This article explores the importance of high chromatic reproduction spectra and visual comfort in lighting settings of 3000K, 4000K, and 5000K, for optimal presentation of clothing and products. We focus on how the color fidelity index influences lighting schemes for products, ensuring that artificial light closely matches natural sunlight.
Apparel – 3000K
The 3000K lighting, with a color temperature of 3000 Kelvin, offers a warm light that enhances yellowish and reddish tones. This setting is ideal for colorful clothing, enhancing the richness and depth of these hues without altering the true color perception, thanks to a high color fidelity index. The color reproduction in this range with low blue light peaks helps perceive the real color of the product.
Although beneficial for cozy environments, it’s crucial to balance this lighting with adequate light intensity to avoid shadows that may distort the product’s shape.


Apparel – 4000K
A color temperature of 4000 Kelvin, or neutral light, is versatile for clothing lighting. This balanced spectrum effectively highlights the true colors of a wide range of tones without imparting a yellow or blue hue, always maintaining a high color fidelity index.
The 4000K lighting is particularly suitable for retail spaces where color precision and clarity are fundamental. Ideal for faithfully reflecting all tones and colors of products.


Product – 5000K
The lighting with a color temperature of 5000 Kelvin offers a cooler spectrum, ideal for products requiring accurate color representation under light simulating midday to midafternoon.
This setting is excellent for products with subtle color variations or that depend on chromatic precision for their valuation, such as electrical items, electronics, and general merchandise.
The 5000K light helps minimize chromatic distortions and enhances detail perception, crucial for evaluating product quality and finish.
What is R9 and Its Relevance in Product Lighting
R9 is a component of the Color Rendering Index (CRI) that evaluates how a lighting system reproduces the color red compared to a natural source.
This indicator is particularly important for applications where color precision is critical, such as in product lighting in stores or environments where colors must be presented precisely and attractively.
"A high R9 indicates better red color representation, a key point for attracting attention and improving the appearance of illuminated objects."
Visual Comfort
Besides chromatic fidelity, visual comfort is an important aspect to consider in product lighting.
Proper lighting should not only faithfully reproduce colors and define shapes but also prevent discomfort and ensure a pleasant visual experience for the viewer.
Light intensity, distribution, and glare minimization are key aspects to avoid visual fatigue.
In the 5000K setting, it is essential to balance high chromatic reproduction with a lighting design that evenly disperses light, reducing excessive contrast and glare for prolonged observation without discomfort.
