Your desk deserves light that doesn't flicker, glare, or die after a year.
Why Not Just Buy the Cheap One?
Clip-on monitor lights from TaoTronics or Vekkia use cheap LEDs that flicker (causing eye strain), have poor color rendering (CCT < 80), and their plastic clips break. The BenQ ScreenBar Halo uses asymmetrical optical design to illuminate your desk without screen glare, with 95+ CRI and a wireless controller for brightness/color temp.
The Buy-Once Math
A $30 clip-on light lasts maybe 18 months before flickering or falling apart. Over the same 5 years, that's $100 and constant annoyance. The ScreenBar Halo lasts as long as your monitor, adds genuine desk ergonomics, and works on any monitor thickness. Pay once, see clearly forever.
