I hate to tell you this but Ken is wrong, the result CANNOT be the same.
For example, if you have a yellow sphere, a red light to the left, a blue
light to the right, after rendering and converting to greyscale the result
with NOT be the same as converting the colours to grey first and then
rendering.  (As the converted lights will not react the same way with the
objects because they no longer obey colour laws of wavelength, they all have
mono-wavelengths)
