At the Hamburg aluminum smelter, a completely renewed lighting system provides the necessary brightness in the plant halls. The ceilings of the three electrolysis halls were fitted with new LED luminaires in May.
This was a considerable amount of work, as a total of 540 sodium vapor lamps, which had previously provided light at a height of twelve meters, had to be replaced with modern light-emitting diodes. Installation during ongoing operations went smoothly and was even completed two weeks ahead of schedule. The retrofit has several advantages.
