Quntis PRO+
Quntis PRO+ (non-RGB)51 CM · ≥1200 LUX · Ra95

Fit ledger — need → measured evidence

LIGHTS THE WHOLE DESK
≥1200 lux from a 51 cm (20.1 in) bar — the brightest claim and joint-longest body here, where the 45 cm bars leave the corners of a wide desk dark.
COLOUR YOU CAN TRUST
Ra95 CRI across 3000-6500K — the difference from BenQ's Rf>96 is imperceptible outside professional colour-critical work, and no bar replaces monitor calibration.
FITS YOUR MONITOR
Weighted clip with front-and-rear double adjustment and a 45° rotation shaft takes 0.12-2.36 in (3-60 mm) bezels, flat or curved — the widest clamp band under $100.
NEVER REACH OVER
Ambient-light auto-dimming (double-click the remote), a wireless remote with stepless dimming, and a 2-hour auto-off so it is not still on in the morning.
UNDER $80
$69.99, flat month-over-month — $39 below the original BenQ ScreenBar it out-specs on brightness, bar length and clamp range.
FLICKER ON THE RECORD
No IEEE PAR 1789 citation. Quntis publishes IEC/TR 62778 and IEC/EN 62471 RG0 blue-light conformity on its RGB Pro+, but 'flicker-free' here is a marketing claim, not a cited test result.

  The catch — co-equal billing, always

Its flicker performance is undocumented. Blue-light-hazard RG0 claims have commoditised across every tier, but BenQ is the only brand on this page that also cites IEEE PAR 1789 for flicker. Quntis does not. If you are flicker-sensitive, that missing test — plus BenQ's build feel — is exactly what the extra $69 buys.

Dealbreaker? Runner-up №1 publishes flicker testing, $69 over this cap ↓

  Every product has a catch. Verdicts that hide it are how bad buys happen.

Don't buy this if…

  • you need a full desk lamp with adjustable arm, not a monitor-mounted barLED desk lamp verdict →
  • you need a directional task lamp that reaches beyond the monitor footprint — drafting, sewing, model-making, paperwork off to the sidedesk lamps architect dossier →
  • you want RGB ambient backlighting for gaming aesthetics, not task lighting
  • you have a laptop without an external monitor and need portable lighting

Wrong product for you is still a bad buy. These are the cases where we'd send you somewhere else.

Traps — this verdict avoids

Why the Quntis PRO+ is right for you

It avoids every trap below — and for just me, under $80, it is the pick because it delivers:

Lights the whole desk Colour you can trust Fits your monitor Never reach over Under $80
Trap 01

The clamp, not the curve

Bezel thickness is the #1 return in this category. The original BenQ ScreenBar clamps 1-3 cm (0.4-1.2 in) only, the Halo 2 spans 0.43-6 cm and the ScreenBar Pro 0.43-6.5 cm — and many 2026 ultrawides and curved flagships carry top bezels thicker than 3 cm. Measure yours front-to-back before ordering. Nothing on this page is specified for an iMac, an all-in-one, a panel with a raised centre spine on the back, or curvature tighter than 1000R.

Trap 02

Five bars are called ScreenBar

BenQ sells five confusable models spanning roughly $109 to $199 and the names do not signal price order: ScreenBar ($109), ScreenBar Pro ($139), ScreenBar Halo 2 ($199), plus the prior-generation ScreenBar Plus and the first-generation Halo. If the listing shows a wired desktop dial it is a Plus; if the backlight is a single zone it is a Halo 1, not a Halo 2. Match the exact model before you compare any price.

Trap 03

It dies when the monitor sleeps

Every bar here is USB-powered and none has a battery. Run it from the monitor's own USB port and it switches off whenever that monitor sleeps, because most consumer displays cut hub power in standby. Only the BenQ ScreenBar Pro ships its own 15 W mains adapter; everything else needs an always-on PC port or a powered hub. Check the connector too — Halo 2, ScreenBar Pro and Xiaomi are USB-C; the original ScreenBar, both Quntis bars and the Yeelight are USB-A.
