Consistent quality control in color-critical product categories is finally possible thanks to the SpectraLight QC light booth and luminaire. This holistic visual color assessment system features state-of-the-art light sources, including natural filtered daylight, making it easy to meet practically any specification. A data-driven back-end ensures inter-instrument agreement across the supply chain, allowing unprecedented reporting and traceability on unit settings, lamp performance, operator certifications, and more.

Benefits:

• Filtered tungsten halogen daylight provides the most accurate daylight simulation available for optimum visual assessment.
• Built-in sensors automatically adjust fluorescent lamp voltage to achieve instant stability and compensate for changes in lamp performance after many hours of use.
• Every instrument starts with exacting UV calibration. Built-in sensors monitor and correct UV output to maintain inter-instrument agreement.
• Real-time digital lux output can be adjusted to comply with ASTM and AATCC standards based on the sample type or user needs.
• X-Rite replacement lamps are marked with unique serial numbers to ensure consistent performance and better traceability.
• If you are moving to an LED light source, our LED lamp kit is an excellent option for your light booth. It provides exceptional color rendering using the same hybrid technology as the LED-BH1 CIE illuminant. This lamp kit is sold separately.

The following table of VeriVide lamps for viewing cabinets covers all supply chain viewing conditions, including the specific requirements of individual major retailers.

Retailers have differing specifications for the lamps and grey used in the Colour Assessment Cabinets. VeriVide equipment provides these conditions for all applications. For consistency, the source of light must be controllable and constant. To understand light sources, two factors need to be considered:

1. COLOUR TEMPERATURE – expressed in Kelvin. (K)
   Colour temperature describes the colour appearance of the lamp itself and the light it emits and can vary along with its spectral power distribution. “Correlated” colour temperature applies to fluorescent lamps and approximates the true colour temperature.

• Lamps with lower colour temperatures appear warmer i.e. red/orange and typical examples would be illuminant A and 830.
• Lamps with a higher colour temperature look bluer, and examples would include the VeriVide D65 and D75.

2. COLOUR RENDERING INDEX (CRI)
   ​A numerical system that measures how well colours are rendered by a lamp in comparison to a reference light source. The CRI is measured on an index from 0-100, with 100 representing an exact match, whilst low values indicate poor colour rendering.

• Therefore a lamp rated with a CRI of 98 such as the VeriVide D65 will show colours more accurately than a lamp with a CRI rating of 62 such as the CWF.

This rating method is recognised by the Illuminating Engineering Society (IES) and the Commission International de L’Eclairage (CIE).
