A qualitative quantum leap in museum lighting
Relighting the museum took a whole year because installing and commissioning the lighting could only be carried out on closing days. The project, technically supervised by lighting designer Karsten Krause, was implemented from department to department in close co-operation with the specifically responsible curators. At the beginning, some of his colleagues were sceptical about the relighting, admitted Hoppe. However, the new light spoke for itself and after that it couldn't be installed quickly enough for the curators. In the end everyone was completely satisfied.
The figures are also impressive: by converting to LED technology the museum is able to save annual energy costs of 125,000 euros. This corresponds to a reduction in CO2 emissions of 395 tonnes. Hoppe would not be doing his job as an expert in museum management if another effect of the relighting was not just as important – the quantum jump in quality of the museum lighting. "The new light allows both us and the public to discover things we never saw before. It's particularly noticeable in the railway exhibition. We can now see the construction details on the black steam locomotives that were extremely difficult to illuminate, and the innate aesthetic style of the machines can be distinguished." Hoppe was also enthusiastic about the ERCO Spherolit lenses that give variability and flexibility to the luminaires: the simply exchanged lenses mean that the museum team can also fine-tune and readjust the light at a later date.
