YUJI NormLite™ CRI 98 11W bulb comes in a very small A19 form factor and standard E26/E27 screw-in base, which works in all standard lamp fixtures or clip-on lamp or table lamps. Replaced your current light bulb with Yuji NormLite™ D65 bulb, it will significantly enhance your color performance in your color matching.

Full spectrum/Sunlight

YUJILEDS® sunlight technology gives innovative and revolutionary solutions providing unprecedented Spectral Power Distribution (SPD) with ultra-homogeneous features. It mimics the natural light spectrum up to 99% similarity to the spectral engineering level, where a standard LED spectrum generally misses significant radiance and only constitutes less than 50% of the sunlight spectrum.

98 CRI, R9 95 Rated LED Bulb
Colour Temperature: 6500K(CCT), D65(CIE)
Accurate Chromaticity Coordinate:(u’10= 0.1979, v’10=0.4695), ΔE≤0.005
Simple and Easy-to-install

Works in all standard lamp fixtures, including easel clip-on lamps, floor lamp and table lamps.

NormLite™D65 — Precision Color Evaluation, Now in an A60 Bulb

The NormLite™ D65 brings CIE Standard Illuminant D65 simulation into a compact, energy‑efficient A60 LED bulb. Designed to meet the stringent requirements of ISO 3668, ASTM D1729, and DIN 6173‑2, this bulb enables manufacturers, quality control labs, and industrial professionals to assess color with confidence — under a light source that faithfully reproduces average northern sky daylight.

Unlike bulky light booths or fluorescent tubes requiring dedicated fixtures, the NormLite™ D65 fits standard E26/E27 screw‑in sockets. Install it in existing desk lamps, overhead fixtures, or clamp lights to transform any workspace into a standard‑compliant color evaluation station.

Full‑Spectrum Sunlight Technology

Full‑Spectrum Sunlight Technology

YUJILEDS® proprietary sunlight LED technology delivers unprecedented Spectral Power Distribution (SPD) that mimics natural daylight with up
to 99% spectral similarity to the engineered daylight standard. Conventional LEDs lack significant radiance in critical spectral bands, covering less than 50% of the true D65 spectrum. The NormLite™ D65 closes that gap, providing a continuous, homogeneous output over visible spectrum.

Engineered to Meet Industrial Color Matching Standards

Engineered to Meet Industrial Color Matching Standards

The NormLite™ D65 is certified to meet or exceed multiple international standards for color viewing:

• ISO 3668 — Visual comparison of the color of paints
• ASTM D1729 — Standard practice for visual appraisal of colors and color differences of opaque materials
• DIN 6173‑2 — Color matching under standard illuminants

With a Correlated Color Temperature (CCT) of 6500 Kelvin, the NormLite™ D65 reproduces “average daylight from the northern sky” — the internationally recognized reference for industrial color assessment.

Where D65 Is the Industry Reference

The CIE Standard Illuminant D65 is mandated or referenced in color matching standards across a broad spectrum of industries:

•Automotive & Aerospace — Color consistency of interior trims, exterior paints, and plastic components
•Textiles & Fabrics — Color sorting, shade matching, and quality assurance
•Paints, Coatings & Finishes — Batch‑to‑batch color verification under standardized lighting
•Plastics & Polymers — Masterbatch evaluation and molded part color assessment
•Paper & Packaging — Printing substrate evaluation and packaging color control
•Food & Agriculture — Visual quality inspection and color‑based grading
•Pharmaceuticals & Chemicals — Color consistency of APIs, coatings, and raw materials
•Furniture & Wood Finishes — Stain and topcoat color matching

…and any application where “average daylight” is the agreed‑upon reference for visual color comparison.

Why D65？D65 vs. D50 — Understanding theDifference

While D50 (5000K) is the preferred illuminant for the graphic arts industry — where printed materials are evaluated for soft‑proofing and press proofing — D65 (6500K) is the industrial standard for colored materials, surfaces, and finishes.

•D65 (6500K, cooler, slightly blue‑white): Simulates average northern sky daylight. Mandated by ISO 3668 and referenced in ASTM D1729 for visual matching of paints, coatings, plastics, textiles, and automotive components.
•D50 (5000K, warmer, neutral‑white): Preferred for the graphic arts industry (ISO 3664) and ICC color management workflows.

Choose D65 if you evaluate physical products — from automotive parts to plastic housings to dyed fabrics. Choose D50 if you evaluate printed matter or work in graphic arts.

Simple and Easy to Install

Simple and Easy to Install

The NormLite™ D65 features a standard E26/E27 screw‑in base (A60 bulb shape) and works in virtually any lamp fixture:

•Easel clip‑on lamps
•Table lamps and desk lamps
•Floor lamps and task lights
•Overhead fixtures with standard Edison sockets

No ballast, no external driver, no special wiring — simply screw in and begin
standard‑compliant color evaluation.

    Bringing the Sun Indoors: How YUJILEDS is Redefining Healthy Lighting

    Have you ever felt that something is just "off" with your indoor lighting? You might have the perfect lamp, but the light feels flat, harsh, or somehow unnatural. The culprit is often the quality of the light spectrum itself.

    For decades, artificial lighting has been a compromise. We traded quality for efficiency, accepting dull colors and eye strain in exchange for lower energy bills. But what if you didn’t have to choose? What if you could have lighting that is not only energy-efficient but actually beneficial for your wellbeing?

    Enter YUJILEDS, a pioneer in sunlight simulation technology. Their mission is simple yet revolutionary: to harness the full power of the sun’s spectrum and bring it into your home or workspace.
