Fresh Lighting Ban: Technical Specifications and Testing Requirements for Edible Agricultural Products Lighting

In July 2023, the State Administration for Market Regulation announced the "Measures for the Supervision and Administration of Quality and Safety of Edible Agricultural Products Market Sales", which came into effect on December 1, 2023. Among them, the ban on "fresh lighting" became a prominent highlight. The corresponding formulation of "T/GIES 018-2023 Technical Specification for Light Sources and Luminaires for Edible Agricultural Products Lighting" has standardized industry practices and guided production and use units to standardize the use of light sources and luminaires for edible agricultural products lighting. Currently, some provinces have formulated technical specifications for light sources and luminaires for edible agricultural products lighting, providing law enforcement basis for local market supervision departments, and giving direction to related enterprises and technical research and development in subsequent R&D and production. This article will introduce in detail the concept of "fresh lighting", specification requirements, and measurement methods for technical parameters, focusing on the requirements for color rendering index in the edible lighting field and how to use spectrometers for precise measurement, to help everyone better understand and apply relevant standards. Yiming Technology, as a professional LED lighting testing equipment manufacturer, has rich experience and technical accumulation in the field of edible agricultural products lighting testing.

I. Introduction of Standards: Fresh Lighting Ban and Edible Lighting Technical Specifications

In July 2023, the State Administration for Market Regulation announced the "Measures for the Supervision and Administration of Quality and Safety of Edible Agricultural Products Market Sales", which came into effect on December 1, 2023. Among them, the ban on "fresh lighting" became a prominent highlight. The corresponding formulation of "T/GIES 018-2023 Technical Specification for Light Sources and Luminaires for Edible Agricultural Products Lighting" has standardized industry practices and guided production and use units to standardize the use of light sources and luminaires for edible agricultural products lighting.

Currently, some provinces have formulated technical specifications for light sources and luminaires for edible agricultural products lighting, providing law enforcement basis for local market supervision departments, and giving direction to related enterprises and technical research and development in subsequent R&D and production. The introduction of these specifications marks a new stage of standardized development in the edible agricultural products lighting industry, which is of great significance for protecting consumer rights and promoting healthy industry development.

II. What is "Fresh Lighting"? Definition and Working Principle

"Fresh lighting" is a type of cold light source lighting fixture. The closer the color rendering index of the light is to 100, the more it deepens and intensifies the color of objects, making the colors seen by the human eye more vivid than those under natural light. "Fresh lighting" enhances specific color emissions and changes the luminaire's color rendering ability for specific colors, such as red and green, making food colors appear more rosy or vivid, thereby stimulating consumers' purchasing desire.

Although this special lighting effect can beautify the appearance of food, it may mislead consumers' judgment of the actual quality of food. The food colors seen by consumers under "fresh lighting" differ from those under actual natural light, which may lead to deviations in purchasing decisions. Therefore, banning "fresh lighting" helps protect consumer rights and ensures that consumers can see the true colors of food. This is also an important reason why "T/GIES 018-2023 Technical Specification for Light Sources and Luminaires for Edible Agricultural Products Lighting" requires edible lighting products to meet strict color rendering index standards.

III. Technical Requirements of the Specification: Edible Lighting Color Rendering Index Ra, Rg, Rf Standards

According to "T/GIES 018-2023 Technical Specification for Light Sources and Luminaires for Edible Agricultural Products Lighting", light sources and luminaires for edible agricultural products lighting need to meet the following technical requirements:

1. Pass national CCC product certification and obtain CCC certificate. This is a basic requirement for products to enter the market, ensuring that products comply with national mandatory certification standards. CCC certification is a fundamental requirement for edible lighting product compliance.
2. The initial value of general color rendering index Ra should be no less than 90 and no less than 3 values of the nominal value. Color rendering index is an important indicator for measuring the light source's ability to restore object colors. The higher the Ra value, the more accurate the color restoration. Requiring the initial Ra value to be no less than 90 ensures that the light source has good color rendering performance and avoids excessive beautification of food colors. This is an important standard that distinguishes edible lighting from ordinary lighting and requires precise measurement using spectrometers.
3. Color saturation Rg should be in the range of 90-110 and should not deviate from the nominal value by ±3 values. Color saturation reflects the degree of color enhancement by the light source. Rg values in the 90-110 range ensure that food colors are neither excessively beautified nor appear dull, maintaining a natural and realistic visual effect. Color saturation Rg is one of the key parameters in edible lighting technical specifications and needs to be measured through integrating sphere spectrometer testing systems.
4. Color fidelity Rf should be no less than 90 and no less than the nominal value. Color fidelity is an important parameter for measuring the authenticity of color restoration by the light source. The higher the Rf value, the more authentic the color restoration. Requiring Rf to be no less than 90 ensures that consumers can see the true colors of food. Color fidelity Rf together with color rendering index Ra forms the color quality evaluation system for edible lighting products.
5. Color temperature should be in the range of 2700K-6500K and within the allowed color temperature error range. The selection of color temperature range should consider both the aesthetics of food display and ensure that it does not excessively change the visual presentation of food. The 2700K-6500K range covers common color temperatures from warm white to cool white, meeting the display needs of different foods. Color temperature is an important parameter for edible lighting products and can be accurately measured using spectrometers.

The formulation of these technical requirements aims to standardize the production and use of light sources and luminaires for edible agricultural products lighting, ensuring that food colors appear true and natural under lighting, protecting consumer rights, and promoting healthy industry development. As an emerging lighting application field, edible lighting has stricter requirements for color rendering index, which requires precise measurement through professional spectrometers. Only by using integrating sphere spectrometer testing systems that meet standards can accurate measurement of parameters such as color rendering index Ra, color saturation Rg, and color fidelity Rf be ensured.
