About Us

With over 40 years of combined experience in photometry and testing, our staff is committed to helping our customers to achieve their goals with a focus on quality, integrity, and service. The testing equipment used for measurements was selected carefully for accuracy and customization. We use a LightLab International Type-C goniometer with photometer and spectroradiometer measurement capabilities. This highly accurate instrument is capable of measuring the color and intensity of light emitted in all directions from a lamp or luminaire. Test angles can be selected in custom Group of three colleagues, one man on a cell phone and two womenincrements to fit the testing needs of all types of customers. Color Quality Testing is performed using either our Labsphere 2m integrating sphere or our LightLab gonio-spectroradiometer.

More Than Just Accredited Testing…..

Although we have a broad scope of accreditation, we are focused on providing the kind of personalized testing that the larger laboratories aren’t capable of. In addition to our commitment to individualized service, we also bring the integrity and experience of a highly knowledgeable staff to our services.
