Overview
The Keling KL-LED-DT6I is a double-dome ceiling-mounted LED shadowless operating lamp designed for hospitals and surgical centers requiring a high LED count, low-glare optical system, and reliable deep-cavity illumination. Each dome delivers 160,000 lux at 1 m, and the computer-programmed optical arrangement of the LED array maximizes shadowless rate across the light field. The light field diameter is adjustable from 10 cm to 30 cm to suit procedures ranging from focused microsurgery to wide-field abdominal access.
The KL-LED-DT6I employs optical PC (polycarbonate) lenses on each LED element, providing anti-glare performance that reduces eye strain for the surgical team during extended procedures. High thermal conductivity heat dissipation technology maintains a low temperature rise within the fixture, protecting both the LED components and limiting radiant heat to a heat-to-light ratio of ≤3.2 mW/m²lx at the operative site.
Depth illumination is a design priority of the KL-LED-DT6I: the condenser beam configuration can deliver focused light into deep surgical cavities, with the L1+L2 combined depth of illumination reaching 108 cm. An independently controlled Endo mode reduces output to 15,000 lux for minimally invasive procedures, and a dedicated R9 function mode (specialty mode for deep tissue rendering) supports challenging incision work requiring fine tissue-color discrimination.

Frequently asked questions
What is the Keling KL-LED-DT6I used for?
The Keling KL-LED-DT6I is a double-dome ceiling-mounted LED shadowless operating lamp used in hospital operating rooms to provide 160,000 lux of anti-glare, high color-rendering illumination. It is particularly suited to deep-cavity procedures via its condenser beam and 108 cm depth of illumination, and to minimally invasive surgery via its independently controlled Endo mode.
What makes the KL-LED-DT6I different from the KL-LED-D78?
The KL-LED-DT6I uses 108 LEDs (double dome) compared to 84 LEDs per dome in the KL-LED-D78, and incorporates optical PC lenses and a computer-programmed optical arrangement for a higher shadowless rate and anti-glare performance. The KL-LED-DT6I L1+L2 depth of illumination is 108 cm. Both models deliver 160,000 lux at 1 m and share Ra≥85, R9≥97 color rendering specifications.
Does the KL-LED-DT6I have a minimally invasive surgery mode?
Yes. The KL-LED-DT6I includes an independently controlled Endo mode that reduces output to 15,000 lux, applicable to all kinds of minimally invasive surgery. This eliminates camera wash-out in laparoscopic procedures without requiring manual reconfiguration of the fixture.
Is the KL-LED-DT6I available for OEM supply and international export?
Yes. The KL-LED-DT6I is manufactured by Jiangsu Keling Medical Appliances Co., Ltd. at its ISO 13485-certified facility and is available for export worldwide. The unit accepts 110–240 V, 50/60 Hz power supply. Keling Medical's Shanghai export center handles OEM, hospital, and distributor enquiries; contact information is available at our export team.
