The low thermal conductivity minimizes thermal losses in the lamp while in the operating state, and the low ionization potential causes the breakdown voltage of the gas to be relatively low in the cold state, which allows the lamp to be easily started.
LPS svetilkam se malo poveča električna poraba približno 10% do konca njihove življenjske dobe, ki je običajno okoli 18.000 ur za sodobne svetilke.
