If you are a commercial indoor grower, taking advantage of a big, broad range - say 100 to 1000 square feet, which company and model of LED are you opting to go with this year, 2013?

For large commercial greenhouse applications the move towards a hybridization is afoot. You may find these of papers of interest in that it describes the crop comparisons of Intracanopy LED towers as a supplement to overhead HPS systems
http://horttech.ashspublications.org/content/23/1/93.abstract
You may also wish to read another recent paper that compares grapes crop quality, phenolic, flavonoid, anthocyanin, tannins, and yields in a double blind test between sunlight only and those crops that had supplemental lighting systems installed in addition to sunlit trellis systems had significantly improved grape quality and yields.
http://horttech.ashspublications.org/content/23/1/93.abstract
With the rising cost of utility power there is little doubt that the traditional methods of using high wattage HID lamps to cover large areas of greenhouse crops must be improved upon. Philips acknowledges this and proposes the hybridization of their 1000 watt dual ended HPS lamps to be used in conjunction with their 8ft long 130 watt Lumiled strips ran in horizontal rows behind the plants.

Not surprisingly Inda-Gro has approached this from a different perspective. At about 2:00 minutes into the video they demonstrate their vertical daylight harvester that will operate on a vertical light rail. From what I've been told this approach should cut the traditional ~15w/sqft to under 5w/sqft while improving crop production. Let the fun begin!

hyroot, thanks for taking the time and for the leads. Inda-Gro shined a light on a personal problem of mine that I'm embarrassed about: ignorance with a bit of racism. My fear of non-American lighting (LED>induction) lead me away from studying Inda-Gro aside from reading their promotional leaflet, assuming it a product of the Indian subcontinent. Time for some introspection and for that, thanks.
clorisluo, thank you for your reply to my query. Should you time be as valuable as mine, I appreciate it.
chazbolin, I truly appreciate the links. I've read the Philips PDF and the 2 abstracts. I'm debating coughing up $20USD for the two papers. OK, you're going to find this hard to believe but I had this dream last month. I was in a greenhouse and several tall Cannabis trees in Air-pots were in a circle and each was individually rotating about its own center. A song from Tchaikovsky's "Nutcracker Suite" was playing. Hanging down in the center on this ring of enormous rotating Cannabis trees was a Hydro Grow 420x-PRO LED Grow Light, the one's shaped like a hanging bug strip and meant for vertical gardening. This dream was really hallucinogenic. Aside from the fraud problems plaguing Hydro Grow in the waking world, it actually wasn't a bad idea. It was a trippy dream. That's what I get for being 50 and having taken acid all through high school and college. Oh well. Actually, you have your mind wrapped around a good idea there. I have a double monitor and it's plastered with these colored Cartesian maps of Relative Absorption vs. Wavelength for most all those non-polar alkaloids you have in your second paragraph. If I buy just one paper, it will be the 2nd one, the one who's title starts: "Comparison of Intracanopy Light-emitting Diode Towers and HPS . . ."
If you believe me about my dream, chazbolin, I don't know what that says about the both of us.
Again, thanks everyone. This has been majorly helpful. Being a displaced Oregonian in NY with Oregon's HB 3371 looming, I have but a year to pull this together. As such, I'm reading this daily so should anyone else have some other ideas, toss them my way and I promise not to bore y'all with my psychology or dreams.

chazbolin, the second abstract hyperlink is a duplicate of the first hyperlink. I purchased it. I'm not sure which one's missing, but I bought the one authored by Gomez, Morrow, et. al. entitled: "Comparison of Intracanopy Light Emitting Diode Towers and Overhead HPS Lamps for Supplemental lighting of Greenhouse-grown Tomatoes". I don't know which of the two articles is missing. Sorry to bug you but can I trouble you for a second hyperlink to a second abstract?

Is this it: "Canopy Light Effects in Multiple Training Systems on Yield, Soluble Solids, Acidity, Phenol and Flavonoid Concentration of ‘Frontenac’ Grapes"

Hiya ST! Thanks for sharing that dream. I kind of caught the flavor where I saw it in my own trippy sorta looking up at the cannabis canopy with the NY Philharmonic busting out the Nutcracker Suite but the Wicked Witch of the West was buzzing the canopy while her pretty's hovered under a cloner only occasionally peaking out to see if the coast was clear. When the timing was right the lion jumped on the vertical daylight harvester and rode it to the top where he intercepted the WW and lived to save the crop. Crazy where that took me dude and to think its been ten years since I last did shrooms.
Sorry about the double link earlier. You are correct that the article you cited is what I meant to post.
