Have you experienced these issues while working in a dimly lit room?

Eye Strain and Discomfort

Prolonged screen time in low lighting with uneven illumination or direct lamp reflection forces constant pupil adjustments, leading to eye strain and discomfort.
Limited Adjustability

Most desk lamps have fixed settings that may not suit all your needs for different usage scenarios.
Space Constraints

Desk lamps take up valuable space and often fail to fully illuminate your entire workspace.

Ultra-Wide Front and Back Lighting

The backlight reduces contrast between screen brightness and the surrounding environment, while the front light delivers a consistent 500 lx over an 33.2 x 19.7” area, ensuring balanced illumination across your keyboard and workspace. ScreenBar Halo 2’s ultra-wide front and back lighting is designed to balance your entire field of vision, maintaining a light contrast ratio of less than 1:3, in line with ANSI recommendations.

Enhanced Backlight Coverage

The patented triple-curvature backlight design precisely controls light distribution, expanding ScreenBar Halo 2’s backlight coverage by 423% compared to the first generation.

① Upper Curvature

Reduces light directly above the screen to avoid harsh light concentration.
② Underneath Curvature

Connects the upper and lower light areas, creating a seamless light pattern behind the screen.
③ Side Curvature

Extends the light further, widening the illumination on both sides of the screen.

For Enhanced Eye Comfort

A significant contrast between screen brightness and ambient light can cause eye strain. ScreenBar Halo 2 helps balance the lighting environment and alleviate eye discomfort.

A Letter from BenQ Lighting Lab

Discover how ScreenBar Halo 2 was born

In 2017, BenQ introduced the world’s first monitor light bar to help monitor users reduce eye strain. By listening to user feedback and collaborating with research experts, BenQ continuously refines its products. Recognizing that working in dim environments can lead to discomfort from the stark contrast between screen brightness and darkness, we developed the ScreenBar Halo 2. This model features a triple-curvature backlight and exclusive asymmetric lighting technology to minimize glare and reflections, providing a balanced, comfortable lighting solution for low-light workspaces.

" I would say that it's a vital tool in my processing "

My favorite feature of this light is its evenness—no spots on the screen. Others who use it agree: once you have it, you can't imagine being without it.
- Apple Hardware Engineer

" A Handy Product for Home Office Setup "

I like the features because it doesn't cause any glare and provides decent illumination without taking up a lot of space on the desktop...It sits well on the top edge of the screen and seems to be a natural part of the screen.

Enjoy Comfortable Lighting in 3 Simple Steps

Adjustable Color Temperature and Brightness

Stepless brightness and color temperatures (2700K-6500K) allowing you to adjust based on different scenarios or moods.

Full-Spectrum LED Chip with Rf>96

With a color spectrum close to sunlight, deliver accurate color reproduction for superior performance.

Automatic Lights On as You Sit

With its ultrasonic sensor positioned 50 cm (19.7”) above the desktop, it detects at a distance of 60 ± 10 cm (23.6 ± 3.9”) in front of the screen. Its detection shape is conical, which helps prevent unnecessary activation of the light, such as when the user walks past the desk. Since the sensor uses motion detection to decide whether to keep the light on or turn it off, if users remain still (e.g., watching a video) or make subtle movements (e.g., typing without body movements), the light may detect no motion and turn off after 5 minutes.

*ScreenBar Halo 2 uses an ultrasonic sensor to auto-control the light by emitting high-frequency sound waves and detecting movement based on reflected signals. However, environmental interference like temperature changes from heating/cooling devices or vibrations from humidifiers may affect accuracy and cause activation.

Real-Time Auto Dimming

With just one click, ScreenBar Halo 2 provides the recommended working illuminance of 500 lx, reducing eye strain during extended use.
Flicker-Free & No Blue-Light Hazard

Passed EU IEEE PAR 1789 for flicker-free performance and certified with EU IEC TR 62471 approval for no blue light hazard.
