I don't know if these charts have been posted before. I've read a good number of LED and Inda-Gro threads and I don't recall ever running across links to this information. So I thought it might help out those trying to decide on what lighting type will work best for their application.
These charts give you an idea of what different lights are producing for various PAR values and how efficient they are at it. The charts include what each produces in the Vegetative (400-520), Carotenoid (520-610) and Flower (610-700) regions.
Some Highlights, highest scores in blue.
PPF (uMol/S) @ V (400-520) C (520-610) F (610-700)
1000w HPS - 72 - 848 - 587 - (1.37 uMol/S per watt)
600w HPS - 47 - 560 - 387 - (1.51 uMol/S per watt)
650w LED - 258 - 91 - 821 - (1.80 uMol/S per watt)
(Lumigrow 650w)
460w Induction - 174 - 122 - 303 - (1.30 uMol/S per watt)
(Inda-Gro w/Pontoon)
LED is king.
Inda-gro's 420 with pontoon does outperform a 600w HPS if you tally just the (400-520) & (610-700) ranges 477 to 434 uMol/S in those ranges.
Notice how much the 650w LED trumps a 1000w HPS in the important (400-520) & (610-700) ranges
The LED beats the 1000w by 186 uMol/S at (400-520) and by 234 uMol/S at (610-700)
One thing to keep in mind when you see the PAR coverage in a 4x4 grid using 600w & 1000w HPS... more than 1/2 of those #'s are being produced in the least efficient (520-610) range.
The 1000w Produces 848 in (520-610) and 659 combined for (400-520)(610-700)
The 600w Produces 560 in (520-610) and 434 combined for (400-520)(610-700)
