Well, if You would like to calculate exactly You have to take into consederation the light source, because photons are related to the spectrum available for the cloroplasts of the plants. If the wavelenght of Your light source is between 400 and 700nm, You can calculate roughly in the following way:

1 µMol (photons)s-1m-2 = 56 +/- 3 lux

the unit µE m-2s-1 is used also as an equivalent to µMol
