Pros
- Completely glare free on screen with even, flicker free desk coverage
- Excellent color rendering with CRI over 95, tested not to interfere with calibration work
- Premium aluminum build with stable clamp that fits flat and curved monitors
- Intuitive wireless controller with auto dimming, motion activation and memory for favorite settings

The BenQ ScreenBar Halo 2 is a USB powered LED bar that clamps to the top of your monitor to light your desk without glare. It is designed for remote workers, students, coders, gamers and visual creators who spend long hours in front of a screen.
Its dual lighting system pairs a glare free front light with a wide ambient backlight to balance brightness around your display. In daily use, the front beam stays off the screen while the back glow reduces eye fatigue, and stepless brightness plus 2700K to 6500K temperature make it easy to tune for day or night.
Build quality feels premium with an aluminum bar, polished dark grey finish and a sturdy clamp that fits flat and 1000R to 1800R curved monitors. The wireless dial controller sits neatly on the desk and shows exact values, so adjustments feel precise and effortless.
It is not perfect, as the slim front beam can feel focused and stark compared to a diffuse desk lamp. Some users also wish the backlight threw further down the wall, and you still need to route a USB cable for power.
Overall, the Halo 2 is one of the most polished and eye friendly monitor lights you can buy for focus and comfort. If you want accurate color, smart auto features and zero screen glare in a clutter free setup, it is an excellent upgrade.
Model: BenQ ScreenBar Halo 2 in Dark Grey with minimalist aluminum bar and polished finish. Mounts on top of monitors 0.17 to 2.36 inches thick, including 1000R to 1800R curved screens.
Lighting: Dual front and back LED system with stepless brightness, 2700K to 6500K color temperature, CRI over 95, flicker free and blue light hazard free output.

The Quntis Computer Monitor Lamp is a USB powered light bar designed to sit on top of your monitor and light your workspace without lighting your screen. It is built for students, office workers, designers and gamers who spend long hours at a desk and want more comfortable lighting.
Its standout feature is the asymmetrical optical design that directs light downward onto the desk, eliminating reflections and screen glare. The built in ambient sensor auto adjusts output to maintain balanced illumination, while stepless dimming and 3000K to 6500K color tuning let you shift from warm reading light to cool focus light.
In daily use, the 78 LED array with Ra98 color rendering produces even, natural looking light with minimal shadows. Colors look accurate and text is easier to read, which is especially helpful for design work, studying and late night sessions with reduced eye strain.
Build quality is solid with a slim lacquered aluminum bar and a weighted clip that mounts securely without tools. Touch controls are responsive, USB power keeps wiring simple, and the compact profile saves valuable desk space compared to a traditional desk lamp.
It is not perfect, as it needs constant USB power and the clip may not fit every ultra thin or curved display perfectly. Overall, this is a practical, eye friendly upgrade for any home office setup that delivers focused, customizable light where you need it most.
Finish and Build: Lacquered aluminum light bar with weighted monitor clip for stable, tool free mounting.
Lighting Specs: 78 LED beads, 3000K to 6500K adjustable color temperature, stepless brightness with auto dimming sensor.
Eye Comfort Features: Flicker free output, low blue light design, asymmetrical optics for no screen glare, ultra high Ra98 color rendering.
Size and Power: 15.7 inch wide, 0.78 inch slim profile, USB powered with touch controls for easy operation.
How They Compare
Light Coverage: Front Task Light Versus Front Plus Rear Glow
The BenQ ScreenBar Halo 2 LED Monitor Light Bar combines a front task beam with a wide adjustable rear backlight for wall wash. Its ASYM-Light Technology directs front light at an 18° anti-glare angle so your keyboard gets bright light while your screen stays free of reflections. The Quntis Computer Monitor Lamp uses an asymmetrical optical design that also lights only your desk area, enhancing focus without shining into your eyes or bouncing off the panel.
That rear glow is the biggest experiential gap in BenQ ScreenBar vs Quntis screen light bar. The BenQ ScreenBar Halo 2 LED Monitor Light Bar softens the edge between a bright game and a dark room, which owners commonly report feels easier during long horror or RPG sessions. The Quntis Computer Monitor Lamp keeps things simple and directional, which can be better if your desk faces into a bright room where wall wash would be washed out anyway. Neither needs a lamp base, so both free up surface space.
Color Range, Color Accuracy and Eye Comfort
The BenQ ScreenBar Halo 2 LED Monitor Light Bar offers stepless brightness with a color range from 2700K to 6500K and a high color rendering index over CRI 95. That rendering is presented for color sensitive tasks where skin tones, prints, and game art should look true. The Quntis Computer Monitor Lamp offers stepless dimming from 3000K to 6500K with 78 LED beads and an ultra-high Ra98 rating, which is also positioned for vibrant and realistic color during reading, design, and play.
For comfort, the Quntis Computer Monitor Lamp cites IEC/TR 62778 and IEC/EN 62471 compliance for reduced blue light hazard plus flicker-free output and auto adjustment toward 900 lux. The BenQ ScreenBar Halo 2 LED Monitor Light Bar leans on reduced contrast from its backlight plus precise front cutoff to keep light out of your eyes. If you run a bright 1440p panel like the setups in our 1440p gaming PC build breakdown, the BenQ warmer 2700K low end can feel softer after midnight, while the Quntis 3000K low end still feels neutral and alert.
Controls, Auto Dimming and Everyday Convenience
Control style separates these two more than any spec line. The BenQ ScreenBar Halo 2 LED Monitor Light Bar includes a wireless dial controller with a built-in display that shows exact values for brightness, color temperature, and modes. It can turn on and off with your monitor, respond to ambient light, and recall your last look through a My Favorite mode. The Quntis Computer Monitor Lamp relies on touch control on the bar with stepless dimming and a built-in sensor that continuously tunes output.
If your tower sits on the floor or your shelf is crowded, you will likely prefer reaching for a dial instead of tapping the top of your display. Owners commonly report that auto power with the monitor removes one more switch from a nightly routine. The Quntis approach has fewer pieces to place or misplace, which suits dorms and shared offices. Both save space compared with a classic arm lamp, a plus when you are already planning clearance as described in our guide to choosing an airflow case for a hot GPU.
Fit, Curved Support and Long Term Use
The BenQ ScreenBar Halo 2 LED Monitor Light Bar uses a space-saving clamp rated for displays from 0.17 inch to 2.36 inch thick, or 0.43 to 6 cm, and curved screens from 1000R to 1800R. That stated range gives confidence if you own a deep curve or a thick rear housing. The Quntis Computer Monitor Lamp uses a weighted clip designed to sit securely on top of the monitor without tools, and it is also described as space saving, though the data we reviewed does not list a specific thickness or curve range.
For lifespan, the BenQ lists over 50,000 hours of LED life with stable output over time. The Quntis data does not list a lifespan figure, but owner sentiment is broad with 13784 ratings at 4.6 out of 5, while the BenQ holds 4.7 out of 5 from 1221 ratings. The takeaway is practical: choose the BenQ when you need documented curved fit and dial feedback, accept that the separate controller adds clutter. Choose the Quntis when you want a compact clip with touch input, accept that fit on very thick or sharply curved shells is less certain.
Which One Should You Get
Choose BenQ ScreenBar Halo 2 LED Monitor Light Bar if you play in a dark room on a curved ultrawide or a deep 1000R to 1800R panel and want both desk light and wall glow. Its 2700K to 6500K range, CRI over 95, rear backlight, and wireless dial suit 1440p story gamers, photo editors, and anyone who tweaks tone from daylight white to warm night amber. It is the higher-end pick for large desks where you already manage cable routing and case clearance like the examples in our mid tower case guide for large cooling and GPU builds. Skip it if you dislike extra accessories on your desk.
Choose Quntis Computer Monitor Lamp if you want straightforward glare-free desk light with minimal fuss. Its front only asymmetrical beam, 3000K to 6500K tuning, Ra98 color, 78 bead array, and auto dimming toward 900 lux cover homework, office documents, and competitive night sessions without a separate controller. It suits flat 1080p and 1440p monitors, student setups, and second PCs where simplicity beats fine tuning. You should pass on it if you specifically want rear ambience or a display that shows exact brightness values while you adjust.
Who Should Skip Both
If you mainly play on a laptop in different rooms, want full RGB wall sync for streaming, or need a portable lamp for travel, these bars are not ideal for your setup. Neither replaces addressable strips behind a desk or a bright overhead for camera work, and neither is the right choice for glass whiteboards or glossy photo proofing under daylight. You would be better served by dedicated bias strips, a high output desk lamp, or room lighting planned alongside your PC rather than a monitor mounted bar.
Frequently Asked Questions
Is BenQ ScreenBar Halo 2 better than Quntis for night gaming eye strain?
Both help because both keep harsh light off your screen with asymmetrical front optics and flicker-free output. The BenQ ScreenBar Halo 2 LED Monitor Light Bar adds a rear backlight that lowers contrast with a dark wall, plus a warmer 2700K low end for late sessions. The Quntis Computer Monitor Lamp auto tunes toward 900 lux, so pick it if you prefer a set and forget front light in a room with some ambient glow.
Does BenQ ScreenBar Halo 2 fit curved monitors better than Quntis?
Per the spec sheet, the BenQ ScreenBar Halo 2 LED Monitor Light Bar lists support for 0.17 inch to 2.36 inch thick panels and 1000R to 1800R curves, which covers most gaming curves. The Quntis Computer Monitor Lamp uses a weighted clip for flat and curved screens but does not publish a thickness or curve range. If you own a deep curve or a thick gaming housing, the BenQ gives you clearer certainty before you order.
Is Quntis monitor light good enough for color work compared to BenQ?
For casual editing and school design tasks, the Quntis Computer Monitor Lamp with Ra98, 78 beads, and 3000K to 6500K tuning can look vivid and consistent. The BenQ ScreenBar Halo 2 LED Monitor Light Bar counters with CRI over 95 and a wider 2700K to 6500K span aimed at photographers and designers. If color accuracy pays your bills or you edit in a dark room, the BenQ rear glow and warmer low end are worth the higher-end pick.
