What does a luminaire enclosure's moisture rating indicate?

The moisture rating of a luminaire enclosure is a critical factor in determining the fixture's performance and safety in various environments. A luminaire's moisture rating specifically indicates its resistance to water ingress, which is essential in evaluating its suitability for locations that may be exposed to moisture or wet conditions.

A luminaire with a higher moisture rating typically means it has been tested to prevent water from entering, which is crucial for maintaining electrical safety and functionality, especially in areas like bathrooms, kitchens, or outdoors. This rating allows installers and electricians to make informed decisions about where to safely install the luminaire while ensuring compliance with the National Electrical Code (NEC).

Understanding the moisture rating helps prevent potential hazards related to electrical shock or damage to the fixture, which supports the overall reliability and longevity of the lighting installation in various environments.
