VeriVide D65 “Artificial Daylight”. Correlated colour temperature 6500K and CRI 98. Within the tolerances prescribed in BS 950: Part 1; and all international specifications for D65 illluminant. Specified for most applications where there is a need to maintain colour consistency and quality. Conforming highly to the CIE specifications, for accurate colour matching.
VeriVide lamps for viewing cabinets covers all supply chain viewing conditions, including Artificial Daylight (D65 or D50), UV, Cool White, Filament and specific requirements of individual major retailers. For colour consistency, the source of light must be controllable and constant and two important factors need to be considered:
- 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.
- 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).
