Description

Engineered for professionals, ScreenBar Pro can adapt seamlessly to every screen—flat, curved, or ultra-wide. Its expansive, eye-safe illumination brings refined optical balance and lasting comfort to your workday, helping you stay efficient, confident, and focused from start to finish. ScreenBar Pro illuminates your workspace with 500 lx of evenly distributed light across a 33.5 × 19.7 in area—far beyond standard desk lamps. Clear, wide, and comfortable for lasting focus. Refined through over one million optical simulations, ScreenBar Pro’s asymmetric optics prevent screen reflection and deliver true zero glare with wide, even light for lasting eye comfort. ScreenBar Pro’s precise 18° anti-glare angle and adjustable lamp head block direct light from your eyes. Enjoy personalized lighting and prevent glare, keeping illumination focused on your workspace. Certified by EU IEC TR 62471 and IEEE PAR 1789 standards, ScreenBar Pro ensures flicker-free and blue-light-safe illumination—providing eye protection and comfort for long hours of screen use. As the creator of the world’s first monitor light, BenQ’s ScreenBar provides leading innovation in eye-care lighting. We work with experts and universities to solve lighting needs and protect vision. ScreenBar Pro features an ultrasonic sensor that detects motion within 23.6 inches (60 cm) in front of the screen. Its conical detection range prevents unnecessary activation when you simply pass by. The light turns on instantly when you sit down; when you leave, it gently dims and powers off after five minutes of inactivity. Smart automation keeps your workspace effortless, energy-efficient, and always in sync with you. ScreenBar Pro features advanced ambient light sensors that automatically detect your environment’s brightness and makes adjustments in real time to maintain optimal illumination. Designed to meet the ANSI-recommended 500 lx, it keeps your workspace consistently bright, balanced, and easy on the eyes—no manual adjustments required. Whether in the day or night, you always get the right light for comfort, focus, and productivity. ScreenBar Pro offers 16 brightness levels and 8 color temperature settings ranging from 2,700K to 6,500K, allowing you to fine-tune illumination for any task or time of day. Research has shown that cool light around 6,500K enhances focus, while neutral tones around 4,000K provide comfort for prolonged work. Warm light from 2,700K to 3,000K helps you unwind when you’re reading and supports better rest afterwards—giving you lighting that adapts to every mood and need. Engineered with a patented clamp, ScreenBar Pro has achieved industry-leading compatibility—securely fitting thin, flat, curved, and ultra-wide monitors 0.17–2.56 " thick and 1000–1800R in curvature. The rubber-sawtooth clamp grips securely without excess force, ensuring stability while protecting your monitor surface. Textured pads provide a firm, screen-safe hold that stays steady on any setup. Every contour is precisely shaped to stay clear of built-in cameras, keeping your video calls unobstructed on any monitor. Webcams can be easily mounted above the light bar with an included accessory. Simple, secure, and ready instantly—no tools required. Design with MINIMAL Embodies a calm, refined, and minimalist style that balances simplicity and elegance. Certified for Reliability Has passed strict durability and temperature tests to ensure long-lasting and certified quality. Full-Spectrum LED Light Delivers sunlight-like illumination with high color accuracy for professional visual fidelity. Flexible Power Options Powered via USB-C or 15W adapter, delivering stable & reliable illumination for any workspace setup.
