The Merivaara Q-Flow LED surgical light brings together intelligent airflow engineering, advanced optical performance, and intuitive lighting control to support safe, efficient, and ergonomic work across a wide range of surgical applications. Its design is optimized specifically for the ventilation demands of modern operating rooms, where uncontrolled airflow can increase particle concentration and elevate the risk of hospital-associated infections. Traditional surgical lights often disrupt laminar airflow, causing air to rise and spread contaminants into the surgical field. In contrast, the Q-Flow’s aerodynamically engineered light head guides air smoothly around the luminaire, achieving an exceptionally low turbulence intensity of just 15.9 percent—far below the medical standard threshold of 37.5 percent. By minimizing turbulence, the Q-Flow helps maintain clean air over the operating area, reducing smoke and gas accumulation, improving visibility, and supporting a safer environment for both patients and staff.
At the core of the Q-Flow system is a shadowless optical platform that delivers bright, consistent, and high-fidelity illumination. The light provides a maximum output of 160,000 lux at one meter and a deep column of illumination reaching up to 1,800 mm at 20 percent, ensuring visibility into narrow cavities and complex surgical sites. Its color rendering performance is exceptional: the general color rendering index reaches Ra 98, with a market-leading R9 red rendering value of 98 for accurate visualization of blood and vascular structures, and an R13 “skin color” rendering value of 98, which is particularly important in plastic surgery and procedures requiring precise evaluation of skin tones. Surgeons also benefit from adjustable light field diameters ranging from 200 to 370 mm and variable color temperatures of 3700 K, 4400 K, and 5100 K. For environments requiring low-glare visualization of monitors, the Q-Flow integrates green ambilite to support comfortable reading of medical imaging.
Dynamic Obstacle Compensation (DOC™) enhances the optical performance by continuously adjusting light output when instruments or personnel temporarily block the beam. When an obstruction appears, the system increases intensity from the remaining LEDs to maintain uniform, shadow-free illumination. This reduces the need for surgical staff to reposition the light; traditional surgical lights require adjustment every 7.5 minutes on average, whereas DOC™ significantly decreases these interruptions, improving workflow, ergonomics, and overall productivity in the operating room.
Lighting control is a defining strength of the Q-Flow system. The primary touch panel interface offers clear, simplified control of brightness, field size, and color temperature, while integrated camera functions appear on the same screen without requiring additional equipment. The interface’s consistency extends across other Merivaara systems—including Merimote™ and the OpenOR™ integration platform—allowing staff to switch seamlessly between control stations. Surgeons working within the sterile field benefit from Merivaara’s patented Intuitive Sterile Surgeon Control (Intueri™), a hands-on adjustment method that enables immediate control of dimming and light field diameter without breaking concentration or looking away from the patient. When the sterile handle is grasped, the control interface activates automatically around the handle area, creating a natural, ergonomic method of adjusting lighting mid-procedure. The handle is available in both sterilizable and disposable forms to support various infection-control protocols.
The Q-Flow also offers sophisticated imaging capabilities through its integrated in-light camera. Fully enclosed behind the luminaire’s protective cover glass, the camera maintains a clear peripheral field for the surgeon and avoids cluttering the operating space. Its central mounting ensures that the camera always aligns with the illuminated field, even as the luminaire moves. Wireless 4K transmission supports real-time video streaming, enabling remote observation for consulting, teaching, or documentation. Camera controls are incorporated directly into the same user interface used for the light, eliminating the need for external consoles. Compatibility with Merimote™ and OpenOR™ provides additional flexibility for non-sterile staff to control lighting and imaging functions from outside the sterile zone.
Merimote™ itself expands lighting control beyond the immediate surgical field, offering a multifunctional wireless remote interface for Q-Flow luminaires, integrated cameras, and Merivaara operating tables. Its intuitive touchscreen mirrors the Q-Flow’s user interface, making it easy for staff to adjust lighting and camera functions from elsewhere in the room without interrupting the workflow of the surgical team. No preinstallation is required, allowing rapid deployment and flexible use across changing OR environments.
Across all these capabilities, the Q-Flow is built for functionality and simplicity. Its smooth, easy-to-clean surfaces uphold strict hygiene standards, while its lightweight construction supports effortless positioning. The system’s Fluent concept underscores usability, combining excellent optical performance, compatibility with OpenOR™ and Merimote™, and ergonomic lighting adjustments to support a wide range of surgical specialties. With flexible viewing options, green ambilite for monitor-based procedures, and sophisticated DOC™ and Intueri™ technologies enhancing comfort and control, the Q-Flow LED surgical light delivers a comprehensive solution for maximizing safety, visibility, and workflow efficiency in today’s operating rooms.
Designed and manufactured in Finland and recognized with international awards, the Q-Flow LED surgical light stands as a preferred choice for surgical teams seeking reliable optical quality, intelligent airflow integration, intuitive control options, and a clean, unobstructed environment suitable for every type of major and minor surgical application.
