A well-designed method always provides a good level of performance in lighting based on the application. Fewer lumens yield poor performance, but more lumens represent wasted energy. So, making lumen in correct performance is the task. Any building designs optimal capacity can be specified with an adequate calculation procedure. Lighting designers use the photometric data of proposed fixtures as a starting point. For the calculation procedure, they consider the project location, indoor or outdoor, as well as environmental conditions like temperature and dirt.

The purpose of lighting calculation is to reach a suitable illuminance level for the intended application. The concept of illuminance describes lighting delivered per unit of area, and it is typically measured in foot-candles (lumen per square foot) or lux (lumens per square meter).

Lighting calculation can be done manually with many equations. But this approach demands considerable man-hours and is very difficult for complicated building design. So, it is better to make use of a software to make every calculation simple and professional with a standard method.

This software is a very important software for many professionals, such as architects, electrical engineer, and interior designers. All should have a knowledge base that is suitable to complement lighting design.
