This article reviews the top monitor light bars and screen-mounted lighting solutions that reduce eye strain and eliminate glare for remote workers and gamers.
If you spend hours every day staring at your screen, whether for work, gaming, or creative projects, proper lighting is essential for eye health and productivity. Monitor light bars have emerged as one of the most effective solutions for workspace illumination, offering glare-free lighting that saves desk space while reducing eye strain.
After extensive testing and analysis of user reviews from Amazon, Target, and Walmart, we've compiled this comprehensive guide to the best monitor light bars available in 2025. These innovative devices attach to the top of your monitor and provide targeted illumination without causing screen reflections—a common problem with traditional desk lamps.
Monitor light bars address several critical workspace challenges. They provide uniform lighting on your desk surface, reducing eye strain by up to 60% according to studies by the American Optometric Association. By minimizing the contrast between your screen and surrounding area, these devices help prevent computer vision syndrome, which affects millions of office workers and gamers.
Unlike traditional desk lamps that take up valuable surface area, monitor light bars attach directly to your monitor, saving up to 30% of desk space according to the National Institute for Occupational Safety and Health. They cast light downward in an asymmetrical pattern, illuminating your keyboard and documents without reflecting off your screen.
BenQ ScreenBar Halo 2 on Amazon
The BenQ ScreenBar Halo 2 represents the gold standard in monitor lighting. During our testing, this premium light bar stood out for its exceptional build quality and innovative features that justify its higher price point.
Key Features:
- Wireless dial controller for effortless adjustment without reaching up to your monitor
- Auto-dimming to 500 lux using ambient light sensor

In our testing, the BenQ Halo created the most uniform light distribution we've seen, with brightness reaching up to 1000 lux at the center. The wireless controller is incredibly smooth to operate, allowing you to adjust brightness and color temperature with intuitive dial movements. The backlight feature adds bias lighting that creates a cozy atmosphere while reducing the harsh contrast between your bright screen and dark surroundings.
What Buyers Say: Amazon reviewers consistently praise the Halo's "game-changing" impact on their workspace. Users report significant reductions in evening headaches and eye fatigue. One reviewer noted, "The ScreenBar Halo eliminates glare, reduces eye strain, and lights up my desk for comfortable, efficient work in the dark." However, some users with curved monitors mention needing additional adjustments or accessories to ensure stable mounting.
Released in 2024, the BenQ ScreenBar Pro is designed specifically to address compatibility issues with various monitor types, particularly curved and ultrawide displays. With adjustable clamps that fit monitors between 0.17 and 2.56 inches thick and support for curvatures between 1000R and 1800R, this model solves the mounting challenges that plagued earlier versions.
Standout Features:
- Motion sensor for automatic on/off functionality

- Eight capacitive touch controls on top of the bar
- Favorite setting memory function
- Compact design without backlight for sleeker profile
- 18.5 inches of LED lights using third-generation asymmetrical lighting
- USB-C powered (5V 1.7A minimum)
During testing, we found the ScreenBar Pro's motion sensor to be remarkably convenient—the light automatically turns on when you sit down at your desk. The illumination covers a 2.8 x 1.6 ft workspace effectively. The aluminum and zinc alloy construction feels premium and durable.
User Feedback: Reviewers appreciate the Pro's improved compatibility and brightness. Many note that it's the "just right" option between the basic ScreenBar and the more expensive Halo. The motion sensor receives particular praise for its convenience, though some users prefer manual control and disable this feature.
Xiaomi Mi Computer Monitor Light Bar on Amazon
At roughly half the price of the BenQ ScreenBar, the Xiaomi Mi Computer Monitor Light Bar delivers exceptional value. This light bar has become a favorite among budget-conscious users who don't want to compromise on essential features.
Features:
- Wireless 2.4GHz remote control puck

We found the Xiaomi light bar's wireless remote to be one of its most compelling features. The minimalist puck design sits unobtrusively on your desk, and the dial mechanism provides smooth, infinite adjustment of both brightness and color temperature. The magnetic attachment system allows easy removal of the light bar for cleaning.
Customer Reviews: Amazon buyers frequently mention that the Xiaomi light bar rivals the BenQ in build quality despite costing significantly less. Many users report the device lasting over two years with daily use. One reviewer stated, "At half the price of the BenQ screen bar, we would happily buy this one every time." The only common complaint is that the angle adjustment range could be greater.
Quntis Monitor Light Bar Pro+ on Amazon
The Quntis Monitor Light Bar Pro+ consistently ranks as Amazon's #1 Best Seller in USB Reading Lights, with a 4.6 out of 5-star rating from nearly 8,000 reviews. At around $40-60, it offers impressive features for the price.

User Experiences: Amazon reviewers praise the Quntis Pro+ for its excellent value proposition. Many note it provides "half the price of brands like BenQ" while delivering comparable performance. Users particularly appreciate the auto-dimming feature and the convenience of the wireless remote. Some reviewers mention the light bar has "improved my work-from-home setup" significantly. A few users note that while the asymmetrical lighting helps reduce glare, it doesn't completely eliminate it like higher-end models.
For gamers and content creators who want to add ambiance to their setup, the Quntis RGB Pro+ combines functional front lighting with customizable RGB backlighting.
Features:
- Dual lighting: front task light plus 40 RGB LEDs on back

The color accuracy with 95+ CRI makes it suitable for photo editing and color-sensitive work.
What Gamers Say: Users love the customization options and the ability to sync lighting with music. One reviewer noted that it "adds a splash of color to your workstation" while providing practical desk lighting. The fact that it doesn't require a smartphone app is seen as a plus by many who appreciate the simplicity of physical controls.
Before purchasing, measure your monitor's top bezel thickness. Most light bars fit monitors between 0.3 and 1.2 inches thick, but specifications vary. If you have a curved monitor, look for models specifically designed to accommodate curvature, typically supporting 1000R to 1800R curves. Ultra-thin monitors (less than 10mm) may require additional support or may not provide a stable mount for heavier light bars.
Light bars offer three main control methods. Touch controls on the bar itself are the most affordable but require reaching up to adjust settings. Wired controllers sit on your desk for convenient access but add cable clutter. Wireless remotes provide the best user experience—you can adjust lighting without reaching or dealing with extra cables, though they require batteries.
Look for a color temperature range of 2700K (warm) to 6500K (cool) with stepless adjustment for maximum flexibility. The Color Rendering Index (CRI) matters for color-accurate work—aim for Ra95 or higher if you do photo editing, video production, or design work. Auto-dimming features use ambient light sensors to maintain optimal brightness throughout the day, typically targeting 500 lux as recommended by office lighting standards.
This is the most critical feature for preventing screen glare. Quality monitor light bars use asymmetrical optical designs that direct light downward onto your desk without reflecting off your screen. Premium models like BenQ products create a distinct line where light stops, completely eliminating screen reflections. Budget options may allow some light bleed onto the display.
Most monitor light bars are USB-powered, typically requiring 5V/1A or 5V/1.5A. This allows powering from your monitor's USB port, computer, or a USB wall adapter. Consider whether you want the light to automatically turn off when your computer sleeps or prefer it to remain on when powered by a dedicated adapter.
Installing a monitor light bar is typically straightforward. Most use a weighted counterbalance clamp that hooks over the top of your monitor—no tools required. Place the clamp on the center top of your monitor, ensuring the weight hangs down the back for stability. The bottom of the mount should rest firmly against the back of your display.
For optimal lighting, adjust the angle so light falls on your keyboard and desk surface without entering your field of vision. Most bars offer 20-35 degrees of tilt adjustment. If you use a webcam, check that the light bar doesn't obstruct it—some manufacturers offer webcam accessories to mount alongside the light bar.
Connect the USB power cable to your preferred power source. Cable length typically ranges from 5 to 6 feet, sufficient for most setups. If the cable feels short, USB extension cables work fine with these low-power devices.
Most monitor light bars are not designed for laptops because they require vertical mounting with a counterweight system. The weight could damage thin laptop screens. However, some manufacturers offer laptop-specific models like the BenQ LaptopBar designed for portable use.
No. Quality monitor light bars use padded clamps or weighted mounting systems that don't apply pressure directly to the screen. They rest on the bezel and use gravity to stay in place rather than clamping force.
For office work, aim for 500 lux at your desk surface, which matches the American National Standard recommendation. Many quality light bars offer 500-1000 lux output. Adjustability is key—you'll want dimmer light in the evening and brighter illumination during daylight hours.
Monitor light bars are designed for task lighting, not room illumination. They work best supplementing overhead lighting or in dimly lit environments. If working in complete darkness, the contrast between your lit desk and dark room can still cause eye strain. Some models like the BenQ ScreenBar Halo include backlighting to reduce this contrast.
After testing multiple models and analyzing thousands of user reviews, our recommendations are clear. For professionals who spend long hours at their desk and want the absolute best experience, the BenQ ScreenBar Halo 2 justifies its premium price with superior lighting quality, wireless control, and bias lighting features.
The Xiaomi Mi Computer Monitor Light Bar offers the best value proposition—delivering premium features at mid-range pricing. It's our top recommendation for most users seeking excellent performance without breaking the bank.
Budget-conscious buyers will find the Quntis Monitor Light Bar Pro+ delivers impressive features and performance for around $40-60. It's particularly well-suited for curved monitors and offers auto-dimming at a fraction of the cost of premium alternatives.
The Baseus Monitor Light Bar provides basic functionality for those on tight budgets, though its limitations in glare control and memory functions may frustrate some users.
Whatever your choice, adding a monitor light bar to your workspace will reduce eye strain, improve visibility, and create a more comfortable working environment. The investment in proper lighting pays dividends in productivity and long-term eye health.
