Ideally, this information
will be visible in the inventory, if available via GIA code.
will be listed in the operating point documentation.
The information can be found on a light:
on the serial plate.
The information can be found on an illuminant:
possibly printed on the old illuminant. The information can be deciphered as follows: 830 = 3000K, 840 = 4000K.
Light colour temperature can be determined clearly and correctly beyond any doubt using a measuring device. When evaluating which device is appropriate, please note that the value must not (only) be shown in coordinates, but directly in Kelvin (recommended measuring device: Gossen Mavospec Lite and Mavospec Base, prices: approx. CHF 2000).
