What Buyers Say
Users are consistently reporting a significant reduction in eye strain and improved desk illumination compared to cheaper alternatives, especially noting the glare-free front light and the much brighter ambient backlight. The wireless controller, despite a minor wake-up delay, is a standout feature for its precise adjustments and clear display of settings. While some hoped for a "life-changing" experience, most agree it's a substantial upgrade for comfort and focus.
“Dude, I used to squint all day, but this Halo 2 thing actually works, no more light in my eyes, and that backlight is legit bright, totally worth it even if the dial sometimes sleeps on me.”

Frequently Asked Questions
Does the BenQ ScreenBar Halo 2 work with curved monitors?
Yes, it's designed to securely mount on curved monitors with a radius between 1000R and 1800R, and a thickness of 0.43 to 6 cm, without damaging the screen.
How does the wireless controller work?
The intuitive wireless dial allows you to adjust brightness, color temperature (2700K-6500K), and switch between modes, with a built-in display showing precise values for easy fine-tuning. It connects via USB-C for charging and can last up to three months on a single charge.
Does it cause glare on the screen?
No, it uses ASYM-Light Technology with an 18° anti-glare angle to illuminate your desk without reflecting on your screen or shining into your eyes.
What are the smart lighting features?
It automatically turns on/off with your monitor, adjusts brightness based on ambient light, remembers your last used settings with “My Favorite” mode, and has a motion sensor for auto on/off.
Can I use a webcam with this light bar?
Yes, it includes a mount for attaching a webcam, which is a convenient addition for users.
Is the backlight bright enough?
User feedback indicates the Halo 2's backlight is significantly brighter than the original Halo and even surpasses some dedicated ambient light strips like Philips Hue, effectively reducing contrast around your monitor.
What is the color temperature range?
You can customize the light settings from a warm 2700K to a cool 6500K, allowing you to match different times of day and tasks.
Buying Guide
When you're looking at monitor light bars, you're trying to fix eye strain from your screen being too bright compared to your desk, or glare on your screen from other lights. This isn't about lighting up your whole room; it's about creating a focused, comfortable pool of light on your workspace without hitting your monitor. Pay attention to how it handles glare and if it has a backlight to ease eye fatigue.
Anti-glare angle (18°)
This tells you how precisely the light is directed. A specific angle, like 18°, means the light hits your desk, not your screen, so you don't get annoying reflections.
Color Temperature (2700K - 6500K)
This is about the "warmth" or "coolness" of the light. Lower Kelvin (like 2700K) is warm, yellowish light, good for evening. Higher Kelvin (like 6500K) is cool, bluish-white light, good for focus during the day. A wide range lets you match your environment or mood.
Backlight
This is a separate light that shines behind your monitor, onto the wall. It reduces the harsh contrast between your bright screen and a dark background, which makes your eyes less tired over long periods.
Monitor Clamp Compatibility (0.43-6 cm thick, 1000R-1800R curved)
This is crucial to make sure the light bar actually fits your monitor. If your monitor is too thick, too thin, or too curved (or not curved enough), the clamp won't work properly, or the light might not sit right.
Alternatives
If this model doesn't fit your budget or needs, look for light bars with similar anti-glare technology and a wide color temperature range, but perhaps without the advanced backlight or wireless controller, to find a more basic option.
