Candela to lux calculation
Candela tp lux calculation with distance in feet
The illuminance Ev in lux (lx) is equal to 10.76391 times the luminous intensity Iv in candela (cd),
divided by the square distance from the light source d2 in square feet (ft2):
Ev(lx) = 10.76391 × Iv(cd) / (d(ft))2
Candela tp lux calculation with distance in meters
The illuminance Ev in lux (lx) is equal to the luminous intensity Iv in candela (cd),
divided by the square distance from the light source d2 in square meters (m2):
Ev(lx) = Iv(cd) / (d(m))2
