Great lighting is not just bright - it makes materials feel right. 💡
For premium retail, luxury residential and art-focused interiors, three specifications do different jobs:
🎯 2-Step SDCM controls chromaticity tolerance around a target - but the acceptance geometry still needs to be defined.
🎨 Ra >97 supports strong average colour fidelity.
❤️ R9 >90 helps preserve saturated reds in skin, timber, leather, textiles, food and artwork.
The strongest specification balances colour consistency, fidelity and complete-luminaire performance - zone by zone.
