    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
