Ceiling-mounted surgical light L9

LEDwith control panelshadowless

Overview
L9 Surgical Light provides stable, flicker-free illumination for surgical procedures with features to protect vision, reduce eye fatigue and maintain a shadow-free field.

Key features

• DC Dimming Technology: controls illuminance without high-frequency flicker to support safe vision and artifact-free surgical recording.
• Eyes-protection Mode: reduces contrast between the surgical site and surroundings to lower visual strain.
• Multi-color Endo Mode: up to six selectable endoscopic light colors to aid tissue differentiation and operator comfort.
• Intelligent Shadow Management: compensatory illumination maintains a continuous, shadow-free surgical field when parts of the panel are obstructed; blocked sections reduce output to limit local heat.
• Elliptical Spot: beam pattern suited for long or narrow incisions to reduce metal reflections and better match incision shapes.
• Adaptive Illumination – Auto Focus: three automatic modes detect distance and keep spot size and illumination consistent; optimal working range 75 cm to 125 cm from the wound.

Modes & Operation

• Three automatic modes including auto-focus to maintain constant spot size and illumination across the recommended working distance.
• Endoscopic mode with selectable multi-color output to reduce eye fatigue and support tissue visualization.

Benefits

• Flicker-free recording and reduced eye fatigue due to DC dimming.
• Reduced heat near the surgeon when portions of the panel are dimmed by obstruction.
• Improved tissue visualization and differentiation using selectable endo colors.
