Pros & Cons

Pros

✓ Asymmetrical optics put light on the desk, not reflected glare on the screen
✓ Integrated back light cuts screen-to-wall contrast in dark rooms
✓ Wireless puck controls modes, brightness and color temp without reaching up
✓ Over 100 stepless levels plus a one-press My Favorite preset
✓ USB powered off the monitor, so no lamp base or wall outlet needed

Cons

✗ Curved monitors over 1000R are capped at 1.5 inch panel thickness
✗ Needs at least a 0.25 inch bezel, ruling out truly edgeless displays
✗ Non-planar monitor backs can prevent the clip from seating properly
✗ The 1.5m USB cable may not reach a tower or desk-mounted hub

Manufacturer description

The BenQ ScreenBar Halo is a monitor light bar that clips to the top of your display and lights your desk without throwing glare back at the screen. Its asymmetrical optical design directs light down onto your keyboard and notes, while the integrated back light washes the wall behind the monitor to cut the contrast between a bright screen and a dark room. You get three lighting modes from the wireless controller: front light, back light, or both together, with over 100 stepless brightness and color temperature levels and a My Favorite preset you can recall in one press. Power comes over USB…

SpecPicks Verdict

SpecPicks scored BenQ ScreenBar Halo 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. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Will the ScreenBar Halo fit my curved monitor?

Yes, if the curve is over 1000R and the panel is no thicker than 1.5 inches (3.8cm). Flat monitors are supported up to 2.36 inches (6cm). Either way the bezel needs to be at least 0.25 inches (0.63cm) wide, and monitors with non-planar backs may not seat the clip correctly.

Does it cause glare or reflections on the screen?

BenQ uses an upgraded asymmetrical optical design that aims light forward onto the desk instead of at the panel, so there is no reflected glare on the screen. The dimmable back light further reduces glare by raising the brightness of the wall behind the monitor.

How is it powered, and does it need a wall outlet?

It runs entirely over USB from your monitor, laptop, or dock using the included 1.5m (5.9 ft) cable. There is no power brick, lamp base, or wall outlet involved, which is how it saves desk space compared to a conventional lamp.

What can the wireless controller actually adjust?

The smart wireless controller switches between three modes (front light, back light, or front and back together) and adjusts brightness and color temperature across over 100 stepless levels. You can store a preferred combination as My Favorite and recall it in a single press.

Is it worth the price over a cheaper light bar?

The differentiators over budget bars are the rear back light, the desktop wireless controller, and the stepless 100+ level dimming. If you only need front lighting on a flat monitor, a simpler bar covers that. Check the listing for current pricing.

Key Features

INTEGRATED BACK LIGHT: Our newly integrated back light design enhances overall eye comfort, no matter in screen if you are working or relaxing entertaining. Adjust it to your preferred brightness or color temperature and then set it as “My Favorite” via the smart wireless controller according to your needs.
3 EYE CARE SETTING MODES: Its dimmable Front and Back Light complement each other to reduce glare to a minimum and increase eye comfort as much as possible. The upgraded asymmetrical optical design ensures no reflected glare on your screen.
SMART WIRELESS CONTROLLER: Customizable and stepless lighting allows you to switch modes and adjust brightness and color temperature levels. Over 100 stepless levels for work and leisure. Personalized adjustment: 3 modes (Front, Back, Front& Back Light).
SPACE SAVING: Unlike your normal desk lamp, ScreenBar Halo is powered via USB. The patented clip design mounts on top of almost any monitor, saving valuable space on your desk, no lamp base or extra wires to mess up your workspace. USB cable length is 5.9” (1.5m).
HIGH COMPATIBILITY: ScreenBar Halo is designed with its unique weighted clip to fit most monitors. It supports monitors with >=0.25" (0.63cm) bezel width and thickness up to 2.36” (6cm) for flat monitors and up to 1.5” (3.8cm) for curved monitors over 1000R. Non-planar monitor back designs may cause mounting problems.
