BenQ ScreenBar Halo

BenQ ScreenBar Halo — monitor-mounted LED bar with asymmetric optics (illuminates desk surface without screen glare), back-glow bias lighting LEDs for eye strain reduction, ambient light sensor for auto-dimming, wireless remote controller, USB-A or USB-C powered from monitor hub, CRI 95+ claimed, 2,700–6,500K. Available at major online retailers. The premium price is a 6x multiple over the Baseus i-wok for the core monitor-bar function; monitor-mount only — no desk stand included or sold separately; back-glow can be distracting and increase perceived brightness in already well-lit rooms; requires powered USB ports on your monitor, and if your monitor lacks them, a separate USB power adapter is needed.

The BenQ ScreenBar Halo is the most complete monitor light bar in the comparison, combining asymmetric optics that direct light onto the desk without glaring back off the screen, a back-glow LED strip that delivers bias lighting behind the monitor, and an ambient sensor that auto-dims to maintain a consistent surface lux. The wireless puck controller is the practical detail that elevates daily use — you adjust brightness and 2,700–6,500K color temperature without reaching behind the monitor. BenQ claims CRI 95+, which is the kind of rendering quality where document review and casual color-checking remain reliable. It is monitor-mount only with no desk stand option, draws USB power from your monitor's hub, and at its premium price it is roughly six times the price of the Baseus. For screen-forward work where eye strain is the priority, it remains the reference.
