Xiaomi Monitor Light Bar Review: Premium Desk Lighting on a Budget

When Xiaomi set out to create a monitor light bar, they had one target in their sights: the BenQ ScreenBar. For years, BenQ’s monitor light bar was the gold standard — great lighting, no screen glare, and a premium price tag of around 800-1000 yuan. Then Xiaomi released theirs at 169-199 yuan, and the category was never the same.

With over 10,000 reviews on JD.com, a 4.8★ average rating, and unanimous praise across platforms like SMZDM, Zhihu, and Bilibili, the Xiaomi Monitor Light Bar has earned its reputation as the ultimate BenQ alternative. We dug into the reviews to find out if it lives up to the hype.

What Chinese Users Are Saying

The Lighting Experience

The star feature of the Xiaomi light bar is its asymmetric optical design. Light is projected downward onto your desk, with virtually no spill onto the monitor screen. SMZDM and Zhihu reviewers consistently confirm that this works as advertised — your monitor stays glare-free while your workspace is well-lit.

One Zhihu reviewer compared it directly to a BenQ ScreenBar and noted: “In a blind test, I honestly couldn’t tell them apart for daily office use. The Xiaomi’s Ra90 vs BenQ’s Ra95 makes a difference if you’re doing color-critical work, but for reading, writing, and general desk lighting, it’s identical.”

Stepless Color Temperature

The 2700K to 6500K range covers warm reading light to cool task lighting. The wireless remote control makes switching between modes effortless, though it does require a coin cell battery (CR2032). JD.com reviewers appreciate the convenience but note that battery replacement is slightly fiddly.

Where It Falls Short

The most significant limitation is curved monitor compatibility. The clamp-style mount is designed for flat monitors and can slide off curved screens. This is mentioned repeatedly by SMZDM and Zhihu reviewers with curved monitors — Xiaomi specifically warns about this, but it’s still a frustrating limitation.

For ultra-wide monitors (34-inch and above), the light coverage may not span the full width of the screen. Standard 24-27 inch monitors are fine, but the light pattern has a defined edge that becomes visible on larger displays.

The Value Proposition

Across all platforms, the consensus is overwhelming: at 1/5 the price of a BenQ, the Xiaomi Monitor Light Bar delivers 90% of the experience. The fit and finish are excellent, the magnetic mounting is simple and secure, and the lighting quality is genuinely good enough for 95% of users.

Pros

• ✅ Asymmetric optical design delivers glare-free screen experience
• ✅ At 169-199 yuan, it’s roughly 1/5 the price of BenQ ScreenBar
• ✅ Magnetic mounting is simple, secure, and tool-free
• ✅ Stepless color temperature adjustment (2700K-6500K)
• ✅ Wireless remote control keeps the desktop clean
• ✅ Ra90 color rendering index — accurate color reproduction

Cons

• ❌ Clamp doesn’t work well with curved monitors (slides off)
• ❌ Light coverage is limited — not ideal for ultra-wide monitors (34”+)
• ❌ Remote control uses a CR2032 coin cell battery, inconvenient to replace
• ❌ Color rendering (Ra90) is lower than BenQ ScreenBar Halo (Ra95)
• ❌ Requires USB power — occupies one port on your monitor or computer

FAQ

Q: Is the Xiaomi monitor light bar as good as the BenQ ScreenBar? A: For 90% of users, yes. In a blind test for daily office use, most people can’t tell the difference. Color-critical professionals might notice the lower Ra90 (vs. BenQ’s Ra95), and the BenQ’s build quality is slightly better. But for the price difference (199 vs 899 yuan), the Xiaomi is the obvious choice for most.

Q: Will the Xiaomi light bar work with my curved monitor? A: Officially, no. The clamp design is optimized for flat monitors. Some curved monitor users report success with thicker (>20mm) curved screens, but the clamp may slip on thinner or more aggressive curves. SMZDM recommends avoiding if you have a curved monitor.

Q: Does the Xiaomi monitor light bar cause eye strain? A: The asymmetric design significantly reduces direct eye exposure to the light source. Combined with the adjustable color temperature and brightness, most users find it more comfortable than overhead or desk lamps. The flicker-free design (not officially rated but confirmed by multiple reviewers) helps reduce eye fatigue.

Q: How does the Xiaomi mount to the monitor? A: It uses a weighted magnetic clamp system. The clamp hooks over the top edge of the monitor, and the light bar attaches magnetically. No adhesive is needed. The system works with monitor bezels 1-32mm thick.

Verdict & Rating

The Xiaomi Monitor Light Bar is one of those rare products that genuinely delivers flagship features at a fraction of the price. If you have a flat monitor and want better desk lighting without the BenQ price tag, this is an easy purchase. Ultra-wide owners and curved monitor users should look elsewhere — or wait for the rumored Pro version with wider coverage.
