Illuminance in lux (lx) to luminous flux in lumens (lm) calculator and how to calculate.

Enter the illuminance in lux (lx), select area unit type, enter radius in meters for spherical light source or surface area

in square meters for any light source and press the *Calculate* button to get the luminous flux in lumens (lm):

The luminous flux *Φ*_{V} in lumens (lm) is equal to 0.09290304 times the illuminance *E*_{v} in
lux (lx) times the surface area *A* in square feet (ft^{2}):

*Φ*_{V(lm)} = 0.09290304* *×*
E*_{v(lx)}* *×* A*_{(ft}2_{)}

So The luminous flux *Φ*_{V} in lumens (lm) is equal to 0.09290304 times the illuminance *E*_{v} in
lux (lx) times 4 times pi times the squared sphere radius r in feet (ft).

*Φ*_{V(lm)} = 0.09290304* *×*
E*_{v(lx)}* *×* *4⋅π⋅*r*_{(ft)}* *^{2}

So The luminous flux *Φ*_{V}
in lumens (lm) is equal to the illuminance *E*_{v} in lux (lx) times the surface area *A* in square meters (m^{2}).

*Φ*_{V(lm)} = *E*_{v(lx)}* *×* A*_{(m}2_{)}

So The luminous flux * Φ*_{V} in lumens (lm) is equal to the illuminance *E*_{v} in
lux (lx) times 4 times pi times the squared sphere radius r in meters (m).

*Φ*_{V(lm)} = *E*_{v(lx)}* *×*
*4⋅π⋅*r *^{2}_{(m}2_{)}

What is the luminous flux on a surface of 4 square meters and illuminance of 300 lux?

*Φ*_{V(lm)} = 400 lux × 4 m^{2} = 1200 lm

What is the luminous flux on a surface of 4 square meters and illuminance of 700 lux?

*Φ*_{V(lm)} = 700 lux × 4 m^{2} = 2800 lm

What is the luminous flux on a surface of 4 square meters and illuminance of 890 lux?

*Φ*_{V(lm)} = 890 lux × 4 m^{2} = 3560 lm

What is the luminous flux on a surface of 5 square meters and illuminance of 11000 lux?

*Φ*_{V(lm)} = 11000 lux × 5 m^{2} = 5500 lm

What is the luminous flux on a surface of 7 square meters and illuminance of 800 lux?

*Φ*_{V(lm)} = 800 lux × 7 m^{2} = 5600 lm
