BenQ ScreenBar Halo: research-based review for small desks
The ScreenBar Halo is most interesting for compact workspaces because it attaches to the monitor rather than occupying the desktop.
What BenQ publishes
BenQ lists Ra≥95, 800 lux at the center at 45 cm, a 63 × 40 cm area at 500 lux, USB power, and specific compatibility ranges for flat and curved displays.
Why that matters in a small room
The monitor becomes the mounting point, so the lamp does not compete with notebooks, speakers, chargers, or the mouse area.
What to check first
Monitor thickness and rear shape matter. A light bar is also less useful if the main task is reading or craft work far away from the monitor.
BenQ ScreenBar Halo
Best suited to: Small desks where freeing the entire lamp footprint is valuable.
Watch for: Monitor-mounted lighting costs more than a basic desk lamp and compatibility should be checked first.

Workroom Standard conclusion
Verdict: the format makes strong sense for monitor-centered small desks, but it is a specialized solution rather than a universal replacement for a movable task lamp.
