Fanleaf's Huge 42 COB Array Build Plus Other Builds

I'm Canadian. It's not that viable after shipping and taxes. If you order from Cutter you'll get a tax bill after. (See my Cree CXB par test video a few pages back).
Cheapest option for Cree is Cobkits. You can get the driver from Mouser Canada. It will cost around $320US ($425 CAN) for the chips and heatsinks plus shipping. The driver is around $100 Canadian. Metal can be bought at metal supermarkets. They have stores all over Canada and deliver.
It will cost roughly $525 CDN to build a 5 cob Cree array sourced locally. There are cheaper ways to build an array though.

I appreciate it! The Luminous CXM22 has my attention at half the price, that could buy me twice the light. Spectrum looks nice too, I haven't jumped on any band wagons yet so I'm open to other options besides Cree I just want something efficient.

I couldn't justify spending the same money on more blurples when I could have the real deal but Cree looked like the big dog as an outsider.

No. They lost the game until they come out with a new chip. The Vero c class destroyed them with almost 4000 μmols.
If you don't know how much that is. The Canadian sun at high noon on a spring day produces 1200 μmols. So the Vero 29 C is a little more that 3x the PAR of the sun.

Plus both Citizen and Vero have chips that approach the 660nm deep red spectrum. Cree doesn't have that in a cob.

A Vero 29 5 cob build will cost you under 400.

That's incredible! This is actually one of the most informative video's I've seen on the subject, nobody else really explains things that in depth.

Thanks man. I try.
Unfortunately the C series build is just as expensive as the Cree. (Almost)
The D series is my favourite. 36v still gets 3200-3400 μmols. I sell the 4 cob array for $600 shipped and the 5 cob square array for $700. Also shipped. Discount to 420 members. And I only ship inside Canada.

Go to future electronics. You can get the chips, driver, potentiometer and ledil reflectors there. You want the bxrc-40E10K0-D-73 SE chips. $29 Canadian each.

Hi guys amazing thread I'm definitely looking into the LED game and leaving HPS behind yet the Cree are a little out of my budget. And also Chinese eBay crap are a no-go.. so I've been looking at

Citizen CLU048-1212C4-353H6K2 in a
1.2m x 1.2m grow tent.

I know I'd need 16 of them with a mix of 5000k and 3000k or 3500k.

I'd love to have them dimmable for seed to harvest but also ran at optimum efficiency to save on electricity costs.

I need some tips on your professional opinion on what to run for max yield bang for buck and eventually I'd upgrade to Cree or Quantum board.

I've followed Fanleaf YouTube series and watched all of GrowMau5 series too yet the options of drivers still intimidate me as I'd love to get into this hobby.

*p.s don't know how to post pics with the 420 android app lol.

Any info would be grateful guys thanks in advance.
 
Jimmy already changed my mind on Cree, the new Vero 29's are capable of outputting​ 3x the umoles of the sun for about $30 CAD a chip.

Would I be running 2x HLG 240h C1400b to run 10 Veros at 50watts? Or what's the wattage I should be aiming for? Going to order all the fun stuff tonight and buy the frame parts now.

One HLG 240h-c1750 will drive four Vero 29 D series or Vero 29 SE D series at their maximum output safely. Around 70w.
The SE is a solderless connection recommended for those who don't want to solder directly on the chip.
