What is an appropriate lumen range for general interior lighting?

The choice of 100-200 lumens per square meter is considered appropriate for general interior lighting because this range typically provides a comfortable level of illumination for most activities that take place indoors, such as reading, working, and socializing.

General interior lighting aims to create an evenly distributed light that ensures spaces are well lit without causing glare or shadowy areas. The 100-200 lumens per square meter range strikes a balance between providing sufficient brightness for visibility while allowing for energy efficiency and comfort.

Using this lumen range helps enhance the usability and aesthetic quality of spaces, contributing to the overall ambiance. Additionally, rooms designated for various activities—such as offices, living rooms, or classrooms—can consistently benefit from this lumen level to support different tasks and user needs.

Higher lumen levels may be suitable for specific applications or tasks that require more illumination, but as a general guideline, the 100-200 range is widely recommended for versatile indoor environments.
