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.

Frequently asked questions

What is the KL-LED-MDTR78 used for?

The Keling KL-LED-MDTR78 is a mobile double-dome LED shadowless operating lamp used to provide high-intensity, color-accurate, shadow-free illumination during open and minimally invasive surgical procedures. Its unique R9+R11 dual auxiliary mode and electrically adjustable focus make it especially suited for procedures requiring precise differentiation of red (vascular) and green (biliary, lymphatic) tissue structures. The KL-LED-MDTR78 is mounted on a mobile floor stand and does not require a ceiling installation.

What are the R9 and R11 modes on the KL-LED-MDTR78?

On the Keling KL-LED-MDTR78, R9 mode enhances the red color rendering index to ≥97 for improved differentiation of blood vessels, bleeding points, and muscle tissue. R11 mode enhances the green color rendering index to ≥97, improving contrast for bile ducts, lymph nodes, and connective tissue structures. Both modes are accessible via the intelligent touchscreen and can be toggled during a procedure without adjusting the lamp head position. Standard white illumination at adjustable color temperature (3,000–6,700 K) is also available.

How does the electrically adjustable focus work on the KL-LED-MDTR78?

The KL-LED-MDTR78 features a motorized focus adjustment system controlled via the touchscreen panel, allowing the surgical team to increase or decrease the illumination field diameter without physically touching or repositioning the lamp head. This is particularly important for maintaining sterility during delicate procedures. The focus range follows the D10 (220 ± 40 mm) and D50 (110 ± 35 mm) field parameters with smooth electronic control.
