Challenges of LED Measurement

LEDs are taking the lighting industry by storm. Applications requiring light output ranging from UV to NIR are replacing traditional light sources with LED technologies.

Though LEDs have the advantages of increased efficiency, color specificity, size, response time and long lifetime, LEDs often struggle with repeatability in color temperature, spectrum, peak wavelength, and intensity. This makes the need for accurate, easy-to-use test and measurement equipment more important than ever.

International Light Technologies has a full complement of powerful, easy-to-use and highly accurate LED light measurement systems. The ILT950, ILT950UV and ILT350 Spectroradiometers for excellent for characterizing discrete LEDs and LED modules for spectral output, light output, CRI, CCT, RA and more. The Light Meter line includes hand-held and research grade light meters for radiometric and photometric analysis.

ILT LED measurement systems include N.I.S.T. traceable and ISO 17025 accredited calibrations to allow measurement of absolute spectral intensity values (in watts, joules, W/cm2, W/sr, lumens or candela).

ILT systems are designed to measure individual LEDs, lights sources, lamps and displays from the lab and product development stage through production and quality control, repeatability/reliability verification and end user implementation.

ILT also offers a selection of our calibrated light measurement tools for rental as well as LED testing at our in-house calibration lab.
