I'm running low on space and $ for testing LEDs. But I really want to put a Fluence VyprX vs PLC cxp250.
There is a bit of a wattage & price difference, but I think it would be fun to do and see.
Are you accepting sponsors? Lets market the canopy. Starting with a link for sales on all your YouTube noob vids. :bigjoint:

LED, HPS, plasma, floro, the sun...surface mount, COB, LOB, single die, multi-die, bond wires or not; source type doesn't matter. The plants don't care where the photons came from. As long as they are provided it's all good. And for all intents and purposes(leave the reductio ad absurdum at home, or at least test it if you're going to bring up a single monochromatic setup like yellow or green) ...really don't care what color/nm they are either.
Whatever is providing the most light, is likely to be the most successful.

What is the PPF?, is the most important thing to know about your fixture. After that it's about using/implanting it correctly. Most of the time listening to the manufacture is where to start.
No matter the efficiency or power of your source, the goal as a grower is to supply a target PPF per area. Whatever it takes of certain techs/brands to get to that figure...is whatever it takes.

The "how to power" thread might be more appropriate for this next part....
We could even begin to forget about COB's or any specific type of led and start referring to them by the chip count and drive current of each chip. This would take all the variables of packages out and explain exactly what is going on.

Lets compare all these when ran at ~75w(+/- 2w)...

cxb3070
= 132 die...11 strings of 12... 2.1a÷11= 190ma per die
clu48 1212 = 144 die...12 strings of 12...1.95a÷12= 163ma per die
vero29 <V2 = 156 die...12 strings of 13...1.9a÷12= 158ma per die
cxb3590 = 168 die...14 strings of 12(36v), or 7 strings of 24(72v)...2.1a÷14= 150ma per die
clu48 1812 = 216 die...12 strings of 18...1.35a÷12= 113ma per die
clu48 1818 = 324 die...18 strings of 18...1.4a÷18= 77ma per die
clu58 1825 = 450 die...25 strings of 18...1.4a÷25= 56ma per die
clu58 3618 = 648 die ...18 strings of 36... 0.7a÷18= 39ma per die

Too lazy to dig up common nichia and new bridgelux die count's and arrangements...but you guys get the point.
The more strings, the more the input current gets divided up and thus lower/more efficient currents per chip, assuming die count is the same.

Density is intensity and penetration...not current or power per die.

Well put. I've said the same thing about die count a few times now, but not explained nearly as thoroughly.

Citizen's pricing scales almost exactly with number of dies, and I see no logical reason efficiency wouldn't as well. Same leds, same phosphor, the only thing that varies is the power each die runs at. There will be subtle temperature differences because of package/LES size and thermal resistance, but subtle is the key word there.

And to really make the point, here's an 1818. It's hypnotizing....

Can we assume that the performance differences between dies from various mfgs are smaller than the differences in current per die ?

My favorite word: density. Correctly used of course.......:)

Pretty cool
Reminds me of something on Fremont....I absolutely detest Vegas, but i do have a newfound appreciation for the lights, which I didn't back then :)

We can't assume it cause some are much better, and why some companies protect their die/processes like fort knox vs others that license them. But we can ignore that for now. Specially as we only have a choice at the end packages.
Just the principal of lower current yielding high output per watt is the premise all should understand(and most do on a macro level...but its starts on the micro/chip level), and showing it basic like that is pretty clear.

If only people, and more importantly companies understood it.
I just laugh when I hear penetration. Partly out of immaturity...but mostly to keep from crying for the industry.

Sounds very interesting. Are you able to elaborate on these cobs like what's male/ female etc. The best I can buy for the money. There seems to be very over complicated info on the Web!

Measured the centre of my cobs (cxb3590) at over 100c today. Is that normal for the centre of the cob with an rz diffuser? Maybe I better take the diffuser off

I'm having deja vu with Tags active on posting great info again..............I thought gg is on vaca?:wink:...that ad/stripe would piss me off too

short paths between dies also helps it as a package, I want to see a top group/bin non-phosphor coated cob on the market as well

This place is as shady!! Not sure anyone here followed my kind k5 experience thread but kind contacted riu and it was deleted. Is this how they make money? I know kind probably paid them off cause they paid me off to keep quiet. Have a check sitting in my truck to prove it. My refund came from growers house but when I questioned them it only took a couple days to see some money.

A link to a quick rundown.

@Smee23 are you willing to build your own from kit form or separate parts sourced by yourself? Or would you prefer a pre built unit? You should watch Growmau5 's vids on youtube and check out his led basic vids as well as his grows, you will be able to decide if you want to build your own then. Pre built or kit, either will do you proud.
Here is one example of a kit that would fit your 60x60 space and budget and out perform what you have been using.
http://cutter.com.au/proddetail.php?prod=cut2900
I think its Mark from @welight on here who works for this company. There is a discount for rollitup members, cant remember the code so ask him.
There are lots of folks on here who sell great lights and different kits, this is one example. I have no preference because I have not used any of them. Somebody else can list more companies.
I post this because I guess your from the same country as me and your not getting much response. Watch those Vids on youtube, you will be amazed!! It will also show how to assemble that kit ( you would need some aluminium frame)

Good luck in making a choice. Going off lots of guys grows and builds on here I cant see you been disappointed.

Mate I can't thank you enough. This is the information I need. I've got a great DWC setup although a 1 plant grow I train my plants well and have good results from my LED in a tight space but I want more bang in my bud. I've only just come across the ideas you've portrayed and it's all so new. I'm gonna go away and have a good read about on the link you have sent me and really look in to the possibility of building one. I oringally wanted to buy a complete arrangement but this seems to be the way forward. I'll probably return with more questions but cheers for help:bigjoint:

No worries, Its relatively new to me too, if I were wanting to build something for your size space I would be buying it yesterday but I want something for a much larger space so its going to have to wait. My learning curve was so steep with these ideas and I have been blown away with loads of whats going on on this forum by these folks. They are incredibly clever and have some amazing builds shown. Don't let it scare you away though. It can be very simple. As I said there are lots of folks selling pre built fixtures that are ready to go, using the same tech. So if you want to go down that route you have lots of options. I just don't know of all the companies names.
Do take the time to go through youtube and growmau5 's vids, there are many and some are very intricate in design but for your needs you can keep it simple.
It would be worth checking out some of Will Thayer 's threads on here too, he does some interesting stuff with smaller spaces and hes a stand up guy.

Enjoy your research!

Yeah what happened to the promise of remote phosphors, speaking of bare cobs. They were supposed to be the next big thing.
