The UNICA 520 LED surgical light is engineered to deliver deep, stratified illumination that remains completely glare-free, providing surgeons with exceptional visual comfort throughout every stage of a procedure. Its optical performance begins with a precision-engineered diffusion screen featuring a calibrated surface-roughness index, which collimates and layers the light evenly across the surgical field. This controlled, uniform light distribution minimizes fatigue and enhances visibility, even during long or intricate operations.
At the core of its illumination system is RIMSA’s patented 2R Double Reflection technology, which maximizes the illuminated surface area to produce exceptional brightness, clarity, and shadow-free depth. By combining two layers of reflective optics, the UNICA 520 achieves illuminance levels up to 160,000 Lux while maintaining an entirely glare-free beam. The lamp uses only white LEDs and provides seven selectable color temperature settings, delivering clean, neutral lighting without color distortion or unwanted colored shadows. This ensures accurate tissue differentiation and consistent visual fidelity across a wide range of surgical procedures.
The luminaire is designed for precision maneuverability and intuitive use. Its slim reflector allows smooth positioning, and an advanced electronic control system activates a secondary group of LEDs, which are reflected through carefully engineered optical lenses to create two independently selectable light-field diameters. Optical-grade PMMA lenses and high-reflective mirrors maintain crisp, always-in-focus illumination, while the Endoled function offers soft ambient lighting for calmer, low-intensity environments during delicate surgical phases. The design incorporates additional lighting technologies such as 3D light distribution, compensation-area control, and RIMSA’s Always-in-Focus illumination system, ensuring consistent performance even in deep cavities or in situations where multiple team members create potential shadowing.
To support diverse operating room requirements, the UNICA 520 integrates a wide ecosystem of accessories, including double yokes for dual-light setups, HD and 4K wired or wireless video transmission systems, monitor support arms, wall-mounted control panels, battery groups, IR remote control, and complete integration systems for advanced OR connectivity. It is available in multiple configurations tailored to different installation needs, such as single or dual ceiling-mounted versions—with or without double yokes—as well as a highly mobile stand-mounted option.
The light is suitable for a broad range of surgical specialties, including cardiac, thoracic, abdominal, and general surgery, along with neurosurgery, maxillofacial surgery, proctology, urology, gynecology, and organ transplantation. Its adaptability, consistent beam quality, and precise optical engineering make it an ideal illumination system for both routine and highly specialized procedures.
With a 52-cm lamp head diameter, adjustable light-field sizes ranging from 170 to 380 mm, and a selectable color-temperature range of 3,800 K to 5,400 K, the UNICA 520 provides flexibility for different surgical needs. The LEDs deliver a lifespan of more than 60,000 hours, and the light intensity can be smoothly adjusted from 3% to 100%, offering a reliable, long-lasting, and highly controllable illumination solution for modern surgical environments.
In high-acuity cardiac surgery environments, an LED surgical light or operating theatre light plays a critical role in maintaining consistent visibility within deep cavities where anatomical structures require absolute chromatic neutrality. The absence of color distortion supports surgeons during procedures that depend on accurate differentiation of tissues and vessels, especially when operating within narrow or obstructed spaces.
During neurosurgical interventions, an operating room light ensures stable, shadow-free clarity across microscopes, navigation equipment, and surgical frames. Subtle shifts in intensity or color temperature can significantly affect perception of neural pathways, so a fully balanced, glare-free field helps maintain concentration and precision through long, delicate procedures.
In maxillofacial surgery and reconstructive work, an LED surgical light provides uniform field structure that supports exact visualization of soft tissue, bone surfaces, and fine suturing zones across different patient positions. Consistent wide-area brightness prevents shadow interference when multiple surgeons or instruments occupy the working space.
Abdominal and thoracic procedures benefit from an operating theatre light capable of sustaining deep field penetration and uniform spatial distribution while large retractors and surgical instruments create complex shadow profiles. Multi-level color temperature control enhances the clarity of organs and vascular detail within high-contrast environments.
General surgery rooms rely on an operating room light that maintains a calm, visually comfortable atmosphere during transitions between procedures. Surgeons and staff frequently adjust field dimensions and color tones to match each patient’s requirements, which supports workflow efficiency and helps maintain visual accuracy across varied case types.
In urology and gynecology, where procedures involve reflective, moist, or complex anatomical surfaces, an LED surgical light contributes to stable visual balance without excessive glare. This controlled output reduces strain during endoscopic and open procedures requiring frequent changes in viewing angles.
Transplant centers require an operating theatre light capable of sustaining long-duration performance without flicker or chromatic drift. Stable light quality is crucial when teams coordinate across multiple disciplines and maintain continuous visibility of critical structures throughout extended surgical timelines.
In trauma and emergency settings, an operating room light must adapt quickly to unpredictable case conditions while maintaining consistent brightness across multiple working zones. Uniform cross-field coverage supports rapid assessment, suturing, debridement, and stabilization without visual interruption.
Microvascular procedures and delicate tissue reconstructions rely heavily on an LED surgical light that maintains neutral-white output across all intensity levels. Surgeons must differentiate subtle variations in tissue color and perfusion, making precise chromatic accuracy essential to procedural outcomes.
In teaching hospitals and training centers, an operating theatre light supports large surgical teams, cameras, and observation equipment by supplying broad, uniform light coverage that minimizes shadowing from multiple observers. Clear, stable illumination ensures accurate visibility for both the primary surgeon and students learning intricate techniques.
