- Automatic illumination compensation on the KL-LED-MDTR78 maintains consistent lux output throughout the lamp's 50,000-hour LED life.
- The KL-LED-MDTR78 uses 84 imported LEDs and a titanium alloy no-weld balance arm, with an imported spring arm for drift-free positioning.
- The KL-LED-MDTR78 operates on universal power supply (110–240 V, 50/60 Hz) at 150 W input, compatible with global hospital electrical systems.
Overview
The Keling KL-LED-MDTR78 is a floor-standing mobile double-dome LED shadowless operating lamp that combines premium lux output with advanced color rendering capabilities not found in standard surgical lights. It is the flagship mobile model in the Keling Medical TR-series, distinguished by its dual R9+R11 auxiliary illumination modes and electrically adjustable focus — features that address the needs of surgeons requiring precise, hands-free light field control and accurate color discrimination across multiple tissue types simultaneously.
The KL-LED-MDTR78 uses 84 imported LED modules arranged across twin domes to produce a uniform, shadow-free illumination field with a D10 diameter of 220 ± 40 mm and a depth of illumination (L1+L2) of 150 cm. The heat-to-light ratio is ≤3.2 mW/m²lx, maintained by nano-coated heat sinks that efficiently disperse thermal energy away from the patient and surgical team. Automatic illumination compensation circuitry continuously monitors LED output and compensates for any degradation, ensuring the specified lux level is maintained throughout the lamp's service life without manual recalibration.
The mobile floor stand with lockable castors allows the KL-LED-MDTR78 to be repositioned quickly between operating rooms or used as a high-output supplementary light source alongside ceiling-mounted fixtures. The intelligent touchscreen provides single-touch control of brightness, color temperature (3,000–6,700 K), focus size, and R9/R11 mode selection. The removable handle cover simplifies OR disinfection protocols, while the titanium alloy no-weld balance arm and imported spring arm provide stable, rust-free positioning at any angle. Both single-dome and double-dome mobile variants are available from Keling Medical.
Key Features
- R9 ≥97 red auxiliary illumination mode — Enhances red-spectrum rendering for superior differentiation of blood vessels, muscle layers, and bleeding points during surgery.
- R11 ≥97 green auxiliary illumination mode — Dedicated green-channel enhancement improves contrast of bile ducts, lymph nodes, and connective tissue structures.
- Electrically adjustable light focus size — Motorized focus adjustment allows the surgical team to resize the illumination field without touching the lamp head, maintaining sterility.
- Automatic illumination compensation — Electronics actively maintain prescribed lux output as LED modules age, eliminating brightness drift over the 50,000-hour life.
- Imported LED cold light source — 84-module LED array delivers 160,000 lux with low infrared emission to minimize thermal load on the sterile field.
- Nano-coated heat sink — Advanced nano coating maximizes heat dissipation efficiency, keeping the heat-to-light ratio at ≤3.2 mW/m²lx.
- Intelligent touchscreen control — Single-panel control of lux, color temperature, focus, and R9/R11 mode without sterility-compromising arm adjustment.
- Endoscopy surgery auxiliary lighting — Endo mode provides 15,000 lux at 1 m for seamless integration with endoscopic camera systems.
- Titanium alloy balance arm, no welding — Seamless titanium construction prevents corrosion and structural fatigue in high-humidity, high-disinfection OR environments.
- Imported spring arm, lift and flex — Precision spring mechanism allows effortless lamp head repositioning with stable hold at any angle.
- Removable handle cover — Detachable handle sheath facilitates cleaning and disinfection between surgical cases.
- Mobile floor stand with castors — Locking caster base requires no ceiling infrastructure, enabling flexible deployment across departments.
