Manufacturer description
The BenQ ScreenBar Halo 2 is a monitor light bar built for people who work in dim rooms and can't afford glare on the panel. Its ASYM-Light front lighting throws desk illumination at an 18-degree anti-glare angle, so the beam lands on your keyboard and notes instead of bouncing back off your screen. Behind the bar, an adjustable ambient backlight softens the contrast between a bright display and a dark wall, which is the part most competing bars leave out. You get a stepless brightness range and 2700K to 6500K color temperature, driven by a wireless dial with a built-in readout showing the…
SpecPicks Verdict
SpecPicks scored BenQ ScreenBar Halo 2 LED Monitor Light Bar using a rating × review-volume × price-fit model applied to published specs and reviews across the rgb & lighting category. BenQ's rgb & lighting lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for rgb & lighting of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
Will the ScreenBar Halo 2 fit my curved monitor?
Yes, if the curvature is between 1000R and 1800R. The clamp also needs a top bezel between 0.17 and 2.36 inches (0.43 to 6 cm) thick. It mounts without screws or adhesive, so it does not damage the panel.
How is this different from a regular monitor light bar?
Two things: the rear ambient backlight, which most bars omit, and ASYM-Light front optics that aim light at an 18-degree anti-glare angle. Together they reduce both screen reflections and the contrast gap between a bright display and a dark room.
Can I use it for photo or video editing without skewing colors?
BenQ rates it at CRI above 95 for true-to-life color rendering and states the Halo 2 was tested so it does not affect color calibration work. Check the product listing for the specific calibration conditions BenQ tested.
Do I have to turn it on and off manually?
No. It turns on and off automatically with your monitor, adjusts brightness to ambient room light on its own, and the My Favorite mode recalls your last brightness and color temperature settings.
How long do the LEDs last, and is it safe for long sessions?
BenQ rates the LED lifespan at over 50,000 hours without dimming or flickering. The LEDs are flicker-free and blue-light-hazard-free, with glare-free illumination aimed at reducing fatigue during extended screen time.
