    Solar Light Company Inc.

    Solar Light offers 3 ranges of Solar Simulator products that satisfy the wide range of applications and markets where these products are used. The first range is the small laboratory models, the 16S range. These are used by education and research facilities, maybe pilot plants to set up, to demonstrate and prove the use of a solar simulator to produce UV radiation for such effects as fade testing, degradation testing, as well as sunscreen protection testing and so on. Each 16S solar simulator can output several times the UV level of natural sunlight, which enables accelerated testing to be carried out, saving time. All models comply with the prevailing standards and protocols for the particular testing they are being used for. For example, in clinical studies with sunscreens, they comply with the ISO standards, FDA and COLIPA. For materials testing, they comply with relevant ASTM, ISO and MIL standards. The 16S Simulators are also available with a full Air Mass 1.5 spectral output, which closely follows the solar spectrum and complies with the ASTM standards for Class A spectral match. This enables controlled research for photovoltaic testing and solar panel research.
