Why you should trust this review
BenQ is the Taiwanese display and lighting brand best known for the PD2725U monitor. The ScreenBar Halo is the company’s flagship monitor light, sitting one tier above the original ScreenBar that defined the monitor-light category in 2018.
I review home office gear and used the ScreenBar Halo on a 27 inch Apple Studio Display from December 2025 through May 2026. The unit was purchased at retail with a BenQ direct order. The company did not provide a sample.
How we tested the ScreenBar Halo
- 200 hours of daily use on a 27 inch Apple Studio Display

Who should buy the BenQ ScreenBar Halo
Buy the ScreenBar Halo if:
- You work long hours at a monitor and eye strain is a real concern.
- Your wall behind the monitor is dark (the rear backlight reduces contrast strain).
- You have a 24 to 32 inch flat-back monitor.
- You appreciate a wireless controller for adjustments.
Skip it if:
- You have a curved monitor with a top-edge frame thicker than 2.4 inches.
- Your budget is under $130. The BenQ ScreenBar Original covers most of the use case for $50 less.
- You only need ambient light. The Xiaomi Mi LED Desk Lamp Pro is the right pick at $79.
Front LEDs: the keyboard shadow fix
The ScreenBar Halo’s front LEDs project a wide light beam onto the desk surface in front of the monitor. The beam covers the keyboard and the surrounding desk area without putting any light on the monitor screen.
This is the single feature that justifies a monitor light over a desk lamp. A traditional desk lamp creates a shadow when your hands move over the keyboard, which is distracting and adds eye-strain workload. The ScreenBar Halo’s wide beam from above the monitor eliminates the shadow entirely.
In testing, the difference is obvious within an hour of use. Reading a document on the desk in front of the monitor is noticeably easier with the ScreenBar Halo than with the room overhead light alone. The front LEDs hit 800 lumens at peak, which is enough for any office use case.
Rear backlight: the eye strain reduction
The ScreenBar Halo’s rear LEDs project a soft 200 lumen wash on the wall behind the monitor. This reduces the contrast between the bright monitor and the dark wall, which is a known source of eye fatigue over long sessions.
In testing, the rear backlight is most useful in a dark home office where the wall is matte and dark colored. The contrast reduction is real, eye strain after a 4-hour session is measurably lower than with the front LEDs alone. The original ScreenBar (without the rear backlight) cannot match this benefit.
The trade-off is over-brightness in some settings. If your wall is light colored or your room has strong overhead lighting, the rear LEDs can feel like too much. The wireless controller lets you turn them off independently of the front LEDs, which solves the problem.
Wireless puck controller: the convenience win
The ScreenBar Halo ships with a wireless puck controller that connects via a proprietary 2.4 GHz link (no Bluetooth or app required). The puck includes a brightness dial, a color-temperature dial, an auto-dim toggle, and a power button.
The convenience versus a touch panel above the monitor is significant. The original ScreenBar’s touch panel requires you to reach past the monitor to adjust brightness, the Halo’s puck sits on the desk where you can reach it without moving. For frequent adjustments through the day, the puck saves real time.
Build quality and the 2-year warranty
BenQ’s 2-year warranty covers manufacturing defects in the LEDs, the controller, and the mount. The unit shows no LED failures or color-shift in the test period or in the long-term Amazon reviews.
The aluminum housing is finished to match a typical Apple or Dell monitor aesthetic. The counterweight clip mount holds the unit at the top of the monitor without requiring a screw clamp, which means no marks on the monitor frame and no risk of overtightening damage.
The USB-A power cable is a minor annoyance for USB-C-only setups (most modern MacBook Pros). A USB-A to USB-C adapter solves this for $8 on Amazon. BenQ has not yet released a USB-C variant of the Halo, which is a reasonable complaint at the $169 price point.

Should you buy the BenQ ScreenBar Halo Monitor Light?
The BenQ ScreenBar Halo is the monitor light you buy when you actually want to be able to see what you are reading without staring into your own desk lamp. The front LEDs eliminate keyboard shadow, the rear backlight reduces eye strain on dark walls, and the wireless puck controller is more useful than any in-line touch panel. It costs more than the original ScreenBar and the rear LED can be too bright in some settings, but for a setup with a 27-plus inch monitor the Halo is the category leader.
Frequently asked questions
Is the BenQ ScreenBar Halo worth $169 in 2026?+
Yes, particularly compared to a desk lamp. The front LEDs reduce keyboard shadow without putting glare on the screen, which a traditional desk lamp cannot do. For a budget alternative, the [BenQ ScreenBar Original](/reviews/benq-screenbar-monitor-light) saves $50 by skipping the rear backlight.
ScreenBar Halo vs ScreenBar Original: which is better?+
The Halo wins on the rear backlight (reduces eye strain on dark walls), the wireless controller (more accessible than a touch panel above the monitor), and the auto-dimming sensor. The Original wins on price by $50. For a setup with a dark wall behind the monitor pick the Halo, for a light-wall setup the Original is enough.
Will the Halo fit a 32 inch curved monitor?+
Possibly. The mount uses a counterweight clip rather than a clamp, designed for monitor backs from 0.4 to 2.4 inches thick at the top edge. Curved monitors with thicker frame edges (over 2.4 inches) will not fit. Verify your monitor's top-edge thickness against the spec before ordering.
How does the wireless puck controller work?+
The puck connects to the light bar via a 2.4 GHz wireless link (no Bluetooth or app required). It includes a brightness dial, a color-temperature dial, an auto-dim toggle, and a power button. The puck runs on a single AA battery that lasts about 12 months in normal use. The convenience versus a touch panel above the monitor is significant, you can adjust without reaching past the screen.
