# KL04L-LED LED Surgical Light — High-Output LED Operating Lamp with Braking Casters
Quick answer: The Keling KL04L-LED is a LED surgical light providing 80,000 lux at 1 m through a five-hole multi-reflector lamp head with LED bulbs, a color temperature of 4500 ± 500 K and a CRI of 85–100. It is manufactured by Keling Medical (Keling Medical) and is the LED variant of the KL04L series, available in mobile configurations (KL04L.I LED and KL04L.III LED) with braking casters for stable, lockable positioning in operating rooms.
Quick Facts
- The Keling KL04L-LED is a LED surgical light delivering 80,000 lux at 1 m, an increase of 33% over the halogen KL04L's 60,000 lux.
- The lamp uses LED bulbs in a five-hole multi-reflector lamp head; color temperature is 4500 ± 500 K; CRI is 100 ≥ Ra ≥ 85.
- Power supply is 220 V ± 10%, 50 Hz; input power is 180 VA; rated bulb voltage is 24 V; rated power of bulb is 100 W.
- Total irradiance is ≤600 W/m²; total irradiance value is <6 mW/m²lx.
- Mobile variants (KL04L.I LED and KL04L.III LED) are equipped with braking casters for stable, lockable positioning.
- The KL04L-LED is a direct LED-technology upgrade of the KL04L halogen series, sharing the same mounting footprint.
Overview
The KL04L-LED LED surgical light is the LED-technology evolution of Keling's established KL04L series, retaining the familiar five-hole multi-reflector lamp head while upgrading the light source to LED for a significant increase in output, color accuracy and operating efficiency. At 80,000 lux measured at 1 m, it delivers 33% more illumination than the halogen KL04L, with the same controlled irradiance profile (≤600 W/m²) and tight patient temperature-rise limit (≤2°C) required for extended surgical sessions.
LED technology eliminates the warm-up time and gradual lumen decay associated with halogen bulbs: the KL04L-LED reaches full brightness immediately and maintains consistent output across its service life, reducing the need for mid-procedure bulb monitoring. The five-hole reflector design continues to blend output from all LED positions into a smooth, shadow-minimizing field — critical in situations where surgical instruments and hands partially block individual reflector sections. A CRI of 85–100 supports accurate differentiation of tissue types, blood and anatomical structures during surgery.
The two mobile variants — KL04L.I (LED) on a wheeled mobile base and KL04L.III (LED) on an alternative mobile chassis — are both fitted with braking casters that lock the lamp firmly in position once placed, preventing accidental drift during a procedure. The same 24 V bulb voltage allows facilities already using the halogen KL04L to evaluate LED performance without changing their supply infrastructure.
Key Features
- 80,000 Lux LED Output — higher illumination than the halogen equivalent (60,000 lux), providing clearer, brighter surgical illumination.
- LED Bulbs (Notes: the bulb is LED) — instantaneous full brightness, consistent output over service life and reduced heat compared to halogen technology.
- Five-Hole Multi-Reflector Head — independent reflector bays create a smooth, shadowless light field even when partially obstructed.
- CRI 85–100 — color temperature 4500 ± 500 K with high color rendering for accurate tissue and anatomical color differentiation.
- Braking Casters — lockable casters on mobile variants secure the lamp in place during surgery, preventing unintended movement.
- Controlled Patient Heat Exposure — irradiance ≤600 W/m²; temperature rise on patient's head ≤2°C during surgical operation.
- Mobile and Lockable Design — KL04L.I (LED) and KL04L.III (LED) mobile variants suit operating rooms, procedure rooms and emergency departments.
- Standard 24V Supply Voltage — compatible with existing surgical light supply infrastructure, simplifying facility upgrades.

Applications
The KL04L-LED LED surgical light is suited for general operating theatres, orthopaedic and trauma surgery suites, gynaecological and obstetric theatres, laparoscopy support rooms, ENT procedure rooms and minor surgery centres. Mobile variants serve as primary lights in smaller procedure rooms and as backup or satellite lights in larger operating suites.
