About Us

Solar Light Company, LLC has been providing research professionals with laboratory-grade solutions for the advancement of light sciences ever since we invented the world’s first Solar Simulator in 1967. The company is recognized worldwide as America’s premier manufacturer of Precision Light Sources, Light Measurement Instrumentation, UV Transmittance Analyzers, Meteorological Instrumentation, OEM Instrumentation, and over 135 different types of Sensors. We also provide a wide array of services, including accelerated UV materials testing, NIST-traceable spectroradiometric analyses, reflectance and spectral transmittance testing, and calibrations for light meters and light sources.

Solar Light is in the business of measuring the impact of environmental exposure. We believe that the societal risk and impact of environmental exposure is a long-term growth driver. Building on our 50+ year heritage of measuring and understanding the impact of solar UV,  we provide a complete range of solutions from selling products for our customers to do their own measurements, to offering the services of measurement to our customers.

Our customers choose us because we enable them to have confident data with which to make specific decisions. We strive to make our customers feel that we (including our channel partners) are invested in their success and partnered with their journey, rather than being a mere transaction seller. To do this well, we have to have scientific understanding of our customers’ applications so that we can provide solutions for them to obtain better, more accurate data. We are known as the industry expert which invests in driving the industry forward, to provide increasingly more effective and valuable tools to understand the impacts of environmental exposure on people, property and life.
