LED Test & Measurement

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

ILT has a selection of systems to measure almost any LED Test and Measurement application. 

ILT meters come with NIST traceable, ISO 17025 accredited calibrations in units of Watts, Lumens, Watt/cm2, lux and foot-candles as well as full spectrum analysis.

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.

Input optics, including small cosine receptors, integrating spheres, narrow beam adapters and apertures (for testing uniformity) can be added to ILT systems making them the most versatile systems available.

ILT engineers and technical support staff are available to customize systems to the unique requirements of our customers.

Use the table below to identify the system (meter + detector) that meets your specific application.  Use the table to find the spectral range you wish to measure.  The table can be filtered to show our meters by type, (e.g., hand-held), as well as searching on the minimum and maximum spectral range you wish to measure.  The tables can also be sorted to group systems by meter type, spectral range, measurement range, and units.  Click the product link of the system to view it's details.
