How are "luminaries" typically classified?

Luminaries are typically classified by their light source, which provides clarity regarding their functioning and use in various applications. Classifying luminaries by incandescent and electric discharge distinguishes between traditional light sources like incandescent bulbs and newer technologies such as fluorescent and LED lighting. This classification system is crucial for understanding the performance characteristics, energy efficiency, and applications of different types of lights.

In this context, the classification helps professionals choose the appropriate luminary for a specific task, optimizing lighting quality and energy use. Understanding the operational differences between these types of light sources enables linemen and electricians to make informed decisions when designing lighting systems in residential, commercial, or industrial settings.
