# KL05L Halogen Surgical Light — Six-Hole Cold Light Operating Lamp for Surgical Illumination
Quick answer: 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 (Keling Medical) 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.
Quick Facts
- The Keling KL05L is a halogen cold-light surgical lamp rated at 80,000 lux at 1 m for surgical illumination.
- The six-hole multi-reflector head uses 24 V, 125 W cold-light bulbs; color temperature is 4500 ± 500 K; CRI is 100 ≥ Ra ≥ 85.
- Power supply is 220 V ± 10%, 50 Hz; input power is 150 VA; total irradiance is ≤600 W/m²; total irradiance value is <6 mW/m²lx.
- Illumination depth is ≥ 500 cm; patient head temperature rise under surgical operation is ≤ 2°C.
- The KL05L cold-light source minimizes infrared heat emission, keeping the surgical site comfortable during extended procedures.
- Available in three configurations: KL05L (ceiling/arm mount), KL05L.I (mobile floor-standing) and KL05L.III (mobile wall-arm).
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.
Key Features
- 80,000 Lux Cold Light Output — high-intensity illumination from a six-hole multi-reflector head for clear, bright surgical field coverage.
- Cold Light Source Bulb — infrared-filtered 24 V, 125 W cold-light bulb minimizes heat radiation to the patient during surgery.
- Six-Hole Multi-Reflector Design — six independent reflector bays create a smooth, shadow-minimizing field even when partially blocked.
- Illumination Depth ≥500 cm — deep light penetration for abdominal, thoracic and pelvic surgical cavities.
- Ra ≥ 85 Color Rendering — natural white light at 4500 ± 500 K for accurate tissue and anatomical color differentiation.
- Controlled Patient Heat Exposure — total irradiance ≤600 W/m²; patient head temperature rise ≤2°C under surgical operation.
- Three Mounting Configurations — ceiling (KL05L), mobile floor (KL05L.I) and mobile wall-arm (KL05L.III) for flexible OR deployment.
- Suitable for Operating Room, Treatment Room, Outpatient and Emergency Use — broad application range confirmed by product imagery.

Applications
The KL05L halogen surgical light is used for surgical illumination in general operating theatres, orthopaedic, abdominal and thoracic surgery suites, gynaecological and obstetric theatres, outpatient procedure rooms, emergency surgical areas and treatment rooms. The cold-light source design also makes it appropriate for environments where patient comfort during prolonged illumination is a priority.
