§White light consists of radiation that possesses different wavelengths (spectral colours).§
The individual wavelengths correspond to individual colours.
Light can be measured differently. The type of measurement is chosen following the main point of interest:
- Quality of lightsource > Luminous flux (Lumens)
- Quality of optics / Divergence angle > Light-intensity (Candela)
- Quality of optics / Light range > Illuminance in defined distance (Lux)
