Look like its time to kick hid to the curb and jump on these deals! Don't like the initial cost, but the long term totally outweighs it. Plus I need the efficiency big time. The summer months are a PITA.

Jeezus fcking christ people. 3 pages of pointless dribble and bickering and 29 fucking posts about the OPs motivation to get to what really matters. or used to matter in this sub forum.
Cree is dropping a new 200w cob on us!
this is a topic that used to excite some people and arouse some discussion and excitement. but i guess its more interesting these days to attack each other and bad mouth all the competing diy suppliers.

I'm going to wait for the new veros in 3 k or switch the rest of the 3590's if the price drops. Decisions decisions.

Yeah Cree 200 watt cob.... Umm if that's nominal it will be a f***in beast at 75 Watts!!!!

i dunno... after playing with 300-500W cobs for the last 2 mos im not gonna get a boner over a 200W offering.. but the proof is in the pudding (and how much that pudding costs)... so we'll see what it can do. prob more excited for the new veros which we know are gonna kill on performance/$. and then hoping to get samples of the new citis by christmas

Anyone got the data skeet skeet skeets on this 200w cree yet?
Gunna need some supersize pin sinks soon

200W nominal would be more like a CLU058-3618.

I'm proud of all the people breaking the Cree vero mould. Innovation and exploring other products is very cool.
Who has compelling grow results from Citizen? Where's the badass high quality high quantity cannabis grows using these 300-500w cobs.

Haha lol yeah this is what I am trying to tell these guys we are growing weed with led with a reason high efficiency if you want to hit 1g/w then go for HPS the problem is that leds lose efficiency at higher watts, If those new leds dont give me a higher gram/watt ratio then my cxb3590 whats the point ?
Vero 29 C type looks good but they measure at 25c and high voltage going to be a hard time fitting led driver let alone for the unknown price and shipping times.

yeah thats why i asked about the data sheets,be nice to see where this bigger cob is at lower amps lumen wise

Advertising? Hell you've got people posting up a storm literally selling shit here on these forums.
On top of that if he didn't want the prices known he wouldn't have spammed up an email trying to drum up biz.....

Hi, one of the guys you were "trying to tell" here.
The point is that a CXB3590 at 56% efficiency is about 50% more efficient than the best HPS. That doesn't make a light that is only 25% more efficient pointless to build for somebody on a budget. At all.
A second point I will make is this: prove your light is 56% efficient. You got that number off a spreadsheet from some guy in a weed forum. I personally believe the spreadsheet lines up with reality, but it's not from Cree's datasheets and so far, nobody has proven it's absolute correctness.
But I can point to tentative proof that the new Veros and Citizens are outpacing CXB3590 CD bins because every person that has tested them, three so far on this forum, have found Cree lagging behind. In other words, whether you think a 50W CXB3590 is 40%, 56% or 66.66666% efficient, empirical testing by various people put it behind the next generation Bridgelux samples or currently available Citizens.
It's not a big deal, Cree is due for an update, and everybody is a winner. But there is room in this world for budget builds that are less efficient than Cree, and there is stuff available now that is more efficient for the same price. Who cares? Everything is a tradeoff between cost, ease of build, and efficiency.

including the new veros there are at least 3 chips (that we know of) that outperform the current 3590s. 4 if you count the 1818 (above 90W). and thats just actual efficiency in par per watt. if you look at par per dollar cree is generally near the bottom. they make great chips, but at what cost?

I always have grow under HPS , It is a good system that has proven it self to bad the cons are just to much heat is a big problem so you need more cooling. I tried LED years ago and it was awful (chinese) So a friend of mine told me that there are some new leds en things So I started to read stuff and things like that at the end of the day my conclusion was to compare lights just take the lm/w at the correct spectrum to have a higher g/w ratio.
Why I can't stop talking about g/w ? I am from holland and what we have learn in the past 40 years is how to maximise every squar inch that we can put ouhr hands on to get the most weight from that space, And less watt with same result as HPS is just a game changer.
So I tried the CREE CXB didnt change my setup and room I hit 1g-1.1g/w of amnesia haze with a Gavita DE, My first run with the CXB3590 I had a 1.5g/w So I started to learn more about it and how to use LED becouse its not HPS you need to work with it not against it. For example the air intake and exhaust are different in a proper LED and HPS grow room. So after that the efficiency of my grow room went 20% lower(less cooling) and my lights 40% lower not 50% becouse a Gavita DE is pretty efficient. And I hit 1.6g/w solid hard nuggs the guy from the coffeeshop that buy my stuff is also very happy because there is a difference between led and HPS weed. More compact and good bag appeal.
@CobKits
At this very moment I am paying 1.5 euro for 1 watt all in !! for the CREE CXB3590 CD at 50W and 184lm/w
And with all in I speak about drivers, passive heatsinks, holder and the frame !! I love the spread of 4 Cree chips at 50w and it fits perfect in my room. Ooh and If I order now the TNT guy is after 3 days at my door with a nice package and this is very rare in EU.

Which one? HPS or LED?

I probably haven't seen all of those comparisons, but I have seen a whole lot of incorrect comparisons. For instance, I have seen a massive Citizen COB get compared to a CXB3590 and indeed then the Citizen is more efficient, but of course that isn't a fair comparison of the technology.
It's like when people say a CXB3590 is more efficient than a CXB3070 when in reality they use identical technology. Exact same diodes, exact same fluorescent coating etc etc. It's just that the CXB3590 is almost 30% bigger and therefore needs almost 30% more power to run at the same efficacy. So a CXB3070 @ 49W (1400mA) should be compared to a CXB3590 @ 61,5W (1750mA) etc. That way you get a fair comparison of the actual efficacy of the underlying hardware. It also gives you a much better comparison of price levels since the 3590 is more expensive as well.
So Cree is not really lagging in efficiency, but they are relatively expensive at a chosen efficiency level. Which makes it cheaper to buy more of the less efficient Citizen COBs of the same size (or indeed Citizen COBs with a bigger LES) and run them a bit softer to get the same efficiency at a lower price.

But they are in the same price range.
