Lux Lumens and Watts per square meter!

  1. Apr 2, 2007 #1
    1. The problem statement, all variables and given/known data
    I am looking for a conversion factor that will ultimately get me from units of lux (illumination) which is a weighted scale of light intensity, to watts per square meter, which is not weighted.

    2. Relevant equations
    None availiable

    3. The attempt at a solution
    I am informed that the conversion is different for each wavelength of light, so there may be a conversion table with a list of wavelengths?
