Daylight Simulation in SPL III and Judge II

The Spectralight III uses a Tungsten Halogen lamp filtered with a certain blue glass-filter to an excellent match of the CIE Standard illuminant D65. This has a Color Rendering Index of 95.
The Judge II uses the Macbeth 7-phosphor-fluorescent tube, which shows as every other fluorescent tube so called energy peaks at certain wavelengths, where the phosphors show most of their energy. Due to that, the simulation is not that good as with a SpectraLight, but it also reaches a CRI of 94, which is an excellent simulation.
