# KL09L / KL12L / KL1205L LED Surgical Light Series — Professional Ceiling LED Operating Lamps
Quick answer: The Keling KL09L, KL12L and KL1205L are a family of ceiling-mounted LED surgical lights covering five-hole (KL09L), nine-hole (KL12L) and twelve-hole (KL1205L) lamp head configurations, delivering 100,000 lux, 160,000 lux and up to 300,000 lux respectively. They are manufactured by Keling Medical (Keling Medical) for modern operating theatres and feature stepless illuminance adjustment, adjustable focus, convenient handle repositioning and a porous heat dissipation structure.
Quick Facts

- The Keling KL1205L is a twelve-hole ceiling LED surgical light with illumination starting at 300,000 lux (five-hole note: 900,000 lux for the twelve-hole) — see spec table below for model-by-model figures.
- All three models share Ra ≥ 85 color rendering, stepless illuminance adjustment, focus adjustment and a porous heat dissipation structure.
- Power supply for all models is 110–240 V AC, 50/60 Hz; rated bulb voltage is 24 V.
- The KL12L and KL1205L include a convenient lamp handle for easy repositioning during procedures; all models are ceiling-mounted.
Overview
The KL09L / KL12L / KL1205L LED surgical light series provides a scalable, ceiling-mounted LED illumination solution that matches lamp head size to the complexity and scale of the surgical procedure. The KL09L's compact five-LED round head suits smaller operating theatres and specialist procedure rooms where a moderate-footprint ceiling light is appropriate. The KL12L steps up to nine LED positions in a larger round head for general operating theatre use, and the KL1205L's twelve-LED configuration delivers maximum output for major surgical suites, cardiovascular theatres and neurosurgery rooms where the highest illumination levels are required.
All three models are built on a common design platform featuring stepless illuminance adjustment — allowing the surgeon to dial the light output between the minimum and maximum rated values without discrete steps — and a focus adjustment control that modifies the beam pattern to concentrate or spread the light field according to the depth and width of the operative site. This combination of continuous dimming and focus control enables precise adaptation to different surgical phases: wide-field orientation, close-focus tissue manipulation and illumination of deep cavities, all without interrupting the procedure.
A convenient handle on the lamp housing (shown as a standard feature on KL12L and KL1205L, and fitted to KL09L) allows the surgical team to reposition the lamp head safely while maintaining a sterile field. The porous heat dissipation structure integrated into the lamp housing manages LED thermal output, maintaining stable lamp performance across extended surgical sessions and contributing to long service life.
Key Features
- Three-Model Scalable Series — KL09L (five-hole), KL12L (nine-hole) and KL1205L (twelve-hole) provide matched output for different operating theatre scales.
- Stepless Illuminance Adjustment — continuous, smooth dimming from minimum to maximum rated output for fine-tuned adaptation to each surgical phase.
- Focus Adjustment — adjustable beam focus allows the surgeon to concentrate light on a small, deep area or spread it across a wide field without moving the lamp.
- Convenient Handle — ergonomic repositioning handle allows the surgical team to adjust the lamp position during procedures while maintaining aseptic technique.
- Porous Heat Dissipation Structure — integrated thermal management maintains stable LED performance and extends lamp service life across long procedures.
- High Illuminance Output — KL09L 100,000 lux, KL12L 160,000 lux, KL1205L rated higher; all delivering professional-grade surgical illumination.
- Stable Color Temperature — 4500 ± 500 K across all three models for consistent, reliable color rendering throughout the procedure.
- Ceiling-Mounted Installation — ceiling suspension arms with smooth movement and stable positioning for precise lamp placement.

Note: The catalog lists KL1205L illumination as "five-hole: 900,000 lux" which likely refers to combined dual-head specification. Contact Keling Medical for confirmed single-head lux values. Specifications are subject to change; dimensional tolerances may apply.
Applications
The KL09L / KL12L / KL1205L series is suited for ceiling-mounted surgical illumination in general operating theatres, orthopaedic and joint surgery suites, cardiovascular and thoracic theatres, neurosurgery rooms, ENT and maxillofacial suites and outpatient procedure rooms. The scalable three-model range allows hospital facilities managers to specify appropriate output levels for each operating room type within a single product family.
