The greater the familiarity of a monument or the bond with it, the more value is added.
This is very personal. Everybody has his own story.
That story becomes even more beautiful because as the owner of a SemperNovum lamp you get special privileges, such as special receptions and guided visits.
The USB stick is the access key for this.

It is also possible to make the lamps even more personal.
This can be done by providing your own material with which you have a special or emotional relationship.
Think e.g. of the parental house, a monument from the hometown / birthplace, or a remarkable, centuries old tree that has to be cut.
