Which of the following is NOT a requirement for luminaires under Article 410?

The statement indicating that luminaires may only use incandescent bulbs is not accurate in the context of Article 410 because the Code allows for a variety of light sources beyond just incandescent. Article 410 sets forth requirements that cover all types of luminaires, regardless of the lighting technology, including incandescent, fluorescent, LED, and others.

Luminaires must have adequate mounting design to ensure safe and stable installation. They must also be listed and labeled, ensuring that they meet specific safety standards and can be verified by a recognized testing laboratory. Additionally, luminaires must be designed for their specific installation location to ensure compliance with environment and use, addressing factors such as humidity, temperature, and physical exposure. This flexibility in light sources helps support advancements in lighting technology and energy efficiency, aligning with contemporary practices in electrical installations.
