Spectral Power Distribution Charts

The charts below are representative Spectral Power Distribution (SPD) graphs of our accelerated weathering light sources as compared to sunlight. A variety of filter combinations are available for our Xenon and Metal Halide light sources (see page 9), which can help alter the SPD to provide the closest match to your end-use environments.
