A monitor light bar makes the most sense when you want to see the keyboard, a notebook, and the usual mess around them without giving up another patch of desk. The good ones direct light forward instead of washing the screen. The bad ones are ordinary LED tubes with optimistic product photos.
My short list has four models. The Quntis Focus PRO+ is the value pick, the Xiaomi Mi is the tidy alternative, the BenQ ScreenBar Pro has the best documented fit and coverage, and the BenQ ScreenBar Halo 2 is the expensive dark-room option. You do not need to spend BenQ money to get useful controls.

The prices need context. Quntis listed the Focus PRO+ at US$69.99, while its Canadian Amazon listing was CA$89.99. Best Buy Canada listed the Xiaomi at CA$74.99. Best Buy listed the BenQ ScreenBar Pro at US$139 and the Halo 2 at US$199, with the latter at CA$249.99 in Canada. Treat those as a snapshot, not a promise.
What a Monitor Light Bar Actually Does
A light bar sits on the top edge of a display and aims an asymmetric beam at the work surface. That last word matters. A normal lamp throws light in several directions. A proper screen bar uses a reflector or lens to keep the bright part of the beam below the display and out of your eyes.
This is task lighting, not a medical device. The Canadian Centre for Occupational Health and Safety says good office lighting provides enough illumination to see documents without excessively high levels that create glare. OSHA’s workstation guidance also recommends shielded task lighting and warns that bright sources reflected in a screen can make it harder to see.
A bar can light the keyboard and papers while leaving more room for a mouse or notebook. It cannot fix poor screen brightness, tiny text, or a window reflected in the panel. Start with sensible monitor colour settings, then decide whether the desk itself needs more light.
Best Value: Quntis Focus PRO+
The Quntis Focus PRO+ in Canada puts the useful features near the budget end of this list. The 51 cm bar has a wireless dial, stepless brightness, 3000K to 6500K colour adjustment, automatic dimming, setting memory, and a two-hour timer. Quntis specifies USB-C power at 5V/1A and includes a 1.8 m USB-A-to-USB-C cable, not a wall adapter.
The weighted mount adjusts for flat or curved monitors from 0.12 to 2.36 inches thick. That is a much broader published range than the original BenQ ScreenBar. The 45-degree lamp adjustment should also make it easier to move the cutoff away from a glossy panel. Quntis claims at least 1,200 lux, but manufacturer lux figures are difficult to compare when measurement height and lit area differ.
The compromise is polish. The mount is bulky, the lowest colour temperature is 3000K rather than 2700K, and the remote needs two AAA batteries. Quntis says most webcams can work with the bar, but it does not include the dedicated webcam shelf BenQ supplies with its newer models. Measure the top bezel and look at the rear housing before trusting the phrase “fits most.”
- Buy it for: the strongest feature-to-price ratio and a desk-level remote.
- Skip it for: the cleanest webcam installation or the warmest 2700K light.
Best Simple Remote: Xiaomi Mi Computer Monitor Light Bar
The Xiaomi Mi light bar in Canada is the neatest step up from a touch-only budget bar. Xiaomi’s puck switches the light, changes brightness, and adjusts the 2700K to 6500K colour range without making you reach over the display.
The 44.8 cm housing is the shortest of these picks. Xiaomi specifies 5W power from a 5V/1A USB connection and a 40-degree adjustable axis. Its published clamp range is 1 to 32 mm, so this is not the model to buy for an unusually thick monitor. The product page says it works with curved screens, but the generic counterweight mount is less convincing for a tight 1000R curve than a mount designed around that radius.
There is no ambient-light sensor, backlight, app, or presence detection. That is not a major loss if you set it once and use the dial. The bigger issue is regional support: North American stock often comes through marketplace sellers rather than a consistent first-party channel. Check who fulfils the order and what return policy applies.
- Buy it for: a compact bar, a good wireless dial, and full 2700K to 6500K adjustment.
- Skip it for: thick monitor housings, automatic dimming, or dependable first-party Canadian stock.
Best Overall: BenQ ScreenBar Pro
The BenQ ScreenBar Pro in Canada makes the fewest compatibility demands. BenQ specifies flat screens 0.43 to 6.5 cm thick and curved displays from 1000R to 1800R. The 50 cm lamp covers a stated 85 by 50 cm area at 500 lux, much wider than the original ScreenBar’s 60 by 30 cm claim.
Controls live on the bar. There are 16 brightness levels, eight colour settings from 2700K to 6500K, auto dimming, and an ultrasonic sensor that switches the lamp as you arrive or leave. The box includes a webcam accessory and a 15W USB-C wall adapter. You can instead use a sufficiently powerful USB-C port, but BenQ warns that weak power can reduce maximum brightness or cause flicker.
This is the best monitor light bar here for a large curved or ultrawide display if you do not need rear bias lighting. It has the broadest clearly documented fit, strong desk coverage, and a practical webcam mount. Its weakness is price. Touching a 50 cm lamp to change every setting is also less pleasant than turning a puck beside the keyboard.
- Buy it for: broad monitor compatibility, wide task lighting, and an included power adapter.
- Skip it for: a wireless controller or the lowest cost.
Best for a Dark Room: BenQ ScreenBar Halo 2
The BenQ ScreenBar Halo 2 in Canada adds the feature that can justify a premium: a rear light. It raises the illumination behind the monitor while the asymmetric front lamp lights the desk. That makes it the most complete option for somebody who otherwise works in a dark room.
Both sides offer stepless brightness adjustment, and the backlight shares the full 2700K to 6500K range. The rechargeable wireless control panel has a display. Automatic dimming and presence detection are included. BenQ rates the bar for 0.43 to 6 cm monitor thickness and 1000R to 1800R curves, and supplies a webcam mounting accessory plus a USB-C power adapter.
The problem is a CA$249.99 or US$199 bill for a lamp. If the wall is close behind the monitor and you regularly work after dark, the rear light has a real job. In a bright room, or with a monitor several feet from the wall, it becomes an expensive halo with little surface to illuminate. The standard Halo remains available in places, but the Halo 2 has wider coverage, stronger published compatibility, and a rechargeable rather than AAA-powered controller.
- Buy it for: front and rear lighting, excellent controls, and a dark setup near a wall.
- Skip it for: daytime use or any desk where US$199 sounds absurd for a light.
What About the Original BenQ ScreenBar and Baseus?
The original BenQ ScreenBar established the category and still has sound fundamentals: a 45 cm bar, touch controls, automatic dimming, 2700K to 6500K settings, Ra 95 colour rendering, USB power, and asymmetric optics. Its published fit is now narrow at 1 to 3 cm, with support listed for 1800R curves. The newer Pro covers a much wider desk and accommodates more monitor shapes. Unless the original is heavily discounted, I would buy the Pro.
The first ScreenBar Halo also has front and rear light plus a wireless dial. It is still capable, but its controller takes three AAA batteries, its 500-lux coverage is 63 by 40 cm, and regional pricing can sit too close to the Halo 2. A substantial clearance price could change the result. At a small discount, the successor is easier to defend.
Baseus sells the i-wok line at the cheap end. The i-wok 2 is roughly 46 cm wide, USB powered, and usually offers adjustable brightness and three colour settings. I left it out because current Canadian and US stock is scattered across import marketplaces, while Baseus does not maintain a useful North American specification and compatibility page for it. Low price is not enough when the clamp is the part most likely to make a light unusable.
Check the Fit Before Buying
Do not start with screen size. Start with the top edge. Measure the monitor’s thickness where the mount will sit, then look for a rear bulge, cooling vent, port, or ridge that prevents a counterweight from resting flat. A display can be only 12 mm thick at its edge and 55 mm thick where the clamp actually lands.
Curvature is the next check. A 1800R screen is gentler than a 1000R screen, and a flat front clip can press awkwardly on the latter. The BenQ Pro and Halo 2 explicitly cover 1000R to 1800R displays. Quntis says its adjustable mount supports curved monitors but does not publish a radius range on the Focus PRO+ page.
Then account for the camera. A webcam and monitor light bar both want the centre of the top bezel. BenQ includes an accessory with the Pro and Halo 2. With the cheaper models, you may need an independent arm or an offset position. Built-in monitor cameras can also be blocked by the front lip, even when the light itself fits.
Finally, inspect power. A monitor’s USB port may shut off with the display or may not supply the current a light expects. That behaviour is handy if you want the lamp to follow the computer. It is annoying if you want to use the bar for paper while the screen sleeps. A wall adapter is the reliable route, but it consumes another outlet.
Monitor Light Bar vs Desk Lamp
In a monitor light bar vs desk lamp decision, choose the light bar for a shallow desk and a fixed computer setup. It occupies no work surface, puts controls within reach, and directs an even strip across the keyboard. It is especially useful when a normal lamp would have to sit close to the screen and create a bright reflection.
Choose a desk lamp when you need to move the beam. A good articulated lamp can illuminate a book, drawing, soldering project, or video call from several angles. It can also provide light when the monitor is off. One lamp can serve more jobs, while a monitor bar is better at exactly one.
A rear wall lamp or bias light is a third option. It reduces the harsh jump between a bright display and a dark room without lighting the keyboard. That may be all you need if the desk surface is already visible. The Halo 2 combines both approaches, then sends you the corresponding invoice.
Who Should Skip a Monitor Light Bar
Skip this category if you need ambient room light. A front-facing bar should not throw enough light around a whole room, because that would undermine its controlled beam. Buy a floor lamp, shaded desk lamp, or indirect wall light instead.
Skip it if your monitor has an unusually thick or irregular back and the manufacturer does not confirm the fit. The same applies to a laptop on a stand, a large top-mounted webcam, or a display with vents along the top edge. A clamp that technically closes can still cover pixels, stress a thin bezel, or wobble every time the desk moves.
It is also the wrong fix for uncomfortable text or a poorly positioned display. Work through the ergonomic desk setup checklist and consider a monitor chosen for comfortable viewing before asking a lamp to solve a screen problem.
Our pick: The BenQ ScreenBar Pro is the best choice here because it offers the most balanced set of trade-offs in this group.

Monitor Light Bar FAQ
Do monitor light bars cause screen glare?
A well-aimed asymmetric bar should keep direct light below the display. Glossy screens can still show reflections if the bar is rotated too far back, and cheap optics can spill light upward. Test the darkest area of the screen after installation and rotate the beam forward if you see the LEDs or a bright strip.
Can a monitor USB port power the light?
Often, yes, if the port meets the stated current requirement. Xiaomi and Quntis specify 5V/1A. BenQ rates the ScreenBar Pro up to 5V/1.7A and includes a wall adapter. A weak port can limit brightness or cause flicker, so use the supplied adapter when one is included.
Will a light bar fit a curved monitor?
Some will. Match the product’s stated curvature range and thickness clearance to the actual display. The ScreenBar Pro and Halo 2 explicitly support 1000R to 1800R curves. A generic “curved compatible” claim is less useful than those measurements.
Is the BenQ ScreenBar Halo worth it?
The current Halo 2 is worth considering if you work near a wall in a genuinely dark room and want front task lighting plus adjustable rear light in one unit. If the room is already lit, the ScreenBar Pro or Quntis does the main job for less.
The Short Version
Buy the Quntis Focus PRO+ if you want the useful parts of a monitor light bar without the premium bill. Choose the Xiaomi Mi for a compact design and simple wireless dial. Pay for the BenQ ScreenBar Pro when fit, wide coverage, and an included webcam mount matter more than price. Reserve the Halo 2 for a dark room where its rear light will actually hit a wall and do some work.
Measure the monitor where the clamp sits, plan around the webcam, and decide whether you need task light or room light. That ten-minute check matters more than another ten product features.
