Photometrics

Photometric is the science of the measurement of light. Watch the video and learn how a luminaire delivers its light at what angles and intensity.

The basics of Lighting optics

As we learn more about light what we really want to understand is optics that is the control of light. Watch the video and learn more about lighting optics, light reflection and refraction.

Lighting Terminology

During the video the most commonly used lighting metrics such as intensity, flux, Illuminance, exitance and luminance and their measurements are explained.
