What is Photometry?

Photometry refers to the measurement of light perceived by the human eye. It quantifies parameters such as:

• Luminous flux (lumens) – total visible light output
• Luminous efficacy (lm/W) – efficiency of light conversion
• Luminous intensity (cd) – concentration of light in a direction
• Chromaticity and CCT (Correlated Color Temperature)
• CRI (Color Rendering Index)

In LED testing, photometry ensures that lighting products meet both energy efficiency and visual comfort requirements.
