Spectral Power Distribution

Radiometric Profile

Different light sources, such as fluorescent tubes and LEDs, have distinct radiometric profiles. Traditional fluorescent bulbs emit high amounts of energy in the ultraviolet range, which accelerates product spoilage. LEDs can be designed with a customized spectral power distribution that minimizes these harmful wavelengths while maintaining high visibility.

This customization reduces the risk of photo-oxidation in sensitive goods.

Package Interaction

Packaging materials must be selected to filter out the specific wavelengths that have the highest energy in the light source’s spectrum. If a warehouse uses lighting with a high blue-light component, the packaging must have a high absorbance in that specific band. This targeted protection prevents the light from reaching the product and triggering chemical reactions.

Such targeted design is common for bottled beverages and dairy products.

Preservation Strategy

Retailers use lighting profiles to balance the visual appeal of their displays with the shelf life of their products. Selecting light sources with low energy in the reactive bands protects the inventory from degradation. This operational control extends the time that products can remain on display.
