Photometry Training Course Brochure


Photometric Testing helps you to understand the basic concepts of light, LED and solid state lighting specifications. Our regular 2-day training course in photometry, Colorimetry and light measurement will help you to understand LED and lighting specifications and avoid common misconceptions that come to one’s mind while operating/testing these devices. We will show you how to correctly measure and express the performance of your lighting products and the training will benefit technical and marketing staff alike.

Training Insights:

Lighting is an exciting and rapidly developing area -LEDs and solid-state lighting promise not only energy efficiency but also designs. Yes!! LED specifications are often mistrusted and sometimes misleading too.

Developed in partnership with measurement equipment specialists Eurotech Assessment and Certification Services Pvt. Ltd. training course in Photometry, Colorimetry AND Light measurement through Gonio-photometer and integrating sphere help you to understand LED and lighting specifications, to separate the reality from fiction in LED specifications and show you how to measure and express the output of various lighting products and ways to interpret its results.

Our Training presents what is often thought as highly complex technical subjects in an easily understood way and combines a review of the theory of light and color measurement with practical, hands-on experience with the latest photometry equipment. Our state-of-the-art training lab contains integrating sphere, LED Power driver tester, Test Panel, Vitric, HV Tester, ECR, Gonio-photometers, Spectro-radiometer and many more.

Practical exercises included in the Photometry Training involve measuring the luminous flux-color temperature and color rendering of an LED fitting, a demonstration of the inverse squared law, and measurement through integrating sphere for the creation of data file.
