# KL04L Halogen Surgical Light — Mobile Multi-Reflector Operating Lamp with Optional Battery Backup
Quick answer: The Keling KL04L is a halogen surgical light providing 60,000 lux at 1 m through a multi-reflector five-hole lamp head, with a color temperature of 4500 ± 500 K, Ra ≥ 85 color rendering and a 24 V, 100 W bulb. It is manufactured by Keling Medical (Keling Medical) and is available in ceiling-mounted, mobile floor-standing (KL04L.I and KL04L.III) configurations; the KL04L.I variant with battery backup is designed for power-outage scenarios.
Quick Facts
- The Keling KL04L is a halogen surgical light designed for surgical illumination in operating theatres and procedure rooms.
- Illumination at 1 m is 60,000 lux; optional color temperature is 4500 ± 500 K; color rendering index is 100 ≥ Ra ≥ 85.
- The lamp head uses a multi-reflector five-hole design with 24 V, 100 W rated bulbs.
- Power supply is 220 V ± 10%, 50 Hz; input power is 180 VA; total irradiance is ≤600 W/m².
- Mobile variants (KL04L.I and KL04L.III) are equipped with locking casters; KL04L.I with battery is suited for outage scenarios.
- Temperature rise on the patient's head under surgical operation is ≤ 2°C; service-range temperature rise is ≤ 10°C.
Overview
The KL04L halogen surgical light delivers a proven five-hole multi-reflector design that creates a broad, even pool of shadowless illumination at 60,000 lux — enough to serve a wide range of general and specialist surgical procedures without supplementary lighting. The multi-reflector optics blend light from all five lamp positions into a single smooth field that minimizes shadows even when the surgeon's hands and instruments obstruct individual lamp holes, maintaining consistent visibility throughout the procedure.
Three mounting configurations cover the spectrum of operating room setups. The ceiling-mounted KL04L is installed on a fixed arm bracket for permanent OR installation. The mobile KL04L.I on a wheeled base with locking casters can be repositioned between operating rooms or used in procedure rooms and emergency departments where a ceiling installation is impractical. The KL04L.I with integrated battery backup is the standby variant: it operates from mains power normally but switches to battery automatically on power loss, ensuring uninterrupted illumination during critical surgical moments. The KL04L.III provides an alternative mobile chassis design also with locking casters.
The 24 V, 100 W bulb is a widely used industry standard, simplifying procurement and on-site replacement. Total irradiance is controlled to ≤ 600 W/m² and patient head temperature rise is limited to ≤ 2°C under surgical operation conditions, meeting standard safety parameters for surgical lighting.
Key Features
- 60,000 Lux Surgical Illumination — high-intensity multi-reflector output for clear, consistent light across the operative field.
- Five-Hole Multi-Reflector Lamp Head — independent reflector bays combine to eliminate shadows even when partially obstructed during surgery.
- Optional Battery Backup (KL04L.I) — integrated battery allows continuous operation during power interruptions, critical for ongoing surgical procedures.
- Locking Casters (Mobile Variants) — KL04L.I and KL04L.III are equipped with locking casters for stable positioning and easy relocation.
- Ra ≥ 85 Color Rendering — color temperature 4500 ± 500 K and CRI ≥ 85 provide natural-white light for accurate tissue identification.
- Controlled Patient Heat Exposure — total irradiance ≤600 W/m²; patient head temperature rise under surgical operation ≤2°C.
- Standard 24V Bulb — widely available 24 V, 100 W replacement bulbs keep maintenance cost and complexity low.
- Three Mounting Options — ceiling-mounted (KL04L), mobile I (KL04L.I with battery option) and mobile III (KL04L.III) to suit any surgical environment.

Applications
The KL04L halogen surgical light is used for surgical illumination in general operating theatres, orthopaedic and trauma surgery suites, obstetric and gynaecological theatres, minor and intermediate procedure rooms, and emergency surgical areas. The battery-backed KL04L.I is particularly valued in facilities with unreliable power supply or as a mandated backup light in primary operating suites.
