Industrial lighting needs to be particularly robust: high, or even low, ambient temperatures, humidity, particles of dust and dirt or aggressive chemicals make particular demands on lighting systems. Room heights and workplace directives for light intensities need to be taken into account. At the same time, energy costs and CO2 emissions must be reduced. The right lighting can also help to increase performance and productivity and therefore allow the company to retain its competitive edge. With RZB, Union Steel found the right solution for all its requirements for its production facilities: LED hall downlights from the Ralite range combined with light control +3 for a reliable and constant light output.
