Operation Theatre (OT) lights are vital for surgical safety and precision. They illuminate the surgical field without shadows, minimize heat emission, and provide adjustable intensity and color temperature. This catalog presents ten major categories of OT lights, with history, specifications, annotated diagrams, applications, compliance, maintenance, pricing tiers, and customization options.

Halogen OT Light

History: Halogen OT lights were widely adopted in the mid-20th century, providing bright illumination at a relatively low cost. Although gradually replaced by LED lights, they remain in use in many developing regions.

– Illumination: 40,000–120,000 Lux
– Halogen bulb source
– Color temperature: 3,500–4,000 K
– Heat emission: High
– Service life: 1,000–2,000 hours

LED OT Light

History: LED OT lights represent the modern standard. They consume less power, emit less heat, and offer a longer lifespan compared to halogen lights. Widely used in advanced operating theatres globally.

Short Specifications:
– Illumination: 60,000–160,000 Lux
– LED light source
– Color temperature: 4,000–5,500 K adjustable
– Heat emission: Minimal
– Service life: 40,000–50,000 hours

Mobile OT Light

History: Mobile OT lights were developed to bring flexibility to minor surgeries and emergency rooms. They can be moved between rooms and adjusted as needed.

Short Specifications:
– Illumination: 40,000–100,000 Lux
– Stand-mounted with casters
– Dome size: 300–500 mm
– Adjustable height and angle
– Power: AC mains or rechargeable battery

Ceiling-Mounted OT Light

History: Ceiling-mounted OT lights became a standard in modular operating theatres, ensuring stability and free floor space. They are widely used for both general and specialized surgeries.

Short Specifications:
– Illumination: 60,000–160,000 Lux
– Dome size: 400–700 mm
– Fixed the ceiling arm with rotation
– Integrated control panel
– Shadowless design

Wall-Mounted OT Light

History: Wall-mounted OT lights are space-saving alternatives used in smaller operating theatres or as secondary lights for procedures.

Short Specifications:
– Illumination: 30,000–80,000 Lux
– Compact dome size: 300–500 mm
– Fixed wall arm with angle adjustment
– Simple controls
– Lower cost

Shadowless OT Light

History: Shadowless OT lights were introduced to eliminate shadows caused by surgeons’ hands and instruments. They are now the standard for surgical lighting, improving precision.

Short Specifications:
– Illumination: 80,000–160,000 Lux
– Multi-reflector system
– Dome size: 500–700 mm
– Adjustable color temperature
– Advanced optics for shadow elimination

Endoscopy OT Light

History: Endoscopy OT lights evolved to provide low-intensity, specialized lighting with green/blue filters to enhance visibility on monitors during minimally invasive surgeries.

Short Specifications:
– Illumination: 10,000–50,000 Lux
– LED/halogen options
– Color filters: Green/blue
– Compact dome
– Low heat emission
