Comprehensive Operating Theatre (OT) Lights

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
