Which type of lighting fixture is not covered specifically under Article 410?

Decorative lighting fixtures are not specifically covered under Article 410 of the National Electrical Code (NEC) because this article primarily addresses the installation requirements for various types of luminaires (lighting fixtures) that are categorized based on their function and construction.

Article 410 discusses fixtures such as recessed and track lighting, which are more functional and standardized in residential and commercial applications. These fixtures have specific installation guidelines and safety requirements due to their common use in providing general and task lighting.

In contrast, decorative lighting fixtures may vary significantly in design, style, and function, and they can often be installed in a variety of creative ways that do not conform to the stricter definitions or categories in Article 410. This lack of a standardized approach for decorative items means they do not fall under the same regulations as more typical lighting styles.

Understanding that decorative fixtures have their unique set of challenges and considerations, such as aesthetic appeal and mounting considerations, helps clarify why they are referenced differently than the other types of fixtures listed in the question.
