Lux Lumens and Watts per square meter

[Deleted member 74205]

Homework Statement

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.

Homework Equations

None availiable

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?
