Real-time Auto Dimming​
ScreenBar Halo is equipped with a built-in ambient sensor that promptly detects the ambient light and then supplements it automatically to 500 lux as recommended by the American National Standard for office lighting. ​
How bright is right? No need to guess anymore! ScreenBar Halo provides you with the right light in an easy way!​ You can apply auto-dimming in all three eye-caring light modes. ​

Multi-levels of Color Temperatures that suit your needs​ ​
Stepless brightness and color temperature choices for you to adjust based on your needs. ​
All color temperatures are compliant with American National Standards Institute (ANSI)
Warmer lights for relaxation and energy replenishment; cooler lights allows for concentration and boosting efficiency. ​

Lighting Coverage​
Ultra Wide Illuminance​

Traditional lamps are designed for paper reading. With the light source concentrated in the center of the desk, traditional lamps can not effectively balance the light between the screen and the surroundings. ​
With the oval lighting designed for narrow spaces in front of the screen, our monitor light bar guarantees a lighting coverage of 63cm*40cm at 500 lux, thereby illuminating clearly the documents in front of the screen. ​
ScreenBar Halo perfectly balances the contrast between the monitor and your surroundings that make your eyes more comfortable.

Unique Asymmetrical Optical Design​ ​
According to research, screen reflection is one of the causes of digital eye strain. ​
The inner reflective panel with a precise curvature allows the monitor light to deliver a wide and balanced illuminance, without causing any reflective glare on the screen.

The key to screen-reading illumination
Compared with the divergent light of other lamps, BenQ’s unique asymmetrical optical design frees you from screen reflection and direct glare shining into your eyes.

Patented Clamp
No base, more space! BenQ ScreenBar Series’ patented clamp design is inspired by the hanging instinct of animals. In contrast to the clip-on design, its counterweight mechanism allows the light bar to firmly stay on the monitor without damaging the monitor itself. ​
