How do you use an integrating sphere to detect the quality of LED lighting products?

An integrating sphere is frequently used to measure luminaire or light source for luminous flux, chromaticity coordinates, CCT, dominant wavelength, peak wavelength, etc. The traditional integrating sphere is the IS-*M, which LISUN has already stopped manufacturing in favor of the IS-*MA, which uses a molding method. It is your finest choice to take into consideration if your application calls for the measurement of a beam that is widely divergent.

Integrating Sphere & Spectroradiometer for Photometry?

Lumen is a unit of measurement for the total amount of visible light emitted by a light source. It is an important parameter in lighting design and evaluation, as it reflects the brightness and effectiveness of a lighting system. To accurately measure lumen output, a spectroradiometer system with an integrating sphere is commonly used. In this technical article, we will discuss how to test lumen by integrating sphere spectroradiometer system.
