Description
The BenQ ScreenBar utilizes a precision-engineered asymmetric optical design to illuminate the desk surface without casting light directly onto the monitor screen, effectively eliminating reflective glare. This USB-powered LED lamp is constructed from high-quality aluminum alloy and polycarbonate, featuring a patented weighted clip that attaches to monitors without tools. By meeting IEEE PAR1789 flicker-free standards and minimizing blue light hazards, it provides a stable and safe light source for professional environments.
This product is for:
- Software developers and engineers who require consistent, glare-free lighting for extended coding sessions in dark or variable light environments.
- Graphic designers and digital artists who benefit from high color rendering (CRI >95) to ensure accurate color perception on their workspace.
- Remote professionals and office workers looking to maximize desk real estate by replacing traditional bulky desk lamps with a monitor-mounted solution.
- Students and researchers who spend long hours reading digital documents and need adjustable color temperatures to mitigate visual fatigue.
- Financial analysts and data entry specialists who require focused task lighting on physical documents while maintaining screen clarity.

Operating the ScreenBar is intuitive via touch-sensitive controls located on the top of the bar, allowing for manual adjustment of brightness and color temperature across eight ANSI levels. The 'Auto-Dimming' mode is the core functional highlight, utilizing a built-in sensor to detect ambient light levels and instantly calibrating the output to the recommended 500 lux standard. Its space-saving design ensures that the workspace remains uncluttered, while the high-quality LED components prevent the flickering and blue light exposure common in lower-end lighting products.
While traditional desk lamps often create hotspots and screen reflections, the ScreenBar's directional light path ensures the monitor remains dark while the keyboard and documents are brightly lit. Compared to the ScreenBar Plus, which features a desktop dial, or the ScreenBar Halo, which includes wireless controls and backlighting, this original ScreenBar offers the most streamlined, cable-free aesthetic. It is specifically optimized for flat monitors and 1800R curved screens; however, users with 1000R to 1500R curved displays may prefer the ScreenBar Pro or Halo models for better fitment.
Will the ScreenBar fit my specific monitor? The ScreenBar is designed for monitors with a thickness between 1cm and 3cm. It is compatible with most standard flat-panel displays and 1800R curved monitors, though it is not recommended for use with laptops due to the weight and clip design.
How does the auto-dimming function work? The integrated ambient light sensor monitors the surrounding environment. When activated, it automatically adjusts the lamp's brightness to reach 500 lux, which is the recommended illumination level for office work, ensuring your eyes don't have to compensate for poor lighting.
Can I adjust the color of the light? Yes, the ScreenBar offers 8-step ANSI White color temperature adjustments ranging from a warm 2700K (ideal for relaxation and evening use) to a cool 6500K (ideal for focus and productivity).
What are the power requirements for this device? The ScreenBar is powered via a 5V/1A USB port. You can plug it directly into your monitor's USB port, your computer, or a standard USB wall charger. Using a port with less than 1A may result in flickering or reduced brightness.
Q&A:
Is this light bar safe for my eyes? Yes, the BenQ ScreenBar is certified flicker-free and has passed blue light hazard testing. The asymmetric optical design specifically prevents light from hitting the screen, which is the primary cause of eye-straining glare in digital workspaces.
