Water cooling is an interesting idea. It would certainly be nice for driving leds at their max rated amperage. I'm not an ace welder or I might build myself one. I'd be concerned about leaks. When charged with coolant it would probably be fairly heavy as well. It would be doable. I'd try using a automotive transmission cooler as a radiator.I'd have them at 500mA , spacing not sure. Enough to where they barely blend into each other. Do 60 degree lenses for whites. 80 degree for 660. Figure out some sort of liquid cooling like with show car sound systems and turbo intercoolers.
I reckon you missed the indagro post.....I am flowering some test moms with exactly your dimensions on 2 4x4 tables each with a 420 light.....840 watts......pontoons would add a few watts and movers a few more......still would come in under 1000......Everyone(except kool) obviously missed the question
I didn't miss it, it didn't go into detail like you just did. Not to mention your counter productive comment to start things off made just 30 seconds after I posted the thread really didn't make me want to acknowledge your second attempt to chime in.I reckon you missed the indagro post.....I am flowering some test moms with exactly your dimensions on 2 4x4 tables each with a 420 light.....840 watts......pontoons would add a few watts and movers a few more......still would come in under 1000......
so under 2000w money no object for 4x8 no shit would be 4 static proPAR420's with 4 pontoons.......that would be.like 1830 watts but the pontoons only run at lights on/off so really less....that would be like 65 hundie too lol money being no concern and all.
You my friend have put some good thought into this. All great choices.For a 4x8 and money is NO option hmmmmm.............my dream setup under 2000watts
http://www.plasma-i.com/ecoplasma.htm 2 900w sulfur plasma panels !! lol ... their awesome though
or
2 660w apache tech 3/2 wr panels
or
4 cycloptics tech 315w philips elite agro bulb/vert reflector kits http://www.cycloptics.com/ god I love this thing, too much $$ though/dedicated 220v line
or
Illumitex unreleased/upgraded neosol panels..............as many as it takes to cover the area, when are they releasing their new gear anyways tags????
or
3 helispectra l4a panels!!! yes and we get to play sun gods with dials/software http://www.heliospectra.com/products-solutions/heliospectra-l4a-series-1 and whatever there releasing soon would interest me as well...........best quality emitters for the respected nms , second to none in build quality....but $7500 a piece
etc.
How many of each and in what configuration...how many watts total??XM-L2s, Oslon 660nm, XP-E2 630 all running at 350mA on copper mcpcb's
With roughly 50% total efficiency, just a dream though!

EDIT:
I wonder what the chips in those heliospecs are?
Brother Tags You Actually Asked 2 Questions But I Will Answer The 1 You Want.But First I Belive We Led Users Has To Have A Different Mindset When It Comes To Watts Per Square Foot.I Know EH Has Been Drilling It Into My Head That More Watts Are A Waste Of Electricty When It Comes To Leds vs The HID Mindset.In My Last Grow I Ran 2 Area-51 Sgs's(155 Watts Per Light) In A 35x54 Tent And Hit.98 GPW. With 1 Plant Producing 70 Grams While The RockStar Came In At 234.5 Grams.You See I Like To Do More With Less Or Make My Grow As Efficient As Possiable And I Now Know That I Can Produce 1Lb Of Awsome Dense Buds Using Only 310 Watts Of Power.In Short My Brother I Already Have My Dream Setup But Of COARSE I Will Always Be Searching For That Holy Grail Spectrum.Now My 4x8 Setup Would Include 6 Area-51's Newist Light With 6 Scrogged Plants In My DIY WaterFarm With Attached Screens 24x32.
So my question for everyone is...
With the goal of less or equal to 2000w...What would your dream 4x8 light setup be, if what ever you chose was totally free upfront, but still have to pay to run them? As many of what ever that you need to truly preform as well for the whole 4x8. What company(s)/tech/DIY design would put your faith in?
Also could I spend some money on solar panels as well? That way I could charge with POCO supply or with the sun, then I wouldn't have to pay for anything?I think phase one of my setup would be the DC power supply system, I would buy a few ultra capacitors or battery's and have them charging at the maximum 2000 watt usage when ever the lights are not in use. Then DC power supply system would feed the 2000 watts from POCO into the lighting system while adding peak boosts of up to 10,000 watts from the super capacitors during the daylight times, of course you would have control on how much extra power, you could just double the 2000 Watts to 4000 or just ad as much or as little as you want, while never going over the 2000 watt supply from the POCO.
The lights would properly be Bridgelux COBS of 2700K, 3500K and 5000K color temps.
EDIT: I think you would boost the power when you know the leaves are not in photo protected mode and then switch back to POCO supply when they are. That way you are not wasting the extra light power by just making heat but still supplying the right amount for proper veg.
