    • Range: Typically above 90.
    • Importance: Higher CRI values improve the accuracy of tissue color representation, essential for surgical precision.

  4. Diameter of Light Field:

    • Measurement: Centimeters (cm) or inches.
    • Range: Adjustable, typically between 20 to 50 cm.
    • Importance: Allows for customization of the illuminated area to match the surgical site, providing targeted lighting where needed.

  5. Shadow Dilution:

    • Feature: Ability to reduce shadows from staff and equipment.
    • Importance: Maintains consistent lighting across the operative field, enhancing visibility and reducing interruptions during surgery.

  6. Heat Emission:

    • Measurement: Temperature rise (°C).
    • Range: Minimal for LED, higher for halogen.
    • Importance: Lower heat emission enhances comfort for the surgical team and reduces the risk of tissue drying.

  7. Lifespan:

    • Measurement: Hours.
    • Range: LED lights typically offer 30,000 to 50,000 hours.
    • Importance: Longer lifespan reduces the need for frequent replacements and maintenance, ensuring consistent performance over time.
