Pro-Lite provides equipment and measurement services for testing the output (power, brightness, colour, spatial distribution) of LEDs, LED arrays and clusters and any LED-based product. We also provide software design tools and run training courses in the basics of light measurement (radiometry, photometry & colorimetry). In more detail, we supply:

Integrating spheres and integrating sphere-based light measurement systems from LABSPHERE. Measure total flux (Watts, lumens), intensity (candelas) as well as colour temperature, dominant wavelength, chromaticity and colour rendering.

ProMetric™ CCD-based imaging photometers and colorimeters for 2-dimensional display, projector and LED testing from RADIANT IMAGING. Measure luminance, illuminance and chromaticity at millions of positions in just a few seconds.

Radiant Source Model™ from RADIANT IMAGING are industry-standard data files containing spatial light measurements for all the leading brands of LEDs and lamps. A Radiant Source Model is a near-field goniometric mapping of an LED’s luminous intensity distribution. Together with our ProSource™ software, a Radiant Source Model outputs rays into industry-standard optical design and ray-tracing software and dramatically improves the accuracy of the computer prediction of the optical design.

Measurement Services available from Pro-Lite include integrating sphere testing of LED luminous and spectral radiant flux for any size and power of LED or LED cluster, including colorimetric properties. Also available are contract measurement services of the luminance and colour variation of an LED array using a ProMetric™ CCD photometer and near-field goniometric measurements of LED spatial light intensity and the recording of custom Radiant Source Models™.

For those who are new to LEDs and how to measure them, Pro-Lite offers a one-day training course on the science of radiometry, photometry, colorimetry and spectroradiometry.
