What is the minimum clearance required for recessed fluorescent luminaires or recessed incandescent/LED luminaires with a completely enclosed light source?

The minimum clearance required for recessed fluorescent luminaires or recessed incandescent/LED luminaires with a completely enclosed light source is established at 6 inches. This clearance is crucial for safety and performance, as it helps prevent overheating and allows for proper air circulation around the fixtures.

Maintaining this distance reduces the risk of heat buildup, which can lead to premature failure of the luminaires or even fire hazards if neighboring materials are too close. The requirement ensures that there is adequate space for heat dissipation, allowing the light source to operate efficiently and safely over time.

This clearance is specifically highlighted in the NEC to promote proper installation practices within both commercial and residential applications. Adhering to these standards is essential for electricians and anyone involved in electrical installations to ensure compliance with code regulations and to foster safe operating environments.
