Overview

Operating theatre (OT) surgical light engineered for precise, uniform illumination.
600 mm light head diameter delivering maximum central illumination of 160,000 lux at 1 m.
Adjustable correlated colour temperature (CCT) from 3500 K to 5500 K with SpectraSure™ high-fidelity colour rendering.
Four programmable focus modes: Standard, Narrow, Deep Cavity, and Endo.
Available in three control tiers: Standard (keypad-led), Pro (double C-arm and touch control), and Ultimate (adds four-sensor auto shadow management, sterile handle control and CRI boost).
LumiDepth™ optical design targeting 99.3% isometric luminance for uniform illumination deep into the cavity.
Energy-efficient LED design minimises heat at the surgical field; LED service life approx. 60,000 hours.
Modular options: single, double or triple dome ceiling systems; mobile mounting for temporary/shared rooms.
Optional accessories: detachable Full HD or 4K arm cameras, monitor arm (supports surgical displays up to 32" with up to 1800 mm reach), recording/backup and other integration accessories.

Key features

High depth of illumination and uniformity for readable tissue colour and depth.
Effortless 360° manoeuvring with lightweight suspension and spring balance (Pro/Ultimate use double C-arm for smoother movement).
Adjustable CCT and four focus modes for procedural flexibility (Standard, Narrow, Deep Cavity, Endo).
True-to-life colour fidelity via SpectraSure™; CRI 96 on standard tiers with an optional CRI boost to 99 on Celesta Ultimate.
Optional sterile handle control and auto shadow management (sensor-based) to keep the sterile field clear without manual adjustments.
Integrated ambient lighting for endoscopic and minimally invasive workflows without additional ceiling fixtures.

Focus modes

Standard Focus Mode — balanced field for the majority of open procedures with the Celesta 600 mm head.
Narrow Focus Mode — tighter field for smaller cavities (neurosurgery, paediatric work).
Deep Cavity Focus Mode — enhanced depth for illumination further into the surgical site.
Endo Focus Mode — ambient lighting tuned for endoscopic and minimally invasive visualisation.

Controls & configurations

Standard tier: keypad control for everyday surgical lists; touchscreen interface optional; standard arm suspension.
Pro tier: double C-arm suspension and touchscreen interface for smoother manoeuvring; sterile handle control optional; auto shadow management optional.
Ultimate tier: double C-arm, touchscreen interface, sterile handle control (yes), four-sensor auto shadow management (yes) and CRI boost to 99.
Multi-dome ceiling systems (single, double, triple) available for wider coverage or redundancy.
