LED Test and Measurement Systems

International Light Technologies has a full complement of powerful, easy to use, and highly accurate LED light measurement systems and tools such as the ILT950 Spectroradiometer LED Measurement System (that includes an Integrating Sphere), the most cost effective system for characterizing discrete LED’s and LED modules for spectral output, absolute intensity, power, and color.

Challenges of LED Measurement

LED’s present certain measurement challenges inherent in their design such as their narrow viewing angle, near-monochromatic light, and limited wavelength selection.

This is further complicated by the confusing use within the industry of various measurement units for qualifying LED output such as candela (both spherical and beam), candlepower (older term for candela), foot-candles or lux (illuminance), watts per square centimeter (irradiance), and lumens or watts (power).

Color, once a subjective human perception, in an attempt to define and standardize its use, has become a complicated LED specification to measure, with terminology like color coordinates, color temperature, dominant/complementary wavelength, Color Rendering Index (CRI) and Correlated Color Temperature (CCT).
