Light performance test

 Photometric test, measures a luminaire's light intensity distribution in space using a goniophotometer in a controlled darkroom. The test collects data on luminous intensity and flux in different directions to create a light distribution curve (or IES file) that shows how light is spread, helping to evaluate the fixture's quality, efficiency, and suitability for a specific application.
