If you spend hours every day staring at your screen, a monitor light bar can help reduce eye strain, prevent headaches, and illuminate your desk. Most monitor light bars let you adjust brightness and color temperature to your liking, and some even feature auto-dimming.
What to Look for in a Monitor Light Bar
There are multiple monitor light bars that offer the same features, so finding the best one for you can be tricky. Because a monitor light bar is a small gadget, the list of what to look for is fairly short.
Some light bars have only one brightness level or one color temperature setting—you’ll want to avoid these. There are so many other options out there that allow you to customize brightness and color temperature with three to fifteen unique settings.
A monitor light bar with a wireless remote or an auto-dimming feature can be helpful so you don’t need to reach up to manually adjust your settings throughout the day. These features can be especially helpful if you play games, but anyone using their monitor for long hours can benefit from a wireless remote or auto-dimming.
Measuring is key when selecting a monitor light bar. Make sure the monitor light bar you choose is the proper size for your monitor, or you run the risk of screen glare. If you have a curved monitor, find a light bar that mentions compatibility with curved monitors, or a light bar that’s specifically made for curved monitors.
Mounting a light bar to your monitor should be easy, but not all monitors are equal. Even some of the best monitor light bars prove difficult to mount on some monitors. Check reviews for images or anecdotes about mounting the light bar to monitors that resemble yours, and try to find out how long the connecting cable is to make sure there’s plenty of space between a USB port and the top of your monitor.

Best Monitor Light Bar Overall: BenQ ScreenBar
|
Pros |
Cons |
|---|---|
|
✓ 15 adjustable brightness levels |
✗ Mixed results on compatibility with curved monitors |
|
✓ 8 adjustable temperature levels |
✗ Pricey compared to similar light bars |
|
✓ Auto-dimming feature |
|
|
✓ Durable, premium build quality |
For most people, the BenQ ScreenBar is the best monitor light bar you can buy. It’s a bit pricier than other options, but in exchange for that premium, you get a light bar that’s made to last longer and has a few extra features.
There are 15 adjustable brightness levels and eight different color temperatures between 2700K (warm white) and 8500K (cool white). You can adjust the brightness or color temperature manually using controls on the light bar, or you can use the built-in auto-dimming feature to automatically adjust the levels throughout the day as outside light fluctuates.
The ScreenBar’s auto-dimming feature uses a built-in ambient light sensor to detect surrounding brightness and adjust it to 500 lux, the American National Standard recommendation for office lighting. In the light bar’s center, the max brightness reaches 900 lux. Whatever your brightness is set at, BenQ’s patented asymmetrical optical design creates zero screen glare.
BenQ’s ScreenBar can be powered by any USB outlet with an output of 5V/1A or more. It clamps onto your monitor easily, and no tools are required. On the BenQ website, you can find monitor compatibility requirements for the ScreenBar. It should work with most flat or curved monitors with a thickness between 0.4 and 1.2 inches. However, some Amazon users have reported the ScreenBar is not working well with their curved monitor.

The Quntis Light Bar is a solid budget-friendly alternative to the BenQ ScreenBar. It packs similar features with some nice upgrades over its predecessor. It has an asymmetrical optical design that prevents screen glare, an auto-dimming function, a smart remote controller, and is easy to install.
Inside, you’ll find 84 LEDs and a built-in ambient light sensor that automatically adjusts brightness based on your surroundings. The sensor keeps the brightness at around 700 lux, which meets U.S. workplace lighting standards.
You can also manually adjust the brightness up to 840 lux in four levels (each increasing by 25%) and choose from four color temperatures between 3000K (warm) and 6500K (cold). No matter how you set it, the Quntis Light Bar helps reduce blue light and eye strain, keeping you comfortable all day.
It’s super easy to power; just plug it into any USB 5V/1A port, whether that’s your monitor, computer, or even a power bank. Unlike the previous model, which only fit monitors between 0.3 and 1.4 inches thick, this version works with all bezel sizes and curved screens.
Thanks to its improved sliding weighted clip, it securely fits ultra-thin bezels and curved monitors. You can adjust the distance between the clip and screen for a stable setup, no matter your monitor’s thickness.

The HIOUME Light Bar is perfect for anyone looking for a light bar that fits on a smaller, thinner monitor. This light bar measures 15.75 inches, a few inches shorter than most other options available.
With its asymmetrical optical design, it won’t create screen glare. Then, there are three color temperature options to switch between, from warm light (2800K) to cool light (6500K) to somewhere in the middle (4000K). You can also adjust the brightness in 10% increments, from 10% to 100%.
This light bar contains 84 LEDs (42 Cool White LEDs and 42 Warm Color LEDs), and HIOUME estimates the LED lifetime to be over 100,000 hours. In the center of the light bar, it can reach 500 lux max brightness.
Because HIOUME’s monitor light bar uses a clamp design, you won’t need any tools to install it. However, you will need to measure your monitor to make sure it’s compatible. This monitor bar will work with any flat monitor with a thickness between 0.4 and 1.2 inches at the top; it’s not suitable for curved monitors.
To use the light bar, plug it into a 5V USB port on your computer, monitor, USB charger, or power bank. Once it’s plugged in, you can adjust the brightness and color temperature using manual controls on top of the light bar.

The Xiaomi Mi Light Bar is a great option for anyone who plays games because it comes with a remote control and doesn’t have an auto-dimming feature, which can be annoying while gaming. The remote is wireless via a 2.4GHz connection, and it can be pressed, rotated, or both to control your brightness and color temperature preferences.
There are multiple brightness and color temperature settings to play around with, and the response from the wireless remote control is almost instant. Like other light bars, this one from Xiaomi produces no screen glare or reflection because of its asymmetric design. Not every monitor is built the same, so the light bar can be adjusted up to 25 degrees to prevent glare on most monitors.
Xiaomi’s Light Bar gets its power from any USB port, and you can start using it as soon as it’s plugged in. You can quickly attach this light bar to your monitor via clamp installation and adjust the angle easily with its magnetic base as long as the top of your monitor is between 0.4 and 1.25 inches thick.
You can still install this light bar on monitors less than 0.4 inches thick, but you won’t be able to adjust the angle without supporting the light bar. Xiaomi even states this light bar is suitable for curved screens with or without a bezel that falls into the thickness requirements. The 40-degree adjustable axis lets you put the light bar in just the right place to prevent screen glare.

Best Monitor Light Bar with Webcam Mount: BenQ ScreenBar Halo

Pros |
Cons |
|---|---|
|
✓ Adjustable color temperature and brightness |
✗ Super pricey investment |
|
✓ 3 eye-care modes to choose from |
✗ No controls on the light bar |
|
✓ Convenient wireless remote included |
|
|

You can put your webcam beside a monitor light bar or try to mount it on top with tape or great balance, but if you want a light bar with a dedicated place for your webcam, check out the BenQ ScreenBar Halo and its Webcam Accessory. There’s a special spot dedicated for the Webcam Accessory on top of the ScreenBar Halo, and it’ll work with many other webcams (but not the BenQ IdeaCam).
The ScreenBar Halo is a great pick for anyone wanting to use a light bar and a webcam, but quite a few extra features make it a fantastic premium pick as well. It shares some features with the original ScreenBar, like auto-dimming to 500 lux, an asymmetrical optical design to prevent glare, easy installation, and multiple adjustments for brightness and color temperature. Unique to the ScreenBar Halo, you’ll find an integrated backlight and a handy wireless controller.
You can control brightness and color temperature levels for the backlight and the front light. Then, you can easily swap between three different modes that utilize either just the front light, just the backlight, or both lights. Using just the front light might be better for working during the day, and using just the backlight can be more immersive for playing games at night.
You can use the included smart wireless controller to control the brightness and color temperature settings. Between the three eye care modes, there are over 100 different brightness and color temperature combinations to experiment with.
The ScreenBar Halo is easy to install via an included USB cable and BenQ’s patented clip design. It’s also compatible with more monitors than the original ScreenBar. Flat monitors with a thickness between 0.3 and 2.4 inches and curved monitors over 1000R with a thickness between 0.63 and 1.5 inches are compatible with the ScreenBar Halo. Your monitor’s bezel width should be greater than or equal to 0.25 inches to work with this light bar.

FAQ
Do monitor light bars help with eye strain?
Yes! It may seem counterintuitive, but by providing extra light via a light bar, your eyes won’t need to constantly adjust to your screen’s brightness as the surrounding light changes throughout the day.
Should I use a monitor light bar or a monitor backlight?
Both light bars and backlights (or bias lighting) help reduce eye strain by providing consistent and ample light around your screen, but light bars can help illuminate your desk as well as your screen.
What is blue light?
Blue light is simply light with a blue hue that produces a higher amount of energy than other colors, and believe it or not, blue light is not as dangerous as people make it out to be.
