80. When inspecting the combustion section of a gas turbine engine, what wattage light source should you use?

A 1000-watt light source is required to adequately illuminate the deep, confined combustion section and reveal defects such as cracks or distortion. Lower wattage options provide insufficient illumination, while higher wattages are unnecessary and may pose a risk if used improperly. Standard industry practice dictates the use of a 1000-watt light for this inspection.
