This measures a light and rates it from 1-100 based on the spectral similarity to another known light source.
The two most common sources for comparison are the Standard Illuminants of Tungsten (3200K) and CIE D55 (Daylight/5503K).
The SSI data in this table is measured in the following ways:
Tungsten (3200K): The light is set to 3200K or as close as possible
D55: The light is set to 5500K or as close as possible
