The BenQ ScreenBar Halo 2 clips to the top of a monitor and throws an asymmetric beam forward onto the desk, so it lights the work surface without bouncing glare off the screen. AppleInsider scored it 5 out of 5 and XDA praised the coverage and the easy adjustments; HowToGeek was more measured at 7 out of 10 on value. It is expensive, and the rear backlight matters most in a dim room.
- — Asymmetric front beam rated above 1,000 lux with no reflections on the screen
- — Tri-zone rear backlight balances a bright screen against a dark wall
- — Wireless puck controller handles brightness and colour temperature from the desk
- — Premium price for a light bar next to a capable basic desk lamp
- — The backlight benefit is mostly noticeable in darker rooms
- — USB-powered, so it needs a free port or the included adapter
