High power COB -vs- hps vertical shoot out

just coming in to watch.. ive been interested in the led performance,,just not compitent to diy myself a unit and i grow sog so a regular 200-300 watt cob is all i need.. just hard to decide witch one to buy so im slowly gathering the cash..anyways very interested to see results here...good luck.. also the electrical savings alone are a huge pluss if yields are even close to one another...

ok a few things here on cob power from my very limited experience.if your 3590 are 72v your getting 50 w per cob.but you didnt say what voltage these were or i missed it 2x i read the first post.if your using 36v cobs your only seeing 25.2 w per cob.so if you are running 36v then your total watts is closer to 302 for the 12 lights.that could be why you dont like the results.but even at 72v its not nearly enough light to compete with 1000w lamps imo.but its all in the details.you can thank trolling charlie for inviting the whole led section over for a looksee lol.i still dont see why he thinks he has a horse in this race though lol.another thing,that driver is capable of running 8 x 36 volt cobs 3590 or 4 of the 72v cxb 3590 either way would get you to 200w per driver if you just use the right amount of cobs.but i hope you dont give up so quickly and try to sort this out for at least one more plant.to be fair the next plant needs to be in with other plants so it recieves the same overlap lighting your other plants get.that or pull 2 plants to the side and light em up individually .look forward to your updated pics.peace

Let's go over to the thread you started because I'm not finished with you yet. @legallyflying I got you I won't muddy up your thread I'm here to help I actually love your idea just needs a little tweaking lol @chuck estevez you have dug a grave for yourself with me lol. Guys get ready for the circus because I'm gonna make him look like a clown when this is all over hahahaha

Chuckie already does look like a clown. Just don't get any of his face paint on you.

I agree with you, I think @legallyflying is very close to a winning setup and a few tweaks will get him there. Link me in wherever you go to talk about this, so I can learn right along with y'all!

I ended up with 4 x CXB3590 3500K 72V CD bin per Meanwell HLG-185-C700B. This gives me 54W per COB at 56% efficiency, due to the B model externally dimmed driver running 8% over its rated current when the dimming leads are capped. This is good for 824PPfD over 6 sq ft, so I made my modules long and skinny to deliver even lighting to a 2'x3' area. Four of these modules nicely covers one of my 4' wide by 6' tall trellis panels.

This isn't to brag at all; I really only know of this and a very few other combos, I'm sharing in order to let everyone know what I'm running so they can compare their results.

Seems legit I'm hearing reports here and there of 1.9 gpw horizontally.

Yeah, that's why I settled on this combo. This way I can be sure any shortcomings are due to my incompetence and not the light's fault!

Please give details of the cobs and drivers.

Sounds like he should be getting 25/26w per COB @ 700ma amiright? 12*25 --- 300w, 75w per side...

@legallyflying You might just need more light. Im finishing a few 5 COB 54" panels, running 185h - 1050ma. Should be pushing about 180w per panel instead of 75w.

That or switch to 72v COBs

typical ttystikk with the personal attack because you know i am right. another prediction, in 1 year, you wont be able to sell that monstrocity youre building to a 80s cover band for stage lighting.

legallyflying said:

What's wrong with this is that you jump into a thread, spew garbage from some other nonsense thread, and can't even bother to look at the very 1st post in this thread that shows exactly what is going on.

You diss the build in one post and the very next post ask what the details of the build are
What's embarrassing is that you are an advertiser and this is how you roll???


ANYWAYS, I'm looking for suggestions from those in the know. Maybe lenses on the chips?

What I was referring to was the OP.... 12 cobs and 200 watt drivers I'm having a hard time figuring out 800 watts on 12 cobs honestly. 16 cobs maybe. I'm assuming you are running meanwell hlg 185h c"""""" so still can't figure how you got 800 watts on 12 cobs.

If you have the incorrect combination of drivers and cobs you'll definitely not get the results you are looking for. Have you actually plugged it into a kilowatt meter? Not bashing just seems you are quick to dismiss this tech when your design is not quite optimized. Sorry if I came off as being a dick.

That's what I was thinking and of course he got lackluster results if this is the case.

Or really awesome results if he was using half his expected wattage...

I'd rather have the yield than the low power bill, speaking personally. This isn't a desirable result at all, even if the unit is operating at high efficiency. If the driver is underutilized then it might not even be all that efficient. That discussion is for those who know their power and parts better than me.

In the OP he was thinking 800 watts. If he is actually 36V cobs his best bet would be 3 hlg185h-c1400b.

Depending on the heatsink you could run 3 36V cobs per hlg 240h-c2100 for 75 watts per Cob basically.

Or 4 on hlg-240h-c1750 for 62 watts each. This combo would get him the closest to his 800 watt goal.

I'll look into those parts next week, we JUST flipped flower room A. Right now I'm dealing with the uninsured and suspended license jackass that plowed into and totalled my Lexus that was parked on the street.

I hear a crash, thinking someone is breaking into my motorcycle trailer I grab my handgun and walk outside in my underwear to find my car and his truck in a mingled steaming heap. Then, this guy starts walking away!!! I'm like hey!! Where are u going and he says, my friend is in the car I'm going to get help. Oh shit! I think and look inside the car... I don't see anyone. I look up and his is sprinting down the street.
I fucking bolt after him screaming stop stop, ive got a fucking gun and he kind of freaks out, looks behind him and trips. Now I'm standing in the middle of a fairly busy street in my underwear with this guy at gunpoint screaming stay down, do not fucking move you are under arrest.

The cops were surprisingly chill, even joking around and what not. After walking home and putting my gun away one cop says "oh hey, I didn't recognize you without your underwear".

My gf... whose car was in front of mine and also damaged was on FIRE becauservice she just bought that mini Cooper last month. The guy is cuffed and bloody on the curb and she is yelling "your a piece of shit you fucking dumbass" etc,etc. And the cops says "mam, you can't berate the prisoner" and she says "yes I can he fucked up my car and then tried to flee" and he says.. "ok, I'll give you 30 more seconds and then you have to just go home" lmfao.

She should find out when the piece of shit is due in court, THEN berate him! Make that shit count; judge will hear what she says and fuckin bury his dumb ass in jail!

WOW! I hope you have no problems with the insurance company. Glad no one was hurt though. Life is fuckin crazy.

Well he had a felony suspended license...and was driving, which is a felony. And then felony hit and run, so yeah he is going to jail.

Absolutely fucking crazy though. I thoughy, ok, ill go in the back yard, see nothing and then go back to bed...

Fucking loved that car though

Just stopping in to see how this turns out.
