Constella Series

Smart surgical lighting.

Practically Heatless.

with SeraLux™

Energy efficient LED Technology, paired with ambient blue light diodes on the border ensure that the surgeons under the dome do not feel the heat and strain that comes with a conventional OT Light, even when at full power (1,60,000lux)

High Depth of Illumination.

Prism’s proprietary illumination architecture blends unified optics, multi-spectral LED tuning, and intelligent thermal control to deliver stable, shadow-free, true-colour lighting with exceptional depth illumination and near-zero heat. Designed as an integrated ecosystem rather than a collection of components, it ensures unmatched clarity, comfort, and long-term reliability in every surgical environment.

Fully adjustable luminosity.

with SpectraSure™

Smart LED design with adjustable illumination (0-100%), color temperature and focus modes to ensure optimal lighting for all surgeries. Along with manual adjustments, Constella also comes with auto shadow management, using real-time sensor detection to compensate for darker areas and adjust for lighter tones.

Precise Lighting.

Quality over quantity.

Constella delivers over 98 CRI combined with 96+ GAI, producing light that is both natural and vivid, making it easier to identify tissues with confidence and precision. Constella improves visual performance and significantly reduces fatigue during long surgical procedures.

Focus Modes for Different Clinical Applications

Standard Focus Mode

Precise focus with a D50 of 150, and a D10 of 250. Can be used for the majority of surgical procedures.

Narrow Focus Mode

Special sharp focus mode with a D50 of 120 and a D10 of 200. Recommended for smaller operating cavity such as neuro or pediatric procedures.

Deep Cavity Focus Mode

Special focus mode designed to provide enhanced illumination in deep cavity procedures. Specially recommended for cardiac procedures.

Endo Focus Mode

Triple endo mode, warm, natural and cool to provide perfect ambient lighting for endoscopic procedures

Additional features

Compact, streamlined design.

The shape of the dome combines modern aesthetics, aerodynamics and visual comfort. The aluminium based dome is lightweight and an excellent conductor of heat, while the nimble design ensures that airflow is not obstructed and heat is dissipated.

Sterile Handle Control.

Allows the surgeon to control the light from a sterile handle during procedures, maintaining hygiene in the sterile field. The handle itself is detachable and sterilisable.

Effortlessly 360°.

Lightweight suspension and spring balance mechanism ensure effortless all-axis positioning. Perfected hydraulic technology also makes the dome feel almost weightless when maneuvering.
