All lamps are explicitly designed with sustainability in mind.
For example, only recyclable and durable materials are used that can be easily disassembled and separated.
Preservation of old materials is done with natural and environmental friendly means.
The re-use of authentic materials in this context can also be seen as a recycling that actually goes even further.
According to the philosophy of Cradle2Cradle one can even speak of "upcycling".

Furthermore, each lamp is very energy efficient through the use of LED lighting, which guarantees also a long life.
However, since each lamp is a unique piece of cultural heritage, which one doesn't discard but passes on to future generations, the products are themselves sustainable.

Finally, to ensure that future generations can also enjoy the monuments, a part of the revenue returns to the monument for future maintenance and restoration.
