LISUN is an integrating sphere manufacture in China

The Chinese company LISUN is in the business of producing spectrometer integrating sphere systems as well as other lighting testing equipment. Testing of lighting goods, including LED lights, incandescent lights, and CFL lights, is performed using their integrating spheres, which are used for photometric and colorimetric analysis

The integrating sphere gathers the light from a source, takes an average of it, and then outputs a source of light that is consistent and diffuse for measuring purposes. A highly reflecting substance is used to cover the sphere, and this ensures that the vast majority of light that enters the sphere is reflected numerous times, resulting in a more consistent output. After that, the output is placed via a spectrometer or photometer so that different characteristics, such as luminous flux, color temperature, and color rendering index, may be determined.

Integrating spheres manufactured by LISUN are created with the goal of being used in a laboratory environment for the purposes of quality control and research. They are very precise and may be tailored to the unique requirements of each clients in order to fulfill those requirements.
