No, you're mistaken
The numbers I posted are empirical measurements taken with a Apogee ppfd meter and are not the theoretical gross output sphere measurements you may be referring to.
Nonetheless, lumens/watt is not the correct measurement to quantify useful light output for growing plants, ppfd is the measurement of interest.
These are taken from cocoforcannabis.com, Migro also posts independent light measurements with similar results.

Sorry man, ppfd is not total output of a light source, even though you wish it to be.
LM is total light output measurement as you cannot test ppfd and know what total output this light makes, only how much falls on 1 spot, which is not how to measure total light output.
You say it is or it's not important is your opinion and your entitled to it, but it's not science, don't mix the two.
"theoretical gross output sphere measurements you may be referring to."
So all those companies that measure light in spheres are just fools you say... Interesting.
301H Evo on Samsung site shows 40LM for each 0.2w diode, Samsung are idiots too ?
Right...
Understand very simple thing, LM and PAR both represent total wavelengths at the growing spectrum, PAR just narrows that spectrum some more because of new conclusions but still not conclusive.
Still, LM is the only way to measure total light output of a light source.
