Field measurement of Floodlighting Utilisation Factor

The main purpose of this work is to present a method and some examples of field measurements of the parameters known as floodlighting utilisation factor (FUF) and relative loss of luminous flux. The measurements were performed using a traditional luminance meter with a specified measuring area. The results of these measurements, which were made on two selected floodlit objects (The Center for Foreign Missions Veterans in Warsaw and the Monastery in Wegrów), are also shown and precisely commented on in this work.
