New CREE COB finally launched

[CobKits]

CXB3590 for the win

they are good cobs that perform as well as others

your garden looks great, but it is 100% because you are a great grower and 0% because of the name on your chips.

Now the DB CXB3590's are worth more when you can get them

again there are chips that are equal in efficacy for cheaper. Paying more for the name on the chip may be worth it to you, but for the typical grower who just wants efficient chips at a good price there is no advantage to spend more on chips that arent any more efficient than the cheaper ones.

But they are not the same in lm/w at 700ma

have fun man, im out of this thread

CXB3590 for the win and DB bin will be available once they get the formula right, that why they are not available yet because Cree hasn't been able to get it consistent yet. I still know why everyone is buying the other cobs. It's price that's making your decisions and Cree is making a big mistake with those chips because you guys are cheap lol. Now the DB CXB3590's are worth more when you can get them lol. Just look at my plants lol I think when I show the results I get will change a lot of you guys mind lol

Day 1 of week 4 flower all organic no AC. I don't want to post my PPFD it will start fights lol I have meters just look at my old post lol

thats a nice garden

After building my LM561c boards at an estimated 170lm/w at 300 watts I can't even pretend to be interested. The spread of light is so good that i hardly have my lights at 200 watts, meaning I'm prolly around 180 lm/w. I understand they are pushing 1800mA but at 1.8amp my lights would be 162ish lm/w but the light would be 365watts give or take.

It's nice to see improvements either way... that being said I believe samsung will have a upgrade to S7 bin at some point for like 2% better efficiency, not really worth it but I guess it's better!

Samsung is already moving on to the LM301B. Doubt there will ever be an S7 bin.

Ah, I just remember seeing something about their new chip being a 2% upgrade. Maybe I remember the name wrong.

They are already using it on their new Q series strips.

Digikey already has strips with the LM301B. 3000k at 188 l/w !!! nice

we might be cheap but we are not stupid .
So anyone show any interest for those DBs you've been auctioning for awhile? most of us are cheap

lol I sold @SupraSPL 10 of them and he did some testing and if I say what his findings were you'd say I was lying but the DB jumps to 61% efficiency @50w which is 5% more than the CD bin

ive seen this same increment in my own testing.

I'm not sure if setting up a super efficient COB bank is the right move for all.
It normally costs more as you use more COBs at lower power. Considering you still need 3 of those banks to really compete with a 1000W HID over the same floor space.
Maybe OK in a tent or box. We needed to cover a large floorplan so we just brute forced it with cheapies.

SO, how does this compare to CMX22 for example?

he should post his results

DB should be 5-8% more efficient than CD bin, considering that's what the bins mean.

cxm22 is about the same as the DB 3590 below 50W, nobody has seen this new chip yet

The whole trade-off hinges on your cost of power. If your electrical cost is cheap it makes less sense. If your profit margin is high and your initial capital is low then cheaper is better!

 

[pop22]

Tests done in a sphere? Because anything else is less than reliable

CXM22 3000k or 3500k 90CRI best for flowering ?
