Kuat Sinar ( Lux) = luas ruangan 1 m2 terdapat arus sinar sebesar 1 Lumen

Kuat Sinar ( E ) = h x Q / A

Dimana Q = Arus sinar ( Lumen = Lux / m2)

A = Luas Area ( m2)

h = Faktor kegunaan

Misal

Luas ruangan = 8 m x 10 m = 80 m2

Faktor kegunaan = 0.45

Berapa buah lampu yang di butuhkan untuk ruangan sekolah , lampu TL 40 W

E = (h x Q )/ A = (h x n x Lampu ) / A = > n = (E x A )/( Lampu x h )

N = 110 x 80 / (3350 x 0.45 ) = 5,8 = 6 buah

                               Faktor      Target Penerangan           Lux/m2
