    I chop down in 10 days. I'll keep you informed. I personally haven't ran any DE rooms so I can't compare on that. But I want to stagger them and really get a nice spread.

    Oh btw....just seen the new Sun Systems catalog at my local shop. Thet go one called "The Beast". Lol. Its a 1000 watt double ended in the middle. One 315 cmh on either side of it. And the Double ended is dimmable down to 600 watta i believe (dont know if your spectrum gets a little wonky doing it though ) I dont really need them bit it seems The Beast fixture would or could easliy replace well over 2000 watts of old school single ended hps. So many damn lightting choices the last few years. Plasma...Induction...Cmh...LED...HID...COB T5'before just a ton that wasnt there just a few years before. Gets confusing to get the right ligjt source to a particular style and setup. Mogul socket single ended HID' s are starting to look like dinosaurs. And not worth it (falling prices of cannabis) to run them when there is a cheaper alternative.

    ditch traditional hps/mh for ceramic,, but DE i have no experience with so i cant advise either way.. ive heard good and bad on double ended hps,,however i did hear a 1k gavita de is 20%% less efficient than the 315watt lec lamps

    I been doing some research last few days. I think i got the skinny now. Using 2 315' (or one 630 lec) for every 600 to 1000 watts worth of double ended HPS is thee ultimate setup apparently. The 2 pair up together perfectly. Your lec's are for the extra blue that really bumps the quality and your double endeds for the fatness and yield. I got some ideas i wanna try out. Visiting my boys nice sized op recently got my gears turning.

    Not really. Just figured some shit out myself on them new Grow Beast fixtures (two 315 lec's and one 600 double ended hps in the middle) with a light rail....in a certain application i feel as though one could crush it with 1230 watts of combined LEC & HPS de. The key is a light rail with extension kit to 9 feet. The fixtures caught my eye in the new Sunlight Supply catalog i got at my local shop. They looked like they had potential in my eye so i googled it. And of course forum growers just dissed the lamp right off tje bat. So that REALLY got me interested. Come to find out....with my line of thinking....not only are they not bad....they are damn near perfect for a certain setup. The light rail (which i hardly recommend except for very specific applications) being the key.

    my opinion is 2 315's are better than a single 630watt fixture, you can spread them out for a larger coverage area, get it closer to canopy, heat is spread more evenly.. just my opinion tho,,im sure there are times or area's that would be better with the 630 like a 4x4 tent,, but then again for me id rather have the option of 2 hoods rather than 1

    Just found out that the Sun Systems Grow Beast fixture was designed with the popular 4x8 area or table in mind. And with a 6 foot light rail moving just a little back and forth so all canopy gets the mix of lec and hps de. Iam seriously thinking about getting the whole setup as an experiment aside from my regualr operation. The usual setup with a 4x8 area or table is 2 1000 watters (single ended) or 3 600 watters (single as well). The Grow Beast is just 1230 total...a 315 lec on each side with a 600 watt hps de in the middle (you can put a full on 1000 hps de in there but you would need to raise the fixture so high as to render the lec lamps damn near useless. ) But anyways...iam gonna try it here soon. If i can get 1800 to 2000 watt single ended yields ( 3 to 4 pounds) from 1230 watts of de and lec combined its a no brainer. And the hype is justified with lec and hps de together for state of the art cutting edge lighting. And besides...been wanting to upgrade my tester room. And this would be perfect.

    Trichs came into range quicker and this part of the plant seemed healthier overall. Chopping tomorrow! 20161217_095946.jpg

    Cob led is out of most peoples reach...just for the simple fact...we want to grow buds NOW...not dick with sourcing and building out a fancy grow light. Its definitely NOT the first choice for most growers in 2016. Thats my reason anyways. Sounds like a big pain in the ass to be honest. I will wait until they are commercially available at a price i can afford. I started to delve into the whole cob thing and quickly (smart too) backed off. A large majority of growers are thinking like this too. We all know its the mostest and bestest light but ya gotta find the info...source the parts...and build the goddamn thing yourself. Its a whole another geeky hobby if you ask me. And i already got one of those...growing dope.

    Here's the flaw in your logic;

    2016 IS OVER.

    Any of a number of different sources are selling COB LED right here on RIU in kit form, all you do is assemble the parts, and in so doing save a bundle. Having to source all your own shit is the part that's sooooo 2016.

    Responding to a different part of your point, I outsourced the building of my lights. It worked for me, in part because I made a sizeable order worth someone's time to assemble and deliver.

    I'm glad I did it because I learned a lot about the process and the lights have made a very significant difference in the quantity AND the quality of the resulting product.

    So here's your challenge; I've pulled 2lbs from a 4x6' trellis, with only 900W of COB LED.

    To match density of production, you'll need 2.67lb from your 4x8' table, to match Watts/sq ft you'll need 1200W. I think these are very attainable numbers.

    Except that I did it with only 6 sq ft of floor space.

    Can you point to any of these quality builds because I too don't have the time to delve into another hobby and learning a new skill set at this very time. But id love to supplement my CMHs and DEs with some LED and have the ultimate room and spectrum.

    Iam hip. What and where are these kits? Tools you need if any? Id love to try em out...but iam not getting all involved in schematics and diy buildouts. Dont get me wrong...i like to see less of an electric bill just like the next grower....but i dipped my toe into the forum cob world...for just long enough to get it out and run away. All this talk about bins and heat sinks and percentages and...good god man. The price of dope is falling but i still make good money. Iam fine with double ended and lec lamps for now. Until i see these fancy cobs in the store for 500 or less...i will let yall build away. I dont have the time nor the inclination to build a frikin grow light. I dont care how bad ass they are. I mean...really...are they THAT much better than a couple de 's and a couple lec's you can buy anywhere and slap them up and be growing in hours? I will wait till the stores stock them like all the other lamps.

    Yep same here. I work part time and go to school for my doctorate and masters simultaneously. Growing is paying my 210k in school loans so that I can live a legal and frugal life when I get out.

    Ok...heres my challenge..What kit or kits do i need to replace 4 of my Gavita 6/750 flex lamps that i can pull 24 zips of Blue Dream off of the 600 setting on each lamp (and thats a lazy same as it ever was grow). Whats the real world wattage...and how much ac do i need to keep ky canopy around 80 degrees? See what iam saying tty? This is the majority of growers line of thinking. They dont want to get into all that jazz you guys talk in the cob threads. Just simple and to the point. Because everything else just goes over thier heads. It does mine. Seems you have to want to or have a real passion to get into the diy cob world. Most growers could care less and just want the lamp the grows the best and most buds for the least amount of electric bill doing it. All them charts and links and part numbers and percentages of efficiency and all of it....just eludes me.

    Have you tried anything else besides gavita? I'm new to DEs and am ready to supplement my LEC room with some. I like to pay the up front cost and just get the best there is. Buds pay for lights in 10 weeks lol. I have friends that only use phantoms.

    Thank you. I'll of course do some of my own research but nothing helps like personal reviews and experience.

    I too have been looking at cobs and learningthe configurations but have been reluctant to order components
    i was going to grab a 315 but have herd it may not be enough light for my 4x4
    and i have herd a 630 (2-315's) would cause to much heat and too much light in a 4x4

    So now im wondering what's my best bet
    im in Canada and having difficulty finding sources for either within canada cob and cmh
