We got to be part of renewing Levi ski center's lighting. At the installation moment, the winter was still far ahead as is seen in the pictures. The old lights were removed and changed to new ones with the help of cranes.
The old lights were changed to SteraLux AREA LED lights. We used AREA 480 lights that were customized to suit the use. The goal of the change was to save energy and have no maintenance need.
