Spectroradiometers can be used to measure blue light, providing spectral power distributions (or spectral radiance) and peak wavelengths. Using a spectroradiometer, monitors and cell phones can be tested for spectral distribution to identify normal operating mode, the effect of reducing blue operating mode, the effect of adding yellow filters, and the effect of adding yellow filters and reducing the blue mode. By turning down the blue in monitors, using yellow filters and adding 480 nm LED lighting, research can be done to determine the impact on humans\u2019 EEG patterns of alertness and increased performance on cognitive tests.
