Enhance visibility and eye comfort with the ScreenBar Halo LED Monitor Light from BenQ. The ScreenBar Halo provides front and rear-facing lights with three different operating modes to balance the contrast glare between the screen and its surroundings.

For your convenience, the lightbar is powered via 5V USB-A and a wireless controller is included.

Front & Rear Facing LED Lights    3 Light Modes    Battery Powered Wireless Controller    Real-Time Auto Dimming

The precise front light evenly illuminates the desk space in front of the screen for those who want to concentrate. Turn on the immersive back light and enjoy your relaxing moments with ease. The front-and-back light illuminate the full field of view, making it more comfortable during screen work.

The wireless controller increases placement flexibility with precise operation of brightness and color temperature adjustment, my favorites setting, three light mode switching, and auto dimming within one meter range. Industrial precision bearings give you a smoothing adjustment feeling; optical sensor counting makes operations more precise.

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. You can apply auto-dimming in all three light modes.

Stepless brightness and color temperature choices allow you to make adjustments based on your needs. All color temperatures are compliant with American National Standards Institute (ANSI). Enjoy warmer lights for relaxation and energy replenishment; or cooler lights for concentration and boosting efficiency.

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 its surroundings. With the oval lighting designed for narrow spaces in front of the screen, BenQ's monitor light bar guarantees a lighting coverage of approximately 25 x 16" 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.

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.

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. With BenQ's unique clamp design, ScreenBar Halo is able to be placed instantly and stably on the top of different types of monitors with suitable thickness and curvatures.

With the built-in non-flicker driver chip, the flicker measurement of BenQ ScreenBar Halo is far superior to the industry standard and has passed the IEEE PAR 1789 standard for LED luminaires, giving you the most stable and safe light source. Additionally, it conforms to EU IEC/TR 62778, IEC/EN 62471 blue light standards. The highest quality LED light source is selected to protect your eyes in all aspects.
