Me. Lol.
No one else who ships to Canada can beat their price on the HLG.
Jameco is 30 cents cheaper but the shipping was more due to import charges.

Well, that came outta nowhere, no wonders i hadnt a clue what you were talking about. You hadnt been in here a while, dont you? How many veros you drive?
 
3 COBs per driver. I'm up to 9 COBs now. I just ordered 3 of the new Vero 29 D-73 series. They boast 11500 lumens with better efficiency and can handle much more amperage overdrive.
That's why I need the HLGs. You can overdrive the hell out of them with the onboard pot or via smart dimming.

The next step will be decide how much of each chip i will buy.

I want 50 Cobs for 3,5m2. 30W each. One big room from seed to bud. 10 rows with 150W each.

I can choose from 3000K80Cri,3000K90Cri, 3500K 90Cri and 4000K80Cri. I have to buy them in 5pcs trays of one colour. Also 5pcs will be powered from Meanwell 150/700 driver.

Now i start to find out how i place and wire them. I start with 20x4000K for veg and later I guess ill go for 20x3000k80Cri and 10x3000k90Cri for flower

It is my understanding that the 3500k 90cri is about as close to the sunshine spectrum as your gonna find. I would just load up on those. No one does it better than the old fire ball in the sky. So that's what I would put my money on.

I'm down in the 75 cri range with my new LED's and the white looks very close to outside on a summer afternoon. Very clean looking compared to my old blurple lights.

I dont know if the ELG have that Option too. I calculated 136W with 1750mA. But i can pull 144 when i crank up the external potentiometer. :) But as you can see i am not into overdrivin. I run my 82W Veros at a maximum of 68W... More like 50 and my 117W Clus on ~40. Much more Photons per Watt. I end up with almost 400W of Cobs for 2x3, thats too much i think.

My lighting setup is kind of a mess at the moment. Friday or saturday i get my driver for all the Clus, then i wanted ro rewire 4 cobs and their Fans besides work. I guess its going to take at least a week to get everything fixed and running.

So i decided to pull out my old mars ll 700 out of the closet and pick some parts out of it to Supplement my grow in its current veg state that was only running ~170W.

I cut out a piece of the pcu board/aluminum plate that holds the diodes for 2 of the 6 drivers. 50 Diodes to be precise. I just customized the spectrum. Pulled out some reds, soldered some brand new whites and yellows blues in there. Now i am at 290W

Took me an hour. Does only have to last a couple of month for some kitchen herbs and stuff, but i guess it will do much longer, cooler than stock :)

On the right is a Clu 1212 running on 1 mars 2 driver at 30W. Its hanging a littlebit lower without a reflector

Have a look

1750mA? My Vero's are 2100mA.
Are the CLU's running at 1.7A?
That would have saved me a huge headache. I bought the first set of Vero 29s the month they came out. Couldn't even find a driver that worked at the time. Had to use a DC/DC step converter from eBay which eventually fried half way trough the first Grow. Had to swap back to my 8 Lamp T5HO to finish the job. Then I tried the LPC-150-2100 but it would only drive 1 cob. Lol.
Couldn't win till they came out with the HLG's.

Yeah i am waiting for the HLG2401050A and one more 4000K cob. I really hope the 4000K is good for high grade flowering. The right you can see is not on my fixture, its hanging there on its own. Its a 1212@30W

4000k has a great spectrum.

I just put a few inquiries in on Alibaba regarding 130mm pin fin heat sinks for $14 a piece.

I think this 133lm w was at 250W per Chip. This should go up when you drive them at 80 to 100W. But i guess they will get hot af with their 38mm diameter at high wattages. We'll see. Whats the exact name of your linked cob?

digikey dot com/product-detail/en/citizen/CLU550-3626C1-40AL7G4-B24/1642-1196-ND/5820565 sounds even better. More lm/w. Maybe throw some of them into the mix. But what mix. 4 chips on a 3x3 would be enough :) i think a hell lot of smaller and cheaper chips soft driven will always be in advantage.
 
Still it's a good alternative to commercial high-bay green greenhouses that use double ended high pressure sodium at a thousand watts per end. Especially since they usually have about 30 of them running at a time.

The spectrum of 4000K varies from manufacturer to manufacturer. Cree at 4k puts out more blue and less red then Bridgelux fe.
