Low-intensity use

When using your system with very low intensity, the spectral measurement values will start to
fluctuate. The lower the intensity, the higher the fluctuation. The generated light is still stable up to a
certain point. The fluctuation of the values is caused by the noise of the spectral measurement of the
internal spectrometer. The light intensity will continue to get lower when the influence of the noise
continues to get higher. When using standard illuminants with an intensity lower than 25 lux, it will no
longer be possible to get a correct value.
