Supermarket Flower Arrangements and Floral Display Case Lighting

Impulse buying accounts for a large proportion of supermarket flower arrangement sales. Floral display cases must be brightly lit for optimal supermarket floral merchandising, yet hot spotlights can cause fresh flowers to wilt.

UV radiation also contributes to flower wilting, and accelerates the decomposition process, shortening the shelf life of cut flower displays. PROMOLUX lamps emit 86% lower UV than most floral display case lighting and can increase shelf life of fresh cut flowers by up to 50%, depending on the variety of the flower.

True color rendering is essential for impulse sales of all floral bouquets. Promolux lamps have a balanced color spectrum, unlike other lamps that distort the beauty of flower arrangements by emphasizing yellow and not including enough of the red and blue segments of the spectrum. Promolux high definition fluorescent lamps are ideal for ambient and display case applications, while Promolux halogen lamps and spotlights provide safe and effective accent lighting.

Cut Flower Bouquets in Floral Department Merchandisers

Although the heat and ultraviolet light radiated by most floral display case lamps are healthy for living plants, they accelerate the organic decomposition of harvested flowers and can contribute to dehydration. UV radiation in floral display case lighting encourages cut flowers to bloom, triggering them to release higher than normal levels of ethylene gas in a photochemical reaction that causes the blossoms to open and eventually decompose.

Like a domino effect, this ambient ethylene gas causes other cut flower buds in supermarket floral display cases to bloom, become overblown, and decay prematurely. Even if ethylene is absorbed from the atmosphere by sachets or filters, ethylene is continually being produced by flowers illuminated by display case lighting. Roses and spring flowers such as daffodils, tulips, and irises are particularly sensitive to light radiation.

Increased surface temperatures from display case lighting can encourage bacteria to grow, causing flowers to ferment and decompose. Floral display case lamps that lead flower buds to bloom prematurely, wilt, or ‘blast’ and fall off, are responsible for increased product shrinkage and lost sales.

Ideally, cut flowers should be kept in dark, cool, and humid conditions to prolong their fresh appearance. However, flowers are often sold on their visual appeal so these storage conditions are not always possible to achieve. Shoppers expect commercial flowers to last at least one week, yet it often takes 5 to 7 days for the flowers to reach the retailer once they have been harvested. Flowers that look like they have not yet reached their prime and will last a long time are the most visually appealing.

It is imperative therefore for floral shops to sell their stock in a very short time and to keep their flowers fresh by storing them in cool temperatures and protecting them from the premature damage caused by heat and radiation. Promolux lamps combine true color rendering with low levels of damaging visible spectrum and UV radiation, prolonging the shelf life of floral displays while showcasing them to best advantage and helping them to sell quickly.

Silk Flowers in Retail Floral Showcases

True color rendering is an essential aspect of retail floral lighting especially for silk flowers. Supermarket fluorescent lighting emphasizes the green and yellow wavelengths of the visible spectrum, while shortchanging the red and blue wavelengths, which makes white flowers appear yellow or greenish, and red flowers seem brownish. Promolux lamps emit a more balanced range of wavelengths, including more of the red and blue wavelengths and more moderate levels of the yellow and green wavelengths. Under Promolux floral display lamps, silk flowers are vibrantly colorful.
