These data are not likely useful to most people, but to the people that they are useful, they should be quite useful. For example, to convert lumen to umol/s from a lamp or LED digitized SPD, or to calculate the lux to PPF conversion factor of the lamp or LED using its digitized SPD.
We're sharing for the sake of sharing all our work we're able. This isn't anything unique, but it is likely the only place to find these data all in one place, in a easy to use manner.
This spreadsheet we made includes the following data sets by 1 nm step size, from 390 to 830 nm:
a) CIE luminous efficiency functions (2 degree)
b) CIE luminous efficiency functions (2 degree) as %
c) Photopic curve from the 2006 CIE LE functions
