Think man. At what distance is the the light cone a meter across? That is one good distance to calculate flux at. But, I am interested in another distance. Is that OK, with you?If you don't mind me asking, what is the point of calculating it at a distance if you are not going to be using it at such a distance?
How high is my usual plant? And I guarantee there is more to this plant than the canopy. So, I know that you are absolutely using yours at 3 feet, as well.
3 feet is at the bottom of a 4 footer where those Big, do not defoliate Leaves are.
So, what makes you think you only "use" LED at the top of the canopy, hmmmm?
