The core factor that separates the BenQ ScreenBar Halo from generic or budget light bars is its patented Asymmetrical Optical Design. The LED strip is calibrated at a precise angle, ensuring light is directed only onto the workspace and keyboard area without hitting the monitor. The result is 100% elimination of screen glare, the primary cause of eye fatigue during long hours of work or gaming.
Furthermore, the lamp housing features an anti-reflective coating inside its aluminum shell to deliver a soft, uniform beam with a Color Rendering Index (CRI) of Ra > 95. This near-natural light quality ensures that graphic design, photo editing, and color-sensitive tasks remain perfectly accurate.
Smart Controls and Real-World Functionality
High-Precision Wireless Controller
The BenQ ScreenBar Halo comes with a luxurious, circular 2.4GHz wireless controller, allowing you to adjust lighting without reaching for the lamp and causing the monitor to wobble. The controller features a motion sensor that wakes the LED interface as your hand approaches. It utilizes intuitive touch controls combined with an industrial-grade bearing ring for smooth, precise adjustment of brightness (dimming) and color temperature.
Eye-Care Backlight Mode
A key feature that places the Halo above the ScreenBar Plus is the integrated rear backlight. You can toggle between three modes: front light only, rear light only (for a relaxing nighttime ambiance), or both simultaneously. This backlight reduces the contrast between the screen and the surrounding wall, preventing your pupils from working too hard when shifting your gaze.
Auto-Dimming System
Equipped with an Ambient Light Sensor, the device detects room lighting in real-time and automatically adjusts the lamp’s brightness to the optimal 500 Lux, the internationally recognized standard for maximum visual efficiency and eye comfort.
Premium Build and Curved Monitor Compatibility
The BenQ ScreenBar Halo is crafted from space-gray, sandblasted aluminum alloy and premium polycarbonate. Its patented clamp is mechanically engineered to securely grip the monitor without adhesives or screws, and it is designed to avoid obstructing most external webcams.
For curved monitors with a curvature ranging from 1000R to 1800R, BenQ includes a specialized adapter in the box. This accessory increases the distance between the lamp and the screen, preventing the edges of the lamp from touching or obscuring the corners of the monitor, ensuring symmetrical light distribution across your entire desk.

Frequently Asked Questions (FAQ)

Yes, the included Curved Adapter supports various screen thicknesses and curvatures up to 1000R perfectly, ensuring it stays secure without vibrating.
2. Why does the lamp flicker or the backlight fail to turn on sometimes?
This is usually due to insufficient power from the motherboard or monitor USB port. We recommend plugging the USB cable into a dedicated power adapter (at least 5V/1.5A) for maximum stability.
3. How long does the wireless controller battery last?
With normal use (adjusting lighting 4-5 times a day), the 3x AAA batteries in the wireless controller will last approximately 6-12 months thanks to the power-saving Sleep Mode.
