Hello fellow RIU mates.

Looking for some help from some more knowledgeable COB builders.

Looking to get some numbers for a 5 x 5 space using Vero 29 V2 a 1.4A.
Reason Vero over CXB is here in Canada they are 100 per COB and just not at a price that will pay back very easily.
With that being said would like to know how many COBS I would need at above Amperage for 800PPFD.

I prefer to build in BARS of 200ish Watts.

Also as a side note would love to know how much wattage of CXB top bin would be needed for the same 800PPFD.

Reason for 5 x 5 as its very simple to scale up.

I am not a very Math oriented person , but if anyone could explain how to Calc PPFD for certain COBS would also be good. Simple terms as well.

Just a side note, in this 5 x 5 I will be running Blue Dream and GDP Kens Cut.
Want to test how well this performs under 4 week veg with my killer commercial strains.

Love the support here for LED and the COB movement.

Good Vibes, Trippy.

My 2 cents work is to watch Growmau5's Youtube channel and watch all 7 parts of the "DIY LED BASICS". Then whatever anyone tells you will make a lot more sense...just saying. And he shows some bar/cob layouts you will like and be able to use. Also, check out Tasty led bars. He discloses everything.

I have seen them. Says not in depth about PPFD calculations. Like I said, I am familiar with LED just not PPFD calculations.
My main reason for this post is to get PPFD calculations, not to check out Tasty LED PPFD bars. If I was going to check out any bars it would be PLC. Thanks. Hope someone else can answer this.

Looks like you need 387 radiant watts to achieve 800PPFD in a 5x5.

I believe the Vero29 v2 is 43% efficient @ 1.4mA so something like 900 watts.

Cxb is 52% efficient at the same current, so you would need 750 watts of cxb3590.

You can find cxbs on pacific lighting concepts' website, cutter electronics, and kingbrite on alibaba among other places.

This forum has a very helpful search feature. By entering "ppfd" into the search field and checking the box "thread titles only" you would have found the answer to your question in 3 posts.

Have a nice day.

Very helpful. Cree just isnt worth the savings over 8 years. Thanks as well.

With ya there on the cree vs vero cost in canada. you can get all kelvin of vero and there 35$ vs a 3590@ 95$ just not worth it for me for 7 to 9 % better. my2cents

You can purchase cxb3590's from cutter for 56aud => $44usd => 55cad with a 10% riu promo code.

Unsure where you are getting the 95cad price.

I am not in Canada so forgive me if there is a hidden Canada tax.

Dont know what electricity costs near you, its expensive as hell in CA and going cxb over vero with that setup would save you ~660kWh over 365 days.

That's my point as well. The new BINS are over 100. Hydro isnt very expensive in my province and 900w over 750 over the long run will take 8 years to recoup savings.
Also interested in the DE which is just over 800ppfd in a 5 x 5 with a 1k. However the heat.
Vero is much cheaper and worth the extra. Plus I dont use HLG as its just marketing. Reasonable chinese Drivers work just as good and much cheaper.
There is no room for cree cxb in canada. The price is just too high for the small %.

My hydro is very cheap. All cxb in canada are 95+ everywhere. Importing will be a pain with customs as well. Ill have a look at cutter and the riu code and see the prices, but still $20 more per cob isnt really worth it for the minor savings. Will have a look though.

Seems there are some better prices from PLC and Cutter but for my 5 x 5 build spending 360 extra per light isnt worth the savings. Which is 115 CAD a year less. Take over 3 years to recoup the savings. By then prices will be way down and new bins will be around.
CXB just are not worth the 115CAD a year savings, which is for 1 light. If you had 4 lights in a 10 x 10 canopy. Thats many more years to break even on electricity. I do see how it can benefit Euro and USA fellows with the high as hell electric bills, but here in Canada its just not worth it from my calculations.

Also what is everyone experience with lower ppfd for flowering. Say 550-650 vs 800 when running a SCROG between 4 foot.
Seen a thread and see some people killing yields which begs the question why more ppfd? I assume for taller plants, but would love to hear someone chime in as may lower my ppfd.

I got sick of running low PPfD with CDM. REALLY sick, when I discovered the magnetic ballasts I was running them on were inefficient both in electrical usage, and they drove the lamp poorly, hurting output. I got so pissed off that I went out and threw down on CXB3590, exactly because I wanted front of the class PPf/W performance, cost be damned! While I was at it, I was gonna leave the world of getting the most out of Twilight behind for good, lol

I built an array of CXB3590 powered modules, running each 72V chip at 54W, 4 to a Meanwell hlg-185h C700B. My Kill-a-watt says this combo pulls 225W from the wall, which neatly covers the driver's tax.

Four such modules cover a 4x6' trellis, generating some 824PPfD.

Thats some good PPFD! Would still love to get a comparison of say 600ppfd vs 800ppfd, yield.
I see many pulling 1.5-2 gpw with 600ppfd. Would be really interesting to know how much yield is affected. As for CDM. Never got into it due to COB and DE are by far the superior tech.
Wonder if anyone more knowledgeable than I can explain the difference on 600 vs 800 on yield and if its worth it. Seems COB and LED need to be studdied more to get the max efficiency out of everything. One step at a time.

Today's news is that just about the exact time we figured out how to get the most out of the 860W Allstart, Philips discontinued it!

So yeah, my decision last year to switch to COB LED is looking pretty smart right about now.

Indeed, COB is really great plus the lifespan out also a big plus.

You are going to need 1,250 Watts; 50w/sf 25 sf x50w = 1,250 watts total; to get where you are headed. Probably about 25 Vero's at 50w per COB. I do CXb's so I can say you can put 4-CXB3590, 36v on a HLG-185H-C1400B for 200 watts per driver. Six drivers at $68/ea = $408 (drivers), review the driver chart by SupraSPL for validation it looks like you can use two drivers HLG-120H-C500A/B for 12 Vero29's driving them at 500 mA per COB about 25W. prefered 50W so you wil have to use a C1400A/B driver to get there driving 4-Vero29's with a requirement of 6 drivers for about $400 in driver cost either way. The only advantage I see is the COB cost alone, all other costs are equal.. peace
