Standard Focus Mode
Balanced field for the majority of open procedures with Constella C or D heads.
Operating Room Lights
Constella Series
The definitive OT light - engineered for the future, with C and D dome choice and SpectraSure™ colour fidelity.
The complex parameters of surgical lighting are merged as harmoniously as the constellation of planets and stars in the Galaxy.
Constella is specified by cavity and room layout: a compact C dome (520 mm) or a larger D dome (720 mm), on a mobile stand or a ceiling mount with one, two, or three heads.
Purpose-built
What Constella delivers
Depth into the cavity, readable colour, effortless positioning, and optional shadow sensing - Constella packages these as one coherent OT light system.
High depth of illumination
Powerful, uniform light that stays readable deep into the surgical cavity.
Effortless 360° manoeuvring
Lightweight suspension and spring balance for all-axis positioning.
Adjustable CCT and focus
Smart LED design with colour temperature from 3500 K to 5500 K and four focus modes.
Cool functioning
Energy-efficient LEDs minimise heat so the team stays comfortable through the case.
Compact, streamlined design
A modern aerodynamic shape reduces visual obstruction and supports airflow around the head.
True-to-life colour
SpectraSure™ colour accuracy and saturation for tissue differentiation across the spectrum.
Sterile handle control (optional)
Surgeon controls from the sterile handle during the procedure, keeping hygiene in the field.
Auto shadow management (optional)
Sensors adjust lighting to minimise shadows based on real-time detection.
System overview
Controls, focus modes, and colour temperature in one view
Multi-colour LEDs deliver variable colour temperature from 3500 K to 5500 K. Smart focus control covers Standard, Narrow, Deep Cavity, and Endo modes.
Optional touch control panel, sterilisable handle, detachable Full HD camera, and auto shadow sensors complete the field setup on C and D domes.
Ambient lighting
SeraLux™ for the room around the field
SeraLux™ is an integrated ambient calming light system for patient and user comfort around the sterile field.
Focus modes
Focus for the procedure in front of you
The field changes with the cavity. Four modes cover open work, small cavities, deep sites, and endoscopic ambient lighting.
Narrow Focus Mode
Tighter field for smaller cavities such as neuro or paediatric work.
Deep Cavity Focus Mode
Enhanced depth for procedures that need light further into the cavity.
Endo Focus Mode
Ambient lighting tuned for endoscopic and minimally invasive visualisation.
Colour fidelity
SpectraSure™ for tissue that stays readable
The Normal versus SpectraSure comparison shows how calibrated colour keeps tissue differentiation readable when surgical decisions depend on what the team can see.
Multi-colour LEDs provide variable colour temperature from 3500 K to 5500 K. CRI is 96, with an optional boost up to 99 when the list needs still finer tissue differentiation.
Controls
Operational interface and options
Constella C and D domes share the same optical platform. What changes is head size, depth performance, and how the team interfaces with the field.
Constella C vs D
C dome at 520 mm suits compact rooms and smaller cavities. D dome at 720 mm adds reach and depth for wider tables and larger fields.
Touch control panel
Optional touch panel for faster field adjustment, colour temperature changes, and focus mode selection at the point of use.
Four operational modes
Smart focus control on every head: Standard, Narrow, Deep Cavity, and Endo.
Detachable Full HD camera
Optional camera aligned with the light for documentation and teaching lists.
Mount systems
Flexible solutions for every operating room
Mobile, single, double, and triple dome systems cover teaching theatres and multi-specialty rooms. Open any SKU on the configurations page for full optical detail on C and D heads.
In detail
SeraLux™ integrated ambient lighting
SeraLux™ is an integrated ambient calming light system for patient and user comfort around the sterile field. Endo focus mode pairs with ambient output for minimally invasive lists.
Touch control panel (optional)
An optional touch control panel gives faster field adjustment, colour temperature changes, and focus mode selection at the point of use.
Detachable Full HD camera
An optional detachable Full HD camera aligns with the light head for teaching and documentation lists. 10X and 30X optical zoom options are available.
C and D dome ceiling systems
Specify Constella C (520 mm) or D (720 mm) heads on mobile, single, double, or triple dome ceiling systems when the theatre programme needs wider coverage or redundant illumination.
