What must be considered when selecting luminaires for outdoor locations?

When selecting luminaires for outdoor locations, it is essential to choose fixtures that are specifically rated for outdoor use and designed to withstand various environmental conditions. Outdoor luminaires must be weather-resistant to endure elements such as rain, snow, humidity, and temperature fluctuations without sustaining damage or affecting performance. This means they often incorporate sealed enclosures, durable materials, and protective coatings to extend their lifespan and ensure safety.

Choosing a luminaire rated for outdoor use ensures compliance with safety and installation requirements outlined in the National Electrical Code (NEC). Indoor-rated fixtures lack the necessary protections against water ingress and temperature variations, which could lead to electrical hazards, fixture degradation, or inefficient lighting performance. This is why a specific rating for outdoor use is critical when selecting luminaires for external applications.
