Keling Medical has manufactured surgical lighting equipment since 1996 from its ISO 13485-certified production facility.
Quick Facts
- The Keling KL-LED-MD78 delivers a peak illuminance of 160,000 lux at 1 m distance under standard mode.
- In endoscopy (Endo) mode, the Keling KL-LED-MD78 provides 15,000 lux at 1 m for minimally invasive procedures.
- The KL-LED-MD78 features 84 imported LED modules with an average rated life of 50,000 hours.
- Color temperature on the KL-LED-MD78 is continuously adjustable from 3,000 K to 6,700 K via intelligent touchscreen.
- The red color rendering index R9 of the KL-LED-MD78 is ≥97, supporting accurate tissue color discrimination during surgery.
- The KL-LED-MD78 operates on universal power supply (110–240 V, 50/60 Hz) at 150 W input, suitable for global hospital use.
Overview
The Keling KL-LED-MD78 is a floor-standing, mobile single-dome LED shadowless operating lamp designed for surgical theatres, procedure rooms, and examination areas where a ceiling-mounted installation is unavailable or impractical. Mounted on a sturdy mobile base with lockable castors, the KL-LED-MD78 can be repositioned quickly between operating rooms or used as a supplementary light source alongside a fixed ceiling lamp, maximizing flexibility for multi-specialty facilities.
The lamp head uses 84 imported LED modules arranged to produce a uniform, shadow-free illumination field with a D10 light field diameter of 220 ± 40 mm and a depth of illumination (L1+L2) of 150 cm, meeting the demanding requirements of deep-cavity procedures. The heat-to-light ratio is kept at ≤3.2 mW/m²lx through nano-coated heat sinks, reducing thermal radiation on the sterile field and patient. Automatic illumination compensation maintains consistent lux output as individual LED modules age over time.
Keling Medical designed the KL-LED-MD78 with ergonomics and infection control in mind. The titanium alloy balance arm is seamlessly formed without welding to eliminate corrosion points, and the imported spring arm allows effortless height and angle adjustment. The intelligent touchscreen panel gives scrub staff intuitive control over brightness, color temperature, and operating modes — including an endoscopy auxiliary mode and dedicated minimally invasive lighting with R9 enhancement — without needing to touch the lamp head. A double-dome variant, the KL-LED-MD78D, is also available for facilities requiring higher total lux output over a wider combined field.
Key Features
- Imported LED cold light source — 84-module LED array produces 160,000 lux at 1 m with minimal infrared emission, keeping the operative field cool.
- Nano-coated heat sink — Advanced nano coating maximizes heat dissipation surface area, protecting LED longevity and maintaining low heat-to-light ratio ≤3.2 mW/m²lx.
- Intelligent touchscreen control — Panel allows stepless brightness adjustment, color temperature selection (3,000–6,700 K), and mode switching without repositioning.
- Adjustable color temperature (3,000–6,700 K) — Warm to cool white range suits general surgery, ENT, dermatology, and dental procedures with a single fixture.
- R9 ≥97 red color rendering — Exceptional red-spectrum fidelity ensures accurate differentiation of blood, tissue layers, and anatomical structures during open and minimally invasive surgery.
- Endoscopy auxiliary lighting mode — Dedicated Endo mode reduces illuminance to 15,000 lux for comfortable integration with endoscopic camera systems.
- Titanium alloy balance arm, no welding — Single-piece titanium alloy construction eliminates weld joints, preventing corrosion and structural fatigue in high-humidity OR environments.
- Imported spring arm — Precision-balanced spring arm allows the lamp head to be lifted, lowered, and repositioned with light finger pressure, holding position without drift.
- Automatic illumination compensation — Electronics continuously monitor and compensate LED output to maintain prescribed lux levels throughout the lamp's service life.
- Mobile floor stand with castors — Locking castors allow safe repositioning; the mobile base requires no ceiling infrastructure, suitable for retrofit installations.
