How much clearance is required from a recessed light to combustible materials?

The requirement for clearance from recessed lights to combustible materials is crucial for ensuring fire safety in residential buildings. The correct clearance of 3 inches is established to prevent overheating of combustible materials that may come into contact with or be in close proximity to the light fixture. This space helps ensure that heat emitted from the light does not ignite materials such as wood, insulation, or other flammable substances that might be located nearby.

Maintaining this clearance helps to reduce the risk of fire hazards associated with recessed lighting. The specific distance is often derived from safety standards put forth in building codes, ensuring that installed lighting can operate safely without creating a fire risk from nearby materials.
