Multi-Reflector (Hole-Type) Surgical Lights

KL05L Halogen Six-Hole Surgical Light

Q: What is the KL05L used for?

The Keling KL05L is a halogen cold-light surgical lamp for operating theatre illumination. It delivers 80,000 lux through a six-hole multi-reflector head with infrared-filtered cold-light bulbs, providing bright, shadowless, low-heat illumination for general and specialty surgical procedures.

Q: What is a cold light source and why does it matter for surgery?

A cold light source is a lamp design that filters out infrared (heat) radiation from the light beam using optical filtering. For the KL05L, this means that despite delivering 80,000 lux, the thermal load at the surgical site is controlled: patient head temperature rise is limited to ≤ 2°C under surgical operation conditions. This reduces patient discomfort and the risk of tissue desiccation during prolonged procedures.

Q: What is the illumination depth of the KL05L?

The KL05L has a rated illumination depth of ≥ 500 cm, meaning it can deliver effective light into body cavities at depth, supporting abdominal, thoracic, pelvic and other deep-cavity surgical procedures where the operative field is below the surface level.

Q: Can the KL05L be supplied to hospital projects and distributors internationally?

Yes. Keling Medical exports surgical lights to hospitals, operating theatre contractors and medical distributors worldwide through its Shanghai sales and export center. The KL05L is available in all three configurations for bulk supply; contact Keling Medical at https://www.keling-surgicallight.com/contact/ for project pricing.

The Keling KL05L is a halogen cold-light surgical lamp delivering 80,000 lux at 1 m through a six-hole multi-reflector lamp head with 24 V, 125 W cold-light bulbs and a color temperature of 4500 ± 500 K. It is manufactured by Keling Medical (Jiangsu Keling Medical Appliances Co., Ltd.) and is available in ceiling-mounted (KL05L), mobile floor-standing (KL05L.I) and mobile wall-arm (KL05L.III) configurations for operating theatres, procedure rooms and emergency surgical areas.

Overview

The KL05L halogen surgical light represents a step up from the five-hole KL04L, adding a sixth reflector hole to its lamp head for a larger light field and a higher rated output of 80,000 lux — equalling the output of the LED KL04L-LED. The cold-light source technology is central to the KL05L's design: a filtering system removes infrared radiation from the lamp output, delivering the intense illumination required for surgery while minimizing heat deposition on the patient and surgical team. Patient head temperature rise is controlled to ≤ 2°C under surgical operation conditions, and total irradiance is held to ≤ 600 W/m², meeting standard safety limits for operating theatre lighting.

The six-hole multi-reflector configuration distributes the output from all six lamp positions into a seamless, shadow-free field. When surgeon hands or instruments partially block the lamp, the unobstructed holes compensate, maintaining even coverage of the operative site. Illumination depth of ≥ 500 cm ensures adequate light penetration into deep body cavities such as abdominal, thoracic and pelvic operative fields.

Three installation options serve different clinical environments. The ceiling-mounted KL05L is suited to dedicated operating theatres with fixed arm installations. The KL05L.I on a wheeled mobile base with a stable platform is deployed in procedure rooms, emergency departments and theatres shared across multiple specialties. The KL05L.III wall-arm mobile variant provides an intermediate option. All three share the same six-hole lamp head, cold-light bulb specification and photometric performance.
