''For a healthy appearance of skin tones, it’s important to have sufficient spectral power in the upper part of the visible wavelength range. A red rendering index, R9 of 50 or higher, is one way of achieving this,'' said Kees Teunissen, Scientist Optics Light and Vision at Signify.
By applying Signify’s technology, the transition from CRI 80 to CRI 90 will not entail any significant loss of efficiency (lm/W) and so no loss of lumen - a unique achievement in the lighting industry.
The Color Rendering Index (CRI) represents the ability of a light source to render object colors faithfully in comparison with a reference light source. The transition from CRI 80 to CRI 90 affects the following available Philips products: FlexBlend, SmartBalance, PowerBalance, TrueLevel and TrueLine.
