I am working hard to start production of the panels. 
I've tried to keep the price as low as possible, originally thought around the $560 mark but opted for the slightly more expensive red led in the panel but I'm hopeful that it's still gonna be good value at $590 and my veg model will be $585 both units consuming 260-270watts each. I've also opted for the 60 degree lens and recommend 15 inches above the canopy for a 3 x 3 grow area. I could have used 90 degree lens but this would have meant having the light closer to the plants for more penetration however doing it this way means the heat from the side vents is kept further away from the plants and thus extracted out the top of a grow tent much easier, for those who have hot days in the Summer I'm hoping this makes sense as temps above 28-29C cuts production by up to 90%.
Thank you very much for your advise, however I don't think we are talking about the same model ? Mine has 150 led's not 144, I think I know the one you are talking about but it is a different ball game altogether. I understand where you are coming from though regarding the inverse square law of light and it also depends on how much light you can squeeze into a given angle, remember ,we are talking about lenses here not reflectors. I will try to find the link for a Cree paper regarding reflectors and will post it on here IF I can find it
Scroll down to page 6.http://www.cree.com/products/pdf/LED_Luminaire_Design_Guide.pdf This is on a normal 90 Degree using a reflector on a diode compared to any other light source (in this case a CFL) However, use a dedicated lens to focus rather than reflect, and the losses are negligible.In this example they are using four led's in a fixture using the fixture to reflect on a given footprint and although it is a bad comparison for LED's they still win on a loss of lumens basis, this was done without the obvious advantage of the now available lenses. I will take your recommendations on board though. Peace 
Yep I was going to go down that route but decided against it. If I may, lets just say that we have a fixture that is using 300watts , 100 for veg led's and 200 for flower. The advantage is of course that you only need 1 light but you're still only using 200w for flower the way the current led's are designed. In addition I think most growers agree that LED's are great for veg but all the HPS enthusiasts say the LED's are rubbish for flowering ?
This isnt entirely accurate. To use your 300w led example, if 100 are "on" with the veg mode switched and 200 "on" with flowering mode switched, you are forgetting that with both switches on you get all 300 "on" but that is only if you have 3 modes: veg, flower, and full spectrum. please correct me if im wrong, but what I think you are meaning to say is that they only get 200w of leds that fall in the "ideal" flowering spectrums.

so were talking about the lens angle that is on the chip or are you adding additional reflectors like the x-lens ...? Both, you will still have to be careful the penetration power of both the whites and blues. Sure would help if you gave some more information on the look / style and model etc of the led you are getting manufactured. Can you get any pictures?
"
not all HPS users think they are rubbish for flower, but most on rollitup do(lol) . I have converted many myself. And with the right LEDs and training techniques I believe led is superior in quality and yield. HID is old history in the twentieth century
You are correct, I should have put it that way
5 per month to different friends addresses ?
however, hps would benefit from adding 660 which can gotten from leds & ho t5s
and current tech large panels do create a lot of btus
