We renewed the lighting of a large logisticscentre in Vuosaari,Helsinki, together with Helsingin Talotekniikka Oy. The lighting was renewed with SteraLux LINEAR lights. The project started with a lighting plan and an energy saving plan as well as a repayment plan for the investment. The old lights were changed to SteraLux LINEAR 150W and 70W lights. The new lights changed the colour temeperature from 2700 kelvin to 5000 kelvin. The change came with more light and a clear light colour instead of a yellow one.
