Kind of an ignorant knowledge base, but OK. Ignore perfectly effective technology....I know enough to never buy one

That is what its about as long as your happy with the results life is good.It makes more sense to setup shop with DE right now. This circular argument doesn't need to keep going on. DIY led is more for hobbyists and research and development. But seriously, if you looked in one of my tents, you'd be shocked at just how bright these things really are. I've actually burned holes in my floor at low setting, the same way you'd burn ants with a magnifying glass if you're at point blank. It's easy to believe the lumen values and calculated efficiency when you see how bright they are in person, or what they can produce.
Keep in mind, I'm not a salesman (i'm the one that gives away everyone's recipes)... I've used HPS all my life, experiented with COBs to see what they were all about (i ignored all the other LED shit for over 10 years.), and have been very happy with teh results. Would have I saved money using HPS? Probably.
I don't think anyone cares if you're against led or not. LED is a fools game. Think about it... In order to get the 50% efficient lamp, you have to pay BIG... but consumers think "i want to grow with LED to have results like that guy with the DIY lamp", and look for the cheapest one they can find... because they think somehow they can game the system. This is the mentality these company prey on. They always end up buying the cheapest one, don't get the results of the 50% efficient lamp, and conclude "led's can't flower" or "leds can't penetrate".That is what its about as long as your happy with the results life is good.
People tend to think i am totally against LED tech or cobs i am far from it
If I had just a few lights and heat was an issue maybe. But I have great systems that kill it and I wouldn't jeopardize perfectly fine setups for technology that I have heard nothing but bad things about from other larger scale growers. Like I said before, might work ok on a small scale but there is a reason everyone isn't switching over to them. When DE hit the market, everyone switched almost instantly. Led has been around for a while and yet I don't see warehouses full of them. There is not 1 person out there that will say DE isn't as good as regular hps, but there are many who say LED doesnt compare to hps.Kind of an ignorant knowledge base, but OK.

COB tech has only been around for the last couple years. It's only been used for growing pot by small scale enthusiasts for about a year or so now. This is fairly cutting edge lighting technology that wasn't even originally intended for horticulture use, but just happens to be very well suited for it. Much like HPS lamps in days of old.If I had just a few lights and heat was an issue maybe.

You know what you guys have convinced me, what is the best LED on the market that will even compare to my DE HPS? I will do a small scale test to see. I bring all my runs to sequoia labs so I will be able to see for sure.
You can get slightly better actually. The 36v CXB3590 @700ma is about 58% efficient.The best LED on the market. The top bin 3000k 80cri CB bin driven at 700mA (72V version)
http://www.cree.com/~/media/Files/Cree/LED Components and Modules/XLamp/Data and Binning/ds CXB3590.pdf
It boasts a luminous efficacy of source of 168lm/W at 700mA, and an efficiency of 51.67%
Driving lower would make it run even more efficient, but be more cost prohibitive as you'd need more cobs to get the same output.
But the 36V has twice as many strings of half the length as the 72V version. Running the 36V at 700mA is underdriving significantly more, so the $/PARW is much higher.You can get slightly better actually. The 36v CXB3590 @700ma is about 58% efficient.
3 x 3 ???? or being rectangular built 3 x 4 ??? have it a 5 x 5 area i am sure outter plants would stretch just guessingAnd what foot print are these lights suppose to be put over?
In the words of SDS, that herb on your dest right now must be very dank. You could run 10 in series on the soon to be released HLG-240H-C700[ ] series.But the 36V has twice as many strings of half the length as the 72V version. Running the 36V at 700V is underdriving significantly more, so the $/PARW is about the same.
So you have to use almost twice as many as DE. I use a 4x4 foot print but a lot of people go 5x5 with DE. At 5x5 thats almost twice as many lights needed3 x 3 ????
I figure 250w to cover a 2x4 or 2.5x5 space give or take.Yea what footprint are the cobs suppose to be put over. I run my ac/de over 4x4 but I know a lot of people wh run their DE over 5x5
