# KL-LED-STR78 Single-Dome LED Shadowless Operating Lamp — 160,000 Lux, Green Mode, Ra≥85

> **Quick answer:** The Keling KL-LED-STR78 is a single-dome ceiling-mounted LED shadowless operating lamp producing 160,000 lux at 1 m with a color rendering index Ra≥85 (R9≥97, R11≥97), manufactured by Keling Medical (Jiangsu Keling Medical Appliances Co., Ltd.) for hospitals, clinics, and medical distributors. The KL-LED-STR78 includes a dedicated green light mode for cardiac and neurosurgery and accepts universal 110–240 V power supply.

## Quick Facts

- The Keling KL-LED-STR78 delivers 160,000 lux illumination at 1 m working distance from a single dome.
- The KL-LED-STR78 includes an independently controlled Endo mode at 15,000 lux for minimally invasive procedures.
- The KL-LED-STR78 contains 87 LEDs per dome rated for 50,000 hours average service life.
- The KL-LED-STR78 features a green light mode (R11≥97) designed for cardiac surgery and neurosurgery requiring high color rendering of vascular tissue.
- The KL-LED-STR78 light field diameter is electrically adjustable from 10 cm to 30 cm with a 4-position memory function.
- Keling Medical (Jiangsu Keling Medical Appliances Co., Ltd.) manufactures the KL-LED-STR78 with a hollow lamp body designed for excellent laminar flow compatibility in sterile environments.

## Overview

The Keling KL-LED-STR78 is a single-dome ceiling-mounted LED shadowless operating lamp intended for surgical suites requiring high-fidelity color rendering and versatile illumination control. With a peak output of 160,000 lux at 1 m, it covers demanding general and specialty surgical procedures from a compact single-dome ceiling configuration. Light field diameter is electrically adjustable from 10 cm to 30 cm, and a 4-position memory function stores preferred brightness and field-size settings for quick recall between procedures or surgeons.

The KL-LED-STR78 incorporates automatic illumination compensation: a sensor port detects occlusion when the surgeon's head obstructs the light source, triggering automatic output increase from the unobstructed LED segments to maintain consistent operative brightness. A titanium-alloy independent step array delivers depth illumination suitable for deep-cavity procedures, eliminating glare from medical staff without compromising the illuminated surgical field.

A key differentiating feature of the KL-LED-STR78 is its green light mode, engineered for procedures such as cardiac surgery and neurosurgery that require a high green color rendering index (R11≥97). Combined with the standard Ra≥85 and R9≥97 specifications, this mode supports surgeons working with fine vascular structures where tissue-color discrimination is critical. The hollow lamp body design promotes smooth laminar airflow around the fixture, supporting clean-room and laminar-flow OR environments.

## Key Features

- **160,000 lux single-dome output** — High-intensity illumination at 1 m working distance suitable for complex, long-duration surgical procedures.
- **Automatic illumination compensation** — Sensor port detects head occlusion; untouched LED segments compensate automatically to ensure ideal operative brightness.
- **Green light mode (R11≥97)** — Dedicated mode for cardiac surgery and neurosurgery requiring precise color rendering of vascular and neural tissue.
- **Minimally invasive (Endo) mode** — Independently controlled illumination at 15,000 lux applicable to all minimally invasive surgery types.
- **Independent depth illumination** — Titanium-alloy independent step array provides depth illumination for deep-cavity procedures while eliminating glare for surrounding staff.
- **Electrically adjustable light field** — Light field diameter adjustable from 10 cm to 30 cm with 4-position memory function for rapid recall.
- **Adjustable color temperature** — Continuously adjustable from 3,000 K to 6,700 K to match tissue type and surgeon preference.
- **Hollow lamp body for laminar flow** — The hollow lamp body design follows smooth laminar surface principles, providing excellent laminar flow cleaning adaptability in sterile OR environments.
- **High color rendering index** — Ra≥85 (max Ra=100) and R9≥97 accurately represent original tissue color; RI index function benefits deep and difficult incisions.
