Lux to Lumens calculation formula |
||
Calculation with area in square feet 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_{(ft2)} 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} |
Calculation with area in square meters 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_{(m2)} 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}_{(m2)} |
