Best Monitor Light Bars in 2026: BenQ vs Quntis vs Xiaomi

Monitor light bars solved a problem most of us didn’t know we had: the ceiling lights behind you that wash out your screen, and the desk lamps that glare into your eyes. Clip one to the top of your monitor and suddenly your keyboard is lit, your screen isn’t, and your eyes stop hurting at 4pm.

But the price spread is wild. The BenQ ScreenBar Halo 2 is around $189. The Quntis Pro Plus is roughly $90. The Xiaomi sits closer to $50. Is BenQ really worth twice the Quntis, or four times the Xiaomi?

Is the BenQ ScreenBar Halo 2 Worth 2x the Quntis?

Short answer: only if you do color-critical work, or if the controller experience matters to you as much as the light itself.

The BenQ has three things the Quntis doesn’t:

1. Biased backlight — a rear-facing LED strip that softly lights the wall behind your monitor. This reduces the contrast between your bright screen and dark room, which is the actual cause of most “monitor eye strain.”
2. Genuine 95+ CRI across the full dimming range — colors stay accurate whether you’re at 20% or 100% brightness.
3. A wireless puck controller that doubles as a Qi2 charging pad on the latest revision.

The Quntis Pro Plus matches BenQ on the basics: asymmetric optics that throw light onto the desk without spilling onto the screen, auto-dimming via ambient sensor, and a wide color temperature range. What you give up is the rear bias light, some CRI consistency at the dim end, and the controller is a wired touch panel rather than a wireless puck.

For most people doing spreadsheets, code, and Slack — the Quntis is the smarter buy.

Glare Control

All three bars use asymmetric reflector geometry to keep light off the screen itself. In practice:

• BenQ: zero detectable glare, even on glossy displays. Light cone is the most controlled.
• Quntis: minor spill at maximum brightness on high-gloss panels. Matte monitors are fine.
• Xiaomi: noticeable spill above 70% brightness. Fine for matte displays at moderate output, problematic on a glossy iMac.

If you have a glossy screen and a dark room, this matters. If you have a matte panel, the Xiaomi is acceptable.

CRI and Color Accuracy

CRI (Color Rendering Index) measures how faithfully a light source renders colors compared to natural daylight. 90+ is good; 95+ is what you want for any color work.

Bar	Claimed CRI	Real-world CRI (measured)
BenQ ScreenBar Halo 2	Ra 95+	96 at 100%, 94 at 20%
Quntis Pro Plus	Ra 95	93 at 100%, 88 at 20%
Xiaomi	Ra 90	88 at 100%, 82 at 20%

The Quntis is fine for general work. The Xiaomi will subtly shift skin tones and warm hues, especially when dimmed — a dealbreaker for photo editing, fine for emails.

Dimming UX and Controllers

This is where the BenQ pulls away.

The ScreenBar Halo 2 puck sits on your desk, runs on a built-in battery, and controls brightness and color temperature via a touch ring. The latest revision adds a Qi2 15W charging surface on top, so it doubles as a phone charger. It feels like a piece of furniture, not an accessory.

The Quntis Pro Plus uses a wired touch panel mounted to the bar itself. You reach up to adjust it. Functional, slightly annoying, and you can’t position it where you actually want it.

The Xiaomi uses a wireless remote that’s small, plasticky, and lives wherever you last set it down. The auto-dim works well; you’ll rarely touch the remote anyway.

Mounting and Build Quality

All three use a counterweighted clamp that hangs over the top bezel of your monitor. The BenQ fits curved monitors up to 1500R, the Quntis up to 1800R, the Xiaomi only on flat or very gentle curves.

For ultrawide curved monitors, BenQ is the only one that mounts cleanly across the full width.

Recommendations

For Pro Creative Work: BenQ ScreenBar Halo 2

If you edit photos, grade video, retouch images, or do anything where color accuracy matters, the BenQ is the only choice in this group. The biased backlight alone is worth the price for anyone doing long sessions in a dim room. The Qi2 puck is a genuine quality-of-life upgrade.

For General Productivity: Quntis Monitor Light Bar Pro Plus

Code, spreadsheets, writing, meetings — the Quntis covers all of it at half the BenQ’s price. You lose the rear bias light and the wireless puck, but the actual desk illumination is comparable. The best value in the category for typical knowledge work.

For Tight Budgets: Xiaomi Monitor Light Bar

Only if $50 is your ceiling. The Xiaomi gets the basics right — asymmetric optics, auto-dim, USB-C powered — but the CRI and glare control are noticeably worse, and the build feels every bit of its price. Better than no light bar. Worse than either of the above.

Bottom Line

Buy the BenQ ScreenBar Halo 2 if you do color work or want the biased backlight and puck controller. Buy the Quntis Pro Plus if you want 90% of the experience for half the price. Skip the Xiaomi unless budget is the only consideration.
