What do "wet-niche" luminaries refer to in the context of pool lighting?

"Wet-niche" luminaries are specifically designed for underwater installation in swimming pools, ensuring that they meet the stringent safety standards set by the National Electrical Code (NEC). These fixtures are constructed to be moisture-resistant and safe for use in locations where they will be submerged in water.

The design of wet-niche luminaires focuses on preventing electrical shock hazards and ensuring that the electrical components are housed in protective enclosures that can withstand prolonged exposure to water. This is critical in maintaining both the functionality of the lighting and the safety of individuals using the pool.

Understanding the standards set forth in the NEC for wet-niche luminaires is essential for compliance and safety in a pool environment. This distinction is important because not all light fixtures can be installed underwater, and those that can must adhere to specific electrical requirements to mitigate risks such as electric shock.

Other options may address fixtures with other functionalities or applications, but they do not encapsulate the specific safety and design parameters needed for "wet-niche" lighting.
