High CRI + R9: Rendering Reds Like Daylight

True color rendering goes beyond average scores. In architecture and retail, reds–whether lipstick, brick, or ripe fruit–reveal a light source’s real capability. Yuji Lux’s High CRI + R9 technology delivers exceptional red fidelity (R9 >90) alongside full-spectrum balance, ensuring materials look alive and authentic under every angle and intensity.

Why R9 Matters

R9 measures deep red rendering (R630–R660 nm), where most LEDs falter. Yuji’s approach boosts this critical range without sacrificing greens, blues, or neutrals.

Peak red output tuned to match natural daylight curves.
No magenta shift or desaturated pinks–common pitfalls in high-CRI alternatives.
Stable across dimming, voltage fluctuations, and temperature changes.

Skin tones, upholstery, food displays, and architectural accents gain depth and vibrancy that spec sheets alone can’t predict.

Technical Foundation: Full-Spectrum Phosphors

Yuji engineers multi-layer phosphor stacks to fill spectral gaps:

Blue peak precisely controlled to excite red and cyan phosphors evenly.
Extended tail into deep red (up to 700 nm) for natural warmth without amber bias.
CRI Ra95+, R9 95+, TM-30 Rf95+ verified on every production batch.

This results in light that handles mixed materials effortlessly – wood warms without yellowing, metals gleam without greenish casts, fabrics hold their intended hue.

Ideal Applications for R9 Excellence

High CRI + R9 shines where perception drives decisions:

Retail: cosmetics, fashion, food – products sell on first impression.
Hospitality: table linens, floral arrangements, skin under ambient glow.
Residential: artwork, leather, stone surfaces that define luxury.
Museums and galleries: preserving pigment accuracy without UV or blue-heavy distortion.

No Compromise to the Luminous Efficacy

It is always a dilemma when choosing between high CRI and better luminous efficacy (lm/W), as both are essential for high-quality LED lighting. Yujileds® optimizes technical solutions to balance efficacy with high CRI spectra and continues to develop solutions for even higher efficacy.
