LISUN LED goniophotometers are designed according to IES standards

When it comes to measuring the photometric performance of LED light sources, the Illuminating Engineering Society (IES) has established a set of criteria that LED goniophotometers must adhere to in order to be considered compliant. The Illuminating Engineering Society (IES) publishes criteria that may be used to determine the angular distribution of luminous intensity and the color rendering qualities of LED lighting products. A device known as a goniophotometer is used for the purpose of determining the luminous intensity of a light source from a variety of vantage points. While doing so, it rotates the light source and measures the quantity of light that is emitted in each of the different directions. This information is used to produce a photometric distribution pattern, which offers a representation of the light output of a source across a broad range of angles. This pattern may be used to make calculations about how much light is emitted from different directions. In order to
