In the past the concepts designed for the retail market were based on a high degree of illumination, even for ground-level lighting. Not infrequently the average level was around 2,000 lux, with a power input of more than 45 W/m².

The important highlighting of products on a level with people’s lines of vision could only be achieved using powerful lighting systems. Many concepts called for the use of HIT 70 W lamps. Using the old technology the spotlight systems needed to have correspondingly large dimensions.

Often, the spotlights on power rail systems consisted of two visible components – the equipment housing and the spotlight head itself, equipped with the bulb and reflector technology. By contrast, current innovative lighting concepts adhere to a certain basic energy-related concept, achieving a good presentation of products that promotes sales despite a considerably lower power input, one of less than 20 W/m². The relevant

concepts are usually very rich in contrasts: With a low basic level of illumination (between ca. 600 and 1,000 lux) the customer’s gaze is directed by the strong accentuation of the goods and of the rear walls or displays, allowing retail space to be transformed into a stage. With the current LED technology product developers are in a position to implement lighting systems in small areas.

The heat management system, synchronized with the integrated LED technology,and the replaceable optics made of highly reflective MIRO-SILVER (total reflectivity of up to 98 percent) allow for luminous efficiency of up to 2,830 lumens. This corresponds to 91.3 lm/W with a system output of only 31 watts. All the important luminous colours from 2,700 to 4,000 kelvins are standard with a colour rendering of up to CRI 95.
