Footcandles and lux can be converted as follows:
1 footcandle = 10.76 lux
1 lux = 0.0929 footcandles
Light must be evaluated based upon the sensitivity
of the human eye in accordance with the interna-
tionally accepted definition for the spectral
response, V(
λ
), of the human eye which is adjusted
to bright light. This response curve represents the
mean value which was determined based upon
tests conducted with a large number of persons.
The integrated silicon photodiode has been so well
matched to the spectral response of the human eye
through the use of filters, that it has achieved a rat-
ing of accuracy class C for MAVOLUX 5032C and
class B for MAVOLUX 5032B in accordance with
DIN 5032, part 7.
Additional details can be found in the DIN 5032
standard.
