What is the purpose of a photometric report?

The primary purpose of a photometric report is to provide data on light output and distribution characteristics. This report includes crucial information such as the luminous intensity, the angle of light distribution, and overall light output (measured in lumens) from a specific luminaire or lighting fixture. This information is essential for designers and engineers to ensure that lighting meets the required standards for various applications, whether it’s for general illumination, task lighting, or accent lighting. A photometric report helps in understanding how light will perform in a given space, thus aiding in effective lighting design and placement.

In contrast, assessing the cost of installation or evaluating energy consumption are not the primary focuses of a photometric report. Those assessments typically involve economic and energy analysis that looks at different aspects of the lighting system, but they do not provide the detailed output and distribution data that a photometric report encapsulates. Similarly, while the aesthetic appeal of lighting design is important, it falls outside the scope of what is measured in photometric data, which is more technical and focused on quantifiable lighting performance.
