The copper lanterns in front of the New Palais in Potsdams Park Sanssouci are replicas of former gas lanterns - now with LED technology.

In residential neighbourhoods in Berlin and other European cities, gas lanterns are associated with warm and comfortable lighting. Their poor energy efficiency was a threat to their romanticism however. Using energy-saving, low-maintenance LED replacements, it has been possible to conserve both their memory and highly distinctive effect.
