Table 14.4
Typical luminaire maintenance factors
The lighting lumen method tool reads a luminaire maintenance factor here. You choose the lamp chamber class, the pollution category and the cleaning interval. The tool multiplies that factor by the lamp lumen maintenance factor you type, as the table leaves lamp depreciation out. The table is for road lighting, so check the factor for an interior.
