What is the most common light source used in laparoscopic procedures?

• A. 500W Halogen Lamp
• B. 200W LED Lamp
• C. 300W Xenon Lamp
• D. 100W Xenon Lamp

Answer: (C)

In laparoscopic surgery, illumination must be bright, broad-spectrum, and color-accurate so tissue structures are easy to distinguish through the camera. Xenon arc lamps provide very bright, white light with excellent color rendering, which helps differentiate tissues and vessels under magnification. A 300-watt xenon unit delivers sufficient intensity for lighting deep abdominal cavities without sacrificing image quality, making it the most commonly used setup. Halogen sources tend to run hotter and are less bright, while LEDs are cooler and efficient but have become more common in newer systems; historically, the xenon 300W setup has been the standard for reliable, high-quality visualization.
