What is photometric testing?

Photometric Testing provides a comprehensive laboratory service for testing the amount, colour, quality and spatial distribution of light emitted from lamps, LEDs and luminaires.

Principle of Photometry

Analyses which have the tendency to absorb light, when exposed to a beam of incident light, will absorb some. This results in reflection of a light of lower intensity.
