyone who cherishes productivity, simplicity of design and function, I think the Quntis Monitor Light Bar Focus 51 cm (20.1 inch) Black is an amazing addition to anyone’s home office space. The spot light effect above your monitor with its bright and clean, glare-free output welcomes you to your workspace.
For the artist and hobbyist, the high CRI (Ra 98) provides super accurate color reproduction over your working surfaces. While I did find the restriction of the light bar to my computer monitor a bit of a hindrance, moving smaller projects in front of the screen proved to be an easy workaround.
The diffuse, yet fairly bright light provided a very comfortable working environment. Similar to the Redgrass Desk Lamp, the Quntis Light Bar also uses a step-less dimming design. By twisting the cap and outer ring of the remote, you are able to smoothly lower the brightness or adjust color temperature.

Setup and use of the light is super fast and easy. The light bar sits firmly on the top of your monitor using a counterbalanced passive clamp design. This is a common way many monitor light bars work. I tested this on two iMac models, as well as a Thunderbolt monitor. Both of these screens are of average thickness and flat in the front and back. With its adjustable clip, the Quntis Monitor Light Bar Focus 51 cm (20.1 inch) Black will also fit on curved screens and monitors!
When it comes to cost, as I mentioned the Quntis monitor light bar is one of the best-value monitor lights on the market when you consider the quality of the light, utility of features, and how welcome that remote control is when you just want to get to work. Overall, I highly recommend you check out this monitor light.

5 General Reasons to Get a Monitor Light Bar
I learned these lessons after doing some research and using a light bar myself. Here’s why you may want to consider getting a light bar for yourself!
Improves Focus
I find that illuminating my work area, beyond just ambient room lighting, helps me stay focused on the task right in front of me. I’m not tempted to look around, get up, or do other things. Using a monitor light bar compelled me to “stay in the light” to continue working. By the way, I tend to wear noise-canceling headphones as well, which helps with focus.
Promotes Productivity
Better focus and reduced eye strain lead to increased productivity, making a monitor light bar a useful tool for students, professionals, and hobbyists alike. I was able to work long hours in a dark room just by the light source provided by the light bar. While a computer monitor produces its own light, it can get uncomfortable when it’s all the light you have.
Space Savings
A light bar is a tiny package! It fits right where you already have a stand (i.e., the computer monitor) and illuminates the surfaces right in front of you. I have plenty of hobby desk lighting, but they take up some space. Even the table clamp-style lamps that I also use require swing arms that take up “air space” over my desk.
Ergonomic Side Benefits
The light bar is always in the perfect place. I don’t have to adjust placement of my lighting to fit my needs. I can avoid hunching over, squinting, or making any sort of postural adjustments to my body to ensure I can see things on my desk or computer monitor properly. It’s just more comfortable now…if only I can find a better chair (e.g., an issue to solve for another time).
Aesthetics
I love minimalism. The Quntis Light Bar is as simple and functional as you’ll get. Its thin, sleek profile stays out of your visual space. Even when you turn it on, you barely notice the lamp itself. I love that.
Of course, there may be corner cases for why you may love having a monitor light bar. Because of its focused illumination, you can work in a limited, shared space while others around you are asleep (i.e., your roommate, a spouse, kids). Because the remote control allows you to control the light without touching the light bar, you don’t have to worry about re-adjusting the placement of the lamp every time you turn it on or off.
Simplicity in design makes any product versatile. This is the case with the Quntis Monitor Light Bar Focus 51 cm (20.1 inch) Black, too. You can be creative with how you use it.
Unboxing and Impressions
Alright, let me dig a bit deeper for you. Upon arrival the light bar came in a neatly packed box. As you would expect, the exterior gave me plenty of information about what I would find inside.
The Styrofoam white tray contained the seven pieces of the product, including the LED light bar, a monitor clip, a remote control, a USB-C cable, a hex key, 2 AAA batteries and the user manual.
The instruction manual was clear and helped me install the light bar. The light bar itself is a thin 51 cm (20.1 inch) long LED panel that provides a broad illumination across most wide aspect ratio computer monitors.
The light bar fit perfectly across my iMac. I didn’t have to use any of the adjustable adapters to make it fit and it looked great.
A Pleasant Surprise…Seriously
I never thought I’d recommend a monitor light bar as a worthy investment. But, after having used one for a few months, I’ve come to find several compelling reasons why I’d buy one myself.
Do you want “things” that help you stay focused? I always look for ways to stay focused on all the multitude of tasks I have to work on. I’m an academic professor who works quite a lot at home. I write papers, I perform online research, and I take breaks with a miniature painting hobby in-between.
The Remote Control is Wonderful
The Quntis Monitor Light Bar Focus 51 cm (20.1 inch) Black reviewed here includes a remote control. It is essentially a round knob about the diameter of a soda can. There’s a slight blue accent under the top button that gives this unassuming look some color pop. Suffice it to say, it looks great on my desk like it belongs there.
