Light Warmth Spectrum

Color Temperature (Kelvin Scale)

Color temperature describes the visual warmth or coolness of light, measured in Kelvin (K). Warm light creates cozy ambiance; cool light enhances alertness.

2200K – 2700K (Warm White)

Candlelight amber glow. Ideal for bedrooms, dining rooms, and evening lamps.

3000K – 3500K (Soft / Neutral White)

Friendly, balanced illumination. Recommended for living rooms, kitchens, and bathrooms.

4000K – 5000K (Cool White / Daylight)

Crisp, energizing clarity. Best for home offices, reading desks, and workshops.

Color Fidelity

CRI (Color Rendering Index)

CRI measures a light source’s ability to accurately reveal the true colors of objects compared to natural sunlight (CRI 100).

CRI 90+ (High Fidelity)Premium Quality

Mandatory for bathroom vanity mirrors, kitchen food prep, artwork, and photography. Skin tones look natural and vibrant.

CRI 80 – 89 (Standard)Acceptable

Good for general hallway illumination, closets, and utility rooms where precision color discrimination is not critical.

CRI < 80 (Low Fidelity)Avoid

Causes washed-out, dull, or sickly color appearance. Inexpensive generic LED bulbs often suffer from poor CRI.
