Calm down a little, admittedly they didn't lay it out...if thats the case, then from here on out, EVERYONE, stop measuring Par, because its meaningless.
So, whats meaningfull to YOU.? U going to come with fancy BS words like efficacy, efficiency, 2x56hSqar*2Nhm BS?
Explain how these numbers are meaningless, but across the board, everyone measures PAR.
If i said LUX, i see your point, but we're not.
but then again, your an advertiser, your supposed to dog out and destroy people that dont use YOUR product line or brand. I see ya.
Par or PPF is the measure of all light [photons:radiometrically] per second umol/s,
PPF/D is in a Square meter of space but the same umol/s^2.....
A single reading like you mentioned doesn't account for all photons per second of that fixture, just a narrow area where those diodes may be more powerful than say diodes on the outside that aren't measured in the "spot" reading..., so it is completely innacurate and would be also technically different for Kelvin temps as Blue waves give off more photons per/w than Red waves, so we need an accurate way to determine ALL light.....does that make any sense?
This method is used for all types of light, not just LED's.........
