Initial product installation cost
inserire 0 in caso di impianto esistente, altrimenti inserire il valore stimato di costi installazione prodotti. Il valore può essere compreso tra 20% (grandi impianti) e 50% (piccoli/medi impianti) del costo totale di acquisto dei prodotti illuminanti, a seconda della complessità di installazione. Questo valore va comunque preso come indicativo, per un calcolo accurato si consiglia di valutare autonomamente i costi di installazione.
