Features

• LED cold-light technology: advanced LED cold-light source with no UV/IR emission; surgical-area temperature rise ≤1 °C; rated LED life ≥80,000 hours; energy-efficient.
• Intelligent optical adjustment: multi-level adjustable color temperature (3000 K–6700 K) and high CRI for accurate tissue contrast; uniform light column to reduce visual fatigue and ensure deep-cavity illumination.
• Precision control system: LCD touch interface with one-touch endoscopic mode; preset memory for customized parameters; independent multi-channel control for continuity in case of single-LED failure.
• Sterile-optimized design: seamless aerodynamic housing with aluminum-alloy heat dissipation; silicone sealing and dustproof construction compliant with laminar-flow cleaning; smooth surfaces for easy disinfection.
• Articulated suspension system: dual-curved arms with multi-joint linkage, 340° horizontal rotation and 90° vertical range; tested durability of 50,000 cycles for multi-angle positioning.
• Autoclavable focus handle: removable high-temperature resistant handle (autoclave ≤160 °C) for intraoperative sterilization and continuous focus adjustment.
• Premium components and safety: MEAN WELL power supplies; antibacterial and flame-retardant coating (EU RoHS compliant).
• Modular configurations: ceiling, floor or wall mounting; single- or double-head options; optional shadow-management, HD camera systems and 360° balance arms.
