Why is it important for recessed lights to be IC-rated?

Recessed lights that are IC-rated (Insulation Contact-rated) are specifically designed to be safely installed in insulated ceilings. These fixtures are constructed to prevent heat buildup when covered with insulation, which significantly reduces the risk of overheating. This feature is crucial because overheating can not only damage the light fixture itself but can also pose a fire hazard to the surrounding materials and structure of the building.

By using IC-rated fixtures, you ensure compliance with safety standards and create a secure environment for both the lighting system and the building's occupants. Additionally, IC-rated lights can be installed in areas where insulation is present without the need for additional clearance, offering flexibility in residential design and efficiency in energy use.
