I'm tired of the sorry ass hps guys talking shit because they are scared of the truth. The new cobs kick the shit out of the HID's and the HID companies are trying new tricks. I've been growing for over 10 yrs and I've never had a room so quiet and cool without extra fans and I'm running no ac now. All they can say is led can't produce which is a fucking lie. It's like the Flinstones meets the Jetsons lol and cob users are the Jetson lol

No ones scared. It would be nice if you'd keep it cool for a while. I might be miss judging you, but your keep running around the forum like your the king gardener or something. Seen some of your insults and their quite embarrassing.

Maybe for you but not for me this is only a blog and you don't know me in the REAL WOLRD lol I'm friends with big people on here and I'm not saying any names. If you can't handle how I am just hit the ignore button and lose out on what I have to say. I'm saving peeps money and a lot of it as well. So deal with me being me. Btw the dog has grown so much and looks great, I remember when he was a pup when you posted his first pic up. I love dogs but some people are stupid and I act the way I do because I can back it. Today is my sons 24th B-day so I really don't worry about the net and how people feel about me that don't know me REAL talk

That is correct. Many hps-users only know hps and are not able to open their minds to other ways to generate Pars. It is almost funny: in my country I am on a forum for about a week and I have stated my result of with white leds (0,95 g/w), they don't believe it, they just don't. There are are only a few people who try it with Chinese leds (the pink gaylight) and it does not work. You see the plants on the picture and you know the plants miss very much good light. And some of those people are still buying the Chinese crap from salesmen saying: this led is 300 watts but generates light for 800 watts. :wall: No par readings, no info, nothing. Just really amazing those people.

But don't be mad, they can't help themselves. Let them think dat hps is the best. We all know better on this forum, it is proven that you can get better and bigger results with led.

So how many of those cobs would someone have to run to compete with 20 1k hps bulbs?
For a comparble lumen output wouldnt you need a crap load of those cobs and drivers?
I was going to build an led rig til one of the led gurus told me it wasnt worth building since it would only wind up 40 000 lumens

Depends on what your goal is. You want to save electricity? Produce less heat? Deliver higher light density? ...?

Lumens are not good measure for plants. Generally, about 100 lm of typical white LED spectrum is equal to 115-120 lm of typical HPS spectrum.

What you need to think of before you start, is how much efficiency do you want? The efficiency of hps is about 36%. Leds efficiency can be about 50% or 60% but you need to run the leds on low amps and you have to use more leds to get the same amount of watts.

You need to compare PAR-Watts of leds and hps and do some math, you can use the spreadsheets of Supra for this. https://www.rollitup.org/t/cob-efficiency-spreadsheets.865238/. 20.000 watt hps would generate the same amount of PAR Watt (7200) as 342x cxa 3590CB @ 600mA., a total of 14.400 watts.

almost 15 years experience, 20,000 - 50,000 watts at any given facility over the years. Now finally trying cobs, and so far so good, they are unreal. Best ive done with HPS is 1.9 a light, which is about .80 GPW (1070 ACTUAL watts for a 1000 watt hps with ballast), first go with chinese leds was .45 gpw, but now using cree cobs and have about 50 cobs in a test lab. I like your posts RS, keep up the good work.

Nice. I've got 15 years under my belt but never got over 10k.

I think a lot if the guys are hesitant because for years, decades, they have used HID lighting. HPS and MH had been tried and true systems. Also, if you have been doing this for 10 years plus you've seen a lot if snake oil bullshit. The original LED ufos being one. We remember all the 90w red blue crap that claimed to replace or outperform 400w HPS. Mix those things together and add in the cost differences from HID to LED that has resulted in most LED grows to fall into the micro or small grow category with not much to judge on a more broad/larger scale. I know I was very hesitant at first and all the bull shit companies with their crap quality or marketing gimics made it a confusing cumbersome task before lots of research. Slowly HID guys are checking it out, whether just experimenting, supplementing, or fully converting.

So u would need 342 of those cobs? And 342 drivers?
Wouldnt that cost more than you would save on electricy and everything?
Like i said i dont consider myself anti led im just not sure when you consider cost to build and equipment it makes it that comparable.

Commercial would do better to follow a different design I think..

From just a quick idea, I'd just run aluminum/steel framing over a large area for starters. No separate heatsinks. Have outlets along the framing, and just attach cobs and drivers as you go.

Oversimplified, but that would be my approach. Once the framing is up it would be easy to add in cobs. Cooling could just be ceiling fans..

I've also never run over 600w..lol. Just an idea. I'd do that before I'd buy new bulbs regularly..

To be a fair and true swap for 20kw worth of hps...you need about 255 cxb3070@1.4a(mid driven, where price and efficiency blend best and still superior to sodium). And could run that on 64 drivers. Looking at an average overall savings in the 50%+ range for both lighting and cooling...whatever that means to you and your areas cost.

The best commercial warehouse grows use 1kw DE technology not just normal HPS in an air cooled hood, you need the best of the best LED's to even compete with them and it's closer than all you guys act like it is, LEDs aren't destroying HPS you are delusional to think that.

What Pos and Green said... look for large and efficiënt drivers, meanwell or so. The harder you run a cob, the more cooling it needs, the cooling can be active or passive. Good cooling makes a cob run more efficiënt.

-edit-
Look at your budget first and then decide how many hps you want to exchange. To replace all hps for led in one time, is a big challenge. Why don't you try to replace 1000 watts hps for a few leds to get experience with building these lights. When you have enough money, do not run them on 1.4A but run them slower (more efficiënt), its a small one time extra investment and you will profit from it for 50.000 hours or so.

The best and easiest way to build such lights is to use long alu frames/bars where you can connect the heatsinks with the leds on. And you can put all the drivers on the wall.

The thread you should read to learn everything is https://www.rollitup.org/t/diy-led-cree-cxa3070.789575/page-168. There a some people who show their own builds and where you can profit from.

Hey man who really cares about what anyone thinks use what u want and if u get good results then be happy, but talkin a bunch of shit isnt the answer. im guessing ur mad cuz u see what hps lights can do and ur not getting that from ur LED i could be wrong but u dont have any proof to ur claims lets see what u grow with ur light and what others grow with hps, i kno that im a newer grower ive had about 5 crops and working on one now i have a very small space so i use 150 watt hps and i love what i see

My white cobs have done a much better job producing light and weed than my old HPS setups have.

Pictures from my 230W vero setup and my 193V cxb setup here.

Also check out positivity's grow and greengenes's grow before assuming we can't the same results as HPS.

150W HPS in particular is not a very efficient version of an HPS lamp, btw. Have you considered cxb? lol

Wrong wrong wrong. Dude you're still a baby at growing I can use 372 watts to veg in a 4x8 tent

The guys hate it when I say I use to grow for a dispensary and I grew in 2 10k flower rooms 1 4K veg and 500 clones a week matter of fact look at my last harvest 2-1/2 pounds off cheap china led lights
