Precision Light for the Late-Night Coder

Meet The World's First and Best ScreenBar Engineered For Programmers

In a dark room, your screen becomes the only light source. This creates Contrast Glare.

To focus on the near screen, the pupils should shrink. Yet in the dark, they must also dilate to let in more light. Caught between these opposite signals, your visual system is pulled in two directions, resulting in discomfort and rapid fatigue.

Your Eyes Are Forced into a Conflict

To focus on the near screen, the pupils should shrink. Yet in the dark, they must also dilate to let in more light. Caught between these opposite signals, your visual system is pulled in two directions, resulting in discomfort and rapid fatigue.

The only way to eliminate contrast glare is to minimize the extreme gap between your bright screen and the dark background. With even, gentle bias lighting, your eyes no longer struggle between two opposite signals.

Eliminate Contrast Glare: Balanced Backlight

The only way to eliminate contrast glare is to minimize the extreme gap between your bright screen and the dark background. With even, gentle bias lighting, your eyes no longer struggle between two opposite signals.

Precisely calculated light paths deliver wider, more even backlight for a smoother ambient glow.

Different from the last generation (ScreenBar Halo), ScreenBar Halo 2 delivering broader illumination that smooths the gap between screen and background.

BenQ patented tri-zone backlight precisely shapes light through up, down, and side curvatures. Its custom "inverted U-shaped" optical design spreads the backlight evenly across the wall No harsh bright spots, just a smooth and balanced glow.

To achieve the ultimate ambient balance, backlight alone isn’t enough. The front light dynamically adapts to ambient brightness, while the backlight smooths contrast behind the screen. After countless prototypes, our engineers perfected how both lights work in harmony —controlling contrast to meet the ANSI-recommended 1:3 and 3:1 ratios that reduce eye strain and maintain lasting visual comfort.

BenQ’s patented ASYM-Light™ Technology uses millions of optical simulations to refine a 24° adjustable lamp head, 8-section reflector, 12-angle lens, and 18° cut-off angle — creating a precise asymmetrical beam that lights your desk without hitting the screen. Every detail is engineered to reduce reflections and glare, keeping your eyes comfortable and focused.

Through over 100 prototype iterations, the clamp design adapts perfectly to every screen: from ultra-thin to curved, even monitors with a bulging back. Engineered for stability, it grips firmly without scratching your display, while keeping your desk free from bulky lamp bases.

Bulge on the Back of the Monitor​

it’s a night-and-day difference! If you've been struggling with cheaper screen bars like I was, I 100% recommend the Halo 2.

Especially like ScreenBar Halo 2's backlighting feature. It makes coding in the evening more fun again.

Perfect lighting for long programming sessions: no glare, no eye strain.

I often work at night without room lights, and Halo 2 made a huge difference — the backlight eases eye strain, and the front light brightens my desk without glare.
