How We Compared These Monitor Light Bars
This is a specification-based comparison using BenQ’s current US product pages and published technical specifications. Beglance has not conducted independent laboratory measurements of these lights, so the brightness, fit and comfort observations below are based on their documented designs rather than claimed personal testing.
Before ordering either model, inspect the top and back of your monitor. Thickness and curvature measurements are useful, but a large rear housing, built-in webcam, unusually narrow bezel or another mounted accessory can also affect compatibility.

The Biggest Difference: Rear Ambient Lighting
The most important difference in the BenQ ScreenBar Halo 2 vs ScreenBar Pro comparison is the light behind the monitor.
ScreenBar Halo 2 combines a front task light with a tri-zone rear backlight. The backlight illuminates the wall behind the display, helping reduce the strong visual contrast between a bright monitor and a dark room. Both the front and rear lights support adjustable brightness, while the backlight also provides color-temperature adjustment from 2700K to 6500K.
ScreenBar Pro provides front-facing desk illumination only. It does not project ambient light behind the monitor. This simpler design makes sense when the room already has adequate background lighting or when you want a clean, distraction-free workspace.
Importantly, Halo 2’s rear light is adjustable white light—not RGB gaming lighting. If you want multicolour effects synchronized with games, neither of these BenQ models is designed primarily for that purpose.
Front Lighting and Desk Coverage
The two models are closely matched on published front-light performance. BenQ specifies center illumination above 1,000 lux at a height of 50 cm for both products. It also publishes an 85 × 50 cm area receiving at least 500 lux for each model.
Both use asymmetric optical designs intended to direct light toward the desk instead of reflecting it directly from the display. This allows the keyboard, mouse, notebook and nearby documents to remain illuminated without placing a traditional lamp beside the monitor.
Both models also publish a front-light color rendering index of Ra 95 or higher and a color fidelity index of Rf 96 or higher. These numbers indicate similar documented color-rendering performance for ordinary office work, reading and creative tasks.
Because their published front-light specifications are so similar, maximum brightness alone should not decide your purchase. The room environment and preferred control method are more meaningful differences.
Controls: Wireless Dial vs Integrated Touch Panel
ScreenBar Halo 2 Controls
Halo 2 uses a rechargeable wireless controller placed on the desk. Its digital touch panel adjusts brightness and color temperature and switches between front and rear lighting controls.
BenQ states that the controller can last up to three months on one charge. A single controller can also be paired with two Halo 2 units, which may be useful for a coordinated dual-monitor arrangement.
The controller is convenient when the monitor is large, mounted high or positioned beyond comfortable reach. However, it occupies a small amount of desk space and adds another device that requires occasional charging.
ScreenBar Pro Controls
ScreenBar Pro places its touch controls directly on the light bar. You can adjust brightness, color temperature, automatic dimming and presence-sensing functions without a separate controller.
This approach keeps the desk cleaner and removes the need to charge a remote. The tradeoff is that you must reach toward the top of the monitor whenever you want to make a manual adjustment.
Controls verdict: Choose Halo 2 if you frequently change settings and want convenient desk-level controls. Choose ScreenBar Pro if you prefer fewer accessories and usually leave automatic settings enabled.
Automatic Dimming and Presence Detection
Both models include automatic dimming that responds to surrounding light conditions. This helps maintain a suitable workspace brightness without repeatedly adjusting the lamp manually as daylight or room lighting changes.
Both also use an ultrasonic sensor for presence-based operation. BenQ states that the sensor detects movement in front of the screen, turns the light on when you arrive and can switch it off after five minutes without significant movement.
Presence sensors are convenient, but users who sit very still may occasionally prefer to disable automatic shutoff. Both products remain usable as manually controlled monitor lights.
Curved and Ultrawide Monitor Compatibility
BenQ publishes support for monitor curvatures from 1000R to 1800R for both Halo 2 and ScreenBar Pro. That range covers many curved gaming and ultrawide displays.
The Halo 2 clamp supports monitors measuring approximately 0.43–6 cm thick. ScreenBar Pro extends the upper limit slightly to 6.5 cm. That extra 0.5 cm may matter when a monitor has a particularly deep top-center housing.
Both clamps use padded contact areas intended to secure the light without scratching the monitor. Their front contours are also shaped to avoid covering many built-in camera lenses.
Compatibility is not guaranteed by screen size alone. Measure the monitor at the exact top-center mounting position rather than relying only on its advertised depth. Also check whether the rear casing has a sharp slope, ventilation opening or central bulge.
Compatibility verdict: Both are strong choices for curved monitors, but ScreenBar Pro has the slightly broader published thickness range.
Color Temperature and Visual Comfort
Both monitor lights offer settings from warm 2700K light to cooler 6500K light. Warm settings can create a softer atmosphere during evening use, while neutral or cooler settings may suit daytime work and tasks where clearer white illumination is preferred.
Halo 2 allows stepless adjustment for its front and rear lighting system. ScreenBar Pro provides eight documented color-temperature levels. Most users should be able to find a practical setting on either model, although Halo 2 offers more granular control.
A monitor light bar should illuminate the desk rather than make the screen itself brighter. Adjust the output so it complements the monitor and room instead of creating another overly bright light source.
Power and Desk Setup
Both models use USB-C power, but their maximum consumption differs. BenQ lists a maximum of 15W for Halo 2 and 8.5W for ScreenBar Pro. Halo 2 requires more power because it operates both the front task light and rear backlight.
Use the supplied power equipment or a source that meets BenQ’s specifications. Avoid assuming that every monitor USB port can provide the required output, particularly when powering the Halo 2 at higher brightness.
Neither light occupies the main desk surface because both mount on the monitor. Halo 2 adds its wireless controller to the desk, while ScreenBar Pro keeps all controls on the lamp.

Which One Offers Better Value?
Prices and promotions change, so the better value depends on which features you will actually use.
ScreenBar Pro provides the core front-lighting features shared by both models: strong published illuminance, wide desk coverage, adjustable color temperature, automatic dimming, presence detection and curved-monitor support.
Halo 2 adds two practical benefits: a tunable rear backlight and a rechargeable wireless controller. Those additions can justify the premium for people who work at night, use a dark room or adjust their lighting frequently.
If rear ambient lighting will remain switched off most of the time, ScreenBar Pro is likely the more sensible purchase. If the wall behind your display is usually dark, Halo 2 offers the more complete lighting system.
BenQ ScreenBar Halo 2 vs ScreenBar Pro: Final Verdict
ScreenBar Halo 2 is the better choice for dim-room users because it combines strong front lighting with a tunable rear backlight and convenient wireless controls.
ScreenBar Pro is the better choice for users who primarily need broad, automatic desk illumination and do not want to pay for or manage rear lighting.
Their published front-light brightness, coverage and curved-monitor compatibility are very similar. Therefore, do not choose based on the larger-looking product name. Decide whether rear ambient lighting and a wireless controller genuinely improve your workspace.
