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 (Jiangsu Keling Medical Appliances Co., Ltd.) 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.

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.

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.

Questions buyers ask

What is the KL04L-LED surgical light used for?

The Keling KL04L-LED is a LED surgical light for operating theatre illumination. It delivers 80,000 lux through a five-hole LED multi-reflector lamp head, providing bright, shadowless light for general and specialist surgical procedures in hospitals and procedure rooms.

How does the KL04L-LED differ from the halogen KL04L?

The KL04L-LED replaces the halogen bulbs with LED technology, increasing illumination from 60,000 to 80,000 lux, achieving instantaneous full brightness and providing more consistent output across its service life. Both share the same five-hole reflector head design, 24 V supply voltage and chassis options. The LED version does not include the battery-backup option available on the KL04L.I halogen variant.

Do the mobile variants have wheel locks?

Yes. Both mobile variants of the KL04L-LED series — KL04L.I (LED) and KL04L.III (LED) — are fitted with braking casters that lock securely to prevent the lamp from drifting during surgery. The brakes are engaged by foot pedal.

Can the KL04L-LED be ordered for hospital project supply or OEM?

Yes. Keling Medical supplies LED surgical lights to hospitals, operating theatre integrators and medical distributors worldwide through its Shanghai export center. Project quantities, OEM labelling and custom configurations are available; contact Keling Medical at https://www.kelingmed.com.
