I'm doing my own technical research into the relative efficiencies of LED vs. fluorescent bulb technology. I've found a data sheet from Sylvania that details the spectral power distribution, but I'm at a loss as to how to interpret the data presented.

For example, looking at the graph for the regular warm white bulb, I approximate that at both 450nm and 660nm, the data is .0033. Say I have a T8 bulb, with an average of 3000lumens with a power input of 40W. Does that data allow me to calculate the number of watts utilized (of the 40W input) to emit spectral lines at each wavelength?
