CAC cabinets are usually fitted with 4 or 5 different light sources. A standard daylight source: CIE D65 or CIE D50 (can sometimes be supplied with both), one or two Point of Sale illuminants such as 840P15, CWF, or LED, UltraViolet for the detection of optical brightening agents, and a tungsten filament source; CIE A or VeriVide F.
Viewing your product under a variety of different standardised light sources will highlight any manufacturing problems such as metamerism and ensure the colour and appearance will be acceptable to the consumer in real world lighting conditions.
