I have realized with these Gen 7 Vero29Cs.citizen and bridgelux are a generation ahead of cree, and citi is about to be 2 gens ahead in january

Awesome, well for that price ill certainly look into them. ill start working on a solution for those then for now, and maybe decide later, but those sound really nice for that price im just about sold!Me to, but he's order min.
http://www.meanwell.com/webapp/product/search.aspx?prod=HLG-320H-Cim not seeing that, where are you getting that number?
also i agree with 4x 1825 smoke 2x3618s. you really need to be well up above 200W before 3618s start paying off
they kind of already are. you can get the same performance out of cobs that cost 1/2-2/3 as much as that. same setup but there are a lot more options on the market since growmau5 made his most excellent video series back theni dont want any new tech to emerge that will render my cxb3590s archaic lol.
what are the options, the vero 29s/ citizens? pardon my ignorance. im trying to learn as much as possiblethey kind of already are. you can get the same performance out of cobs that cost 1/2-2/3 as much as that. same setup but there are a lot more options on the market since growmau5 made his most excellent video series back then
I'm talking at least 200-250w and over. Where is the sweet spot wattage wise and what drivers are good matches for 2-3 maybe 3618s on a circuit and/or separate drivers and circuits for each in order to accomplish ?3618s beat 1825s by just a few lumens per watt at 150W, and then they pull away above that. up to 150W im going to recommend an 1825 ever time
I have lower prices on all that and you would only need 3 of our ZPE 400 watt drivers, 3 will run 33 cobs at 1050ma,hello everyone, this is my first post here but i'm an ICmag regular. getting quotes together for my LED build but wanted to have some of the more knowledgeable LED guys take a look to make sure i've done my numbers right.
looking to run 32 cree cxb3590's off (4) HLG 320H-C1050B. By my calculations i've concluded that each one can run 8 @ ~40W for a total of 1260W at the wall and these should be smack dab in the sweet spot of efficiency.
ran into some sudden expenses so at the moment im looking to build my framework and heatsinks first and then place my order through alibaba for the LED gear.
another reason for doing the framework first is that in the month or so between building the framing and ordering the LED's etc i dont want any new tech to emerge that will render my cxb3590s archaic lol. i don't know much of any of the other COBs, as my main source of info is growmau5's videos on youtube.
here is my quote list in case anyone wants current prices from kingbrite:
32 CXB3590 3500K top bin $33 each/$1056 total
32 ideal solder-less COB holders $2.80 each/$89.60 total
32 reflector adapters 1$ each/ $32 total
32 reflectors $.80 each/$25.60 total
4 HLG 320H-C1050B $86 each/$344 total
shipping $77
bank transfer or paypal $20/ 4.5% ~$75
Total $1644-$1697
For the heatsinks i'm looking at ( 36" X 5.886" $501.12
Framework 6061 1" angle aluminum 1/8" thick, 28' total $33.42
~$2231.54..........WOW lol
how we lookin' so far? still need little stuff like the wire, wago connectors, shrink wrap etc...
Good to know. What's the link to your site?I have lower prices on all that and you would only need 3 of our ZPE 400 watt drivers, 3 will run 33 cobs at 1050ma,

Imagine how I feel!Damn, so my 4 cxb 3590's sitting in a box awaiting my final light bar build are nearly obsolete? Lol, I've only been running the bars I've built for. 6 1/2 - 7 months! This is what I get for slacking on my diy current cob tech knowledge. That and no internet access for nearly a month doesn't help either.
Ive tried running my 1825s both with hlg185-48A (maxing voltage and current, 1 driver per cob) and using hlg240c2100 (dimmer lead open and 2 cobs in series) and they gave a very similar amount of light even though the first setup was about 400 watts and the 2nd was 250w. Hlg240 is the way to go on this one IMOI am going to run Hlg-240h-2100b and 2x clu1825 per driver.
I just need to confirm these will be wired to the cobs in series correct?
I don't have my potentiometer yet so can I still fire it up?
Other than that I'm basically assembled and ready to go.
I have CXAs and CXBs and they might be generations behind, but I can kill 1gpw all day.Damn, so my 4 cxb 3590's sitting in a box awaiting my final light bar build are nearly obsolete?

I'd say you're well past it.Good to know! I know that I can't really go wrong with any of them but I just wanna give LEDs a fair shot this time. Right now I'm thinking 24 1818s over a 4x8 driven by 1.4 amp drivers(not sure which wattage yet) hoping the new 480s come out soon
Any idea at what point the law of diminished returns begins? By my calculations I'm around 1335 ppfd with this setup
My numbers are a bit high because my shit tent is less than 4x8 and my home made flood table is even less than that. I'm at about 28sq ft of growing space on my table.I'd say you're well past it.
after shipping and paypal fees im right there with jerry on priceafter doing a bunch of research of the last few days now I'm second guessing the cxb's, looks like I can do the 1818s for cheaper and get the same or near performance, 1825s for the same price and get more out of them, or vero 29s and save some cash. the savings could pay for my heatsinks or something else. I'm not trying to skimp but the name of the game is efficiency and its not very efficient to spend extra money to get the same thing. I'm trying to cover a 4x8 tent but I wanna blast as much light as the kids can use. any input is appreciated at this point.
