Which statement about the installation of luminaires in clothes closets is accurate?

The statement indicating that recessed luminaires with enclosed light sources are permitted with proper clearance is accurate because the National Electrical Code (NEC) specifies clearances for lighting fixtures installed in clothes closets. The regulations are in place to prevent the risk of fire hazards caused by the heat generated from light sources being too close to combustible materials, which are commonly found in closets.

Recessed luminaires that are designed with enclosed or fully enclosed light sources can be safely installed in closets, provided they adhere to the NEC-defined clearance requirements from storage materials. This ensures that any heat dissipation from the luminaire does not ignite clothing, fabric, or other materials that may be stored nearby.

Understanding the specifics of these requirements is crucial for safe installations, which is why this option correctly reflects NEC regulations regarding closet luminaires. Other types of luminaires or configurations might not meet these safety criteria, reinforcing why this answer is aligned with best practices outlined in the code.
