The required value of the luminous flux (in Lumens) is determined by the formula, the norm of illumination is multiplied by the area of the room and multiplied by the correction factor. For a standard ceiling height (2.5-2.7 m), this coefficient is equal to unity. Total we get 300 Lx x 6 sq.m x 1 = 1800 Lm. Select incandescent bulbs for this value.
Luminous flux of conventional incandescent lamps:
25 W = 220 Lm
40 W = 415 Lm
60 W = 710 Lm
75 W = 935 Lm
100 W = 1340 Lm
