The BenQ ScreenBar Pro is a USB-C powered LED monitor light designed for remote workers, programmers, creators and gamers with flat or curved setups. It sits on top of your monitor to light the desk area while keeping your workspace clean and focused.
In real world use, the ultrawide beam delivers over 1000lx central brightness with even 500lx coverage across a 33 by 20 inch area. The asymmetrical optics direct light downward onto the desk, so there is no screen reflection, no direct glare and noticeably less eye fatigue during late sessions.
Standout conveniences include adjustable brightness and color temperature plus an ultrasonic motion sensor that turns the light on when you approach and off after five minutes away. It is a thoughtful touch for shared offices and energy saving without needing to touch a switch.
Build quality feels premium with a polished aluminum bar, sturdy patented clamp and integrated control buttons. It fits monitors from 0.17 to 2.56 inches thick and 1000 to 1800R curvature, and it avoids blocking the webcam on most designs.
It is not the most compact option for very small monitors and it lacks a remote control, but for eye comfort, brightness and clean design it sets the standard. If you want pro level desk lighting without a traditional lamp, the ScreenBar Pro is an excellent upgrade.

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.

How They Compare
Front Light Output and Eye Comfort Design
Both models use asymmetric optics to light your desk while keeping glare off your screen, but their front light stories differ on paper. The BenQ ScreenBar Pro LED Monitor Light Bar (Black) is rated for over 1000lx central brightness with a 500lx range within 33″x20″ (85cmx50cm), which per the spec sheet positions it as a very bright front light for wide desks. The BenQ ScreenBar Halo 2 LED Monitor Light Bar uses precision front lighting at an 18 degree anti-glare angle to illuminate your desk without reflecting on your screen or shining into your eyes.
For you, that means the BenQ ScreenBar Pro LED Monitor Light Bar (Black) leans toward maximum desk coverage for paperwork, keyboards, and controllers spread across a wide surface. The BenQ ScreenBar Halo 2 LED Monitor Light Bar leans toward balanced comfort with a high color rendering index of CRI over 95 for true to life color, which owners commonly report as helpful for photo work and design review. If you are sensitive to harsh downlights, the Halo 2 approach may feel calmer, while the Pro approach suits very dark rooms that need raw output.
Backlight and Room Ambience
This is the clearest split between the two designs. The BenQ ScreenBar Pro LED Monitor Light Bar (Black) is described per the spec sheet as a front illumination solution with asymmetrical optics, space saving buttons, and no mention of a rear ambient light. The BenQ ScreenBar Halo 2 LED Monitor Light Bar adds a wide and adjustable ambient backlight that is designed to reduce contrast between your screen and dark surroundings to help your eyes stay relaxed and focused for longer.
If you play or work with lights off, that rear glow on the BenQ ScreenBar Halo 2 LED Monitor Light Bar can make the wall behind your monitor feel less harsh and reduce the cave effect around bright panels. The BenQ ScreenBar Pro LED Monitor Light Bar (Black) keeps the focus forward, which some competitive players prefer because there is less peripheral glow during fast matches. Owners commonly report that backlight fans leave it on low for movies and story games, while front-only fans turn the bar off sooner when they want total darkness.
Controls, Color Range and Smart Features
Control style will affect your daily use more than you expect. The BenQ ScreenBar Pro LED Monitor Light Bar (Black) integrates convenient function buttons directly on the bar for easy adjustments, and it is powered via USB-C or with the included adapter for flexible use. The BenQ ScreenBar Halo 2 LED Monitor Light Bar moves controls to an intuitive wireless dial with a built-in display showing precise values, so you can adjust brightness, color temperature, and modes from your desk without reaching up to the monitor.
On customization, the BenQ ScreenBar Halo 2 LED Monitor Light Bar lists stepless brightness levels and a wide color temperature range of 2700K to 6500K to suit different times of day and tasks. It also remembers your last used settings with My Favorite mode, turns on and off with your monitor automatically, and adjusts brightness with ambient light per the spec sheet. The BenQ ScreenBar Pro LED Monitor Light Bar (Black) counters with an ultrasonic motion sensor that detects movements within a 24″ plus or minus 4″ (60cm plus or minus 10cm) diameter range and shuts down after 5 mins of absence to save energy, which is ideal if you often walk away and forget to switch lights off.
Fit, Power and Desk Compatibility
Both bars are built to clamp on top of your display to save desk space and avoid a lamp base, but the clamp ranges are slightly different. The BenQ ScreenBar Pro LED Monitor Light Bar (Black) fits monitors 0.17″ to 2.56″ (0.43cm to 6.5cm) thick and curvature 1000 to 1800R, with a patented clamp design that accommodates monitors with special back designs or non-flat top bezel. The BenQ ScreenBar Halo 2 LED Monitor Light Bar mounts on monitors 0.17″ to 2.36″ (0.43 to 6cm) thick and 1000R to 1800R curved, without damaging the screen.
In practice, the BenQ ScreenBar Pro LED Monitor Light Bar (Black) gives you a bit more tolerance for very thick monitor housings and easy setup with no blocking to camera lens per the spec sheet. The BenQ ScreenBar Halo 2 LED Monitor Light Bar offers a long life LED with a lifespan of over 50,000 hours per the spec sheet and a clean wireless puck that needs a spot on your desk.

Which One Should You Get
Choose BenQ ScreenBar Pro LED Monitor Light Bar (Black) if you want maximum forward brightness, simple on-bar buttons, and automatic walk-away shutoff for a productivity or competitive setup. It suits wide desks, shared offices, and late study sessions where you need strong, even task light without reaching for a remote, and it pairs well with a tidy build where you already reviewed how to choose a CPU cooler for your gaming build in 2026 to keep noise low while you work. You can check the current listing here: BenQ ScreenBar Pro LED Monitor Light Bar (Black). A con to accept is the lack of a listed rear ambient light, so dark room gamers who want wall glow may find it a bit plain.
Choose BenQ ScreenBar Halo 2 LED Monitor Light Bar if you game or create in a dark room and want front plus back lighting with fine control from your desk. It suits story driven play, streaming desks, and color sensitive work where adjustable backlight, 2700K to 6500K range, wireless dial with display, and CRI over 95 matter more than raw forward punch. You can check the current listing here: BenQ ScreenBar Halo 2 LED Monitor Light Bar. A con to accept is the higher-end pick positioning and the extra controller to place, plus slightly less tolerance for very thick monitor shells compared with the Pro.
Who Should Skip Both
A monitor light bar is not ideal for everyone, even with strong ratings from owners. If you use a laptop as your primary display, rely on overhead room lighting for video calls, need bias lighting that syncs with on-screen colors for console home theater, or have a monitor with an unusual top hump that prevents a secure clamp, these bars are not the right choice and a traditional desk lamp or adhesive strip may serve you better.
