Hey Frank. This is a really nice garden you're putting up. It's fun to watch and I'm looking forward to seeing your results. I think you're on the right track by adding the light rail as that should help a lot in terms of evening out distribution.
I have been seeing you reference the PAR output of the Inda-Gro lights and I wanted to point out to get the 200uMole output you were told during a phone conversation you had with Inda-Gro would have been their response to a question regarding the average uMole value from a stationary mounted 420 series light over the recommended area of coverage (5 x 5) during the vegetative phase at the recommended 36" lamp:canopy spacing. That 200uMole is in fact the average reading over the entire 5 x 5 area. You'll see in most journals that the veg cycles do quite nicely even at the outside edges on a 5 x 5 with that recommended 36" lamp to canopy spacing. Mounting the 420 series on light rails will also enhance the area of coverage. Had you asked the values at a median mounting height (18" lamp:canopy spacing) it would have been stated at an average of 600uMoles over a 1.1Msq area (due to the aspect ratio of the fixture being longer than wider).
To graphically illustrate this point here is an on line gallery that shows a 6 x 10 room where 2 of the 420 series lights have been installed. As an aside I think it's great you're using Ed Rosenthal's Marijuana Growers Handbook as a reference for your garden. Check out all the images in this gallery and you'll see Uncle Ed, who BTW runs the 420's, talking shop with Jeo in this very garden as well as other images that show lamp:canopy spacing on the broccoli at over 5 feet and a Day 34 uMole measurement at 12" reading over 1160uMoles.

On the lower wattage 100 watt lamp, like the one PSUAGRO has been using, we can see an 852 uMole reading taken at what looks to be maybe 8" from the lamp. What's worth noting here in this gallery is that you'll see the egg plant is thriving in all phases of it's veg-flower growth on just a single lamp that has been running for over 2 years without replacement.

FYI: If you return your overpriced lights to IndaGro, even 100% unopened, they will still charge you a 25% return fee. So the best thing to do is to avoid buying any IndaGro lights at all!
The Inda-Gro return policy, up until around 6 months ago, was to fully refund the purchase if the product was returned undamaged in the original packaging within 30 days of purchase. In over three years they had taken back maybe 3 lights under this policy. The reason for the 25% restocking charges being implemented to returns received within 30 days stems from what has been within the last 6 months, an increasing campaign of sorts whereby, what may have been competitors, would order product and return it within the 30 days, many times in unopened boxes and expect to be given the full refund which they were given upon return of the merchandise. This created increasing merchant credit card and shipping charges that Inda-Gro had to bear and it also increased the likelihood that products would be damaged in transit and become unsaleable. Again up until 6 months ago it was not even an issue but with a recent uptick in this type of 'same day' return actiivity it created an increase in cases where not only would Inda-Gro be out the charges they had credited on the return but the fixture would be a loss as well.
What finally tipped the scale and caused the restock charge to be implemented was when a new dealer got set up in Ohio who on their first order purchased 3 of the 420's and while the order was en route canceled it so that Inda-Gro would get stuck with the shipping charges. To make matters worse this new dealer simultaneously lodged a complaint with their credit card company that it was an unauthorized charge. The complaint lacked merit since Inda-Gro refunds returns on the same day they receive the merchandise back and had received written authorization for the original purchase. The dealer was subsequently dropped from Inda-Gro but they soon went on to carry another induction line which is, from what I was told, using two lamps, one for veg and one for flower which have been patented for indoor gardening, are manufactured locally and provides them with what has been described as 'greater margins'. Probably this is all just a coincidence in that this other manufacturer was only discovered while their first Inda-Gro order was being shipped to them.
The 25% restock is an unfortunate result of those types of ridiculous black op tactics. To those that would wish to change an order however that 25% restock fee is offered as a credit to another purchase or may be waived entirely on a case by case basis and at their sole discretion.
I didn't mean to hijack your thread and I trust that no one reading this post would construe that I'm implying Inda-Gro lamps outperform anyone's lamps of choice and certainly not the lamps you have chosen to use in your garden. As you, and most of the experienced growers here know, uMole readings are not weighted to either red or blue. I can get a 2000uMole reading with all blue diodes so the PAR intensity measured by a quantum (PAR) meter means nothing in terms of whose got more 'brake horsepower' in an overall comparison of lights. I believe, no matter what the journals/forums post up, it'll always be a personal preference as to the lights you choose to use much like the ongoing soil vs hydro debates.
In your case you are doing a bang up job with all the high end equipment you've chosen for what I hope will be a bountiful harvest. Keep up the great work and consider me subbed.
