Most Efficient LED Light

Guys whats the highest amperage Driver that's out there?, can i not use any 36v DC power source at the specified amperage?

@CobKits I have would love to go the DIY Route, but the only problem i see is the stock availability of getting that many COB's i noticed almost every site that has only, around 50~ units, which is enough for 3 odd lights if i do what BCBlondes.com has done

he has 16 Cree CXB3590, in one fixture.. claims he gets 900W at the Wall hopefully that should translate to at least 500+ PAR WATTs

can anyone recommend a quality perhaps lab grade par meter? or any other optical sensors that can help me detect the output spectrum/lumens etc

$2,000 is absurd. What cobs are those?

You said most efficient and they're not! The bcblondes 16 cxb3590 would crush this in intensity and efficiency at same wattage.

Why do you always spout average
Lights as best when they're not best efficiency or anything really they're just average lights for an absurd price.

You could even do way better with chilled DIY and timber DIY. Or fluense or a handful of better options out there. That amate light only mildly covers a 5x5.

You have to be affiliated to this company there's no question now.
Dude, you're outta your mind if you think the Blondes (which Is great if you just want bland cobs) or any other light available could crush the Pro-9.
Everyone knows I'm not affiliated with the company in any other way but a customer posting proven results. So you can end that noise.
I can promise you, Absolutely NO Cob light will beat this thing. Even your very best DIY efforts will fall short.
This light puts out like 30% more total light them a Gavita 1200. Not to mention enhanced white.
You're crazy!
You do realize I was one of the first growers around here to recommend the BC Blondes over these other basic cob lights if it was a basic cob light you're looking for right?
You built a light n now you know hu! Funny stuff. Have you tried using multiple light sources like I have? All the different tech.
Stop bad mouthing the best company fooleto!

Is that documented anywhere?
Oh yeah! Documented grows w/ Pro-9. Sure. There's a a few. Allota small growers here so not that many. But some.
Me using multiple light sources. Yup! That's here too.
Me being one of the first to recommend Blondes instead of these other overpriced cob lights, yessir, that's right here on RIU as well.
Soon there will be a scientific study against many other LEDs to prove which is best to replace 1000w HPS. Amares Pro-9 entered the battle & I know it will smash on it.
I'll post the link once the studies underway & you can all follow along.
Guys, I don't wanna sound like some sales guy, I'm just a large scale grower. So, please don't provoke me to prove what I've proved over n over again. I'm done with that shit. I'm all about posting real time results like those on my journals.
All the rest is just cob-bobbing piss contests with nothing to back them. Let it go!

16 CD bin 3590s, with 800w output would be about 448 par watts. I'm sure you can find 16 of them somewhere.

You stated the Pro-9 puts out 30% more light than a 1200w DE. I'm just curious if that's documented somewhere. A grow doesn't prove how much light a lamp emitts. Nothing you just posted indicates it puts out 30% more light than a 1200w DE. Is that documented somewhere or did you just make it up? Respectfully...

Respectfully , that's what I came up with after crunching the numbers. I will find out for sure because that is not something I should say unless I know for a fact, you're right there. I will check into it and get back to you.

@Rahz i need 800 COBs minimum to replace my 50 1000W Gavita DE
What? That's not exactly correct. You can probably get away with 400 just drive them a bit harder and you will get a good pull. Of course they would need to be spaced right and you don't have to follow the 1 per sq/ft guide.. Just use the calculater to get your desired ppfd

I'll take a look at your math if you like but it depends on the drive current.

At 2.1 amps each, 493x CXB3590 = 36975 watts x 2.3umol/j = 85,425 PPF
50x 1000w DE = 50,000 watts x 1.7umol/j = 85,000 PPF
Given the above calculations, and all other variables being equal, what would the difference in cooling a space with 50x 1000w DE versus 493x CXB3590?
Sorry for the hijack, but I though that should also be taken into account if we're looking at efficiency.

$pectrum King claims you can "Cool up to 8 Sk600’s with just 1 ton of AC". Not sure about that considering the source, but hopefully others with first hand experience might be able to speak to it.

COBs easily run cooler than any HID, light energy vs. heat emission.

Bare bulb for sure

cool tube HID vs Maxed out cobs could be a close one, but cobs fitted into ducting being vented outside, you`ll be running crazy low temps for sure
Yeah, but then you have to pay for more energy. Not saying it won't work, but it's less long-term cost effective, and you'll be contributing less to the eventual energy drainage issues that Legal States are facing currently, where grow ops are consuming nearly everything as the energy is being generated, which will probably eventually lead to the demise of HID anyway.

The cob setup I quoted would produce about 75% the heat of the bulbs. That would be the baseline figure, but cobs radiate less IR so heat management will be different even if the solutions were identical. If the lamps are ducted that will also change things.

In an unducted scenario, I've been told it would require approximately 15-20 tonnes of A/C for 50 x 1000w DE. All things being equal, if only 25% of that is required for a COB setup, that's a very compelling contribution to the overall efficiency.

and if you sub light with reds and deep reds you can get away with using less lights overall plus people forget to factor in that you water less and how much easier leds are to aim, plus no broken glass or hot glass to get hurt on

Most leds are running between 12 and 50V so pretty safe vs a 400v hid, then again I do like me some 500v+ induction lamps for veg and finishing but that`s a risk I`ll take to get blues and uv`s cheap, lol

^true, but it only takes .2 amps to kill you if its any longer than a shock. Volts don't kill, they just hurt. something to think about.

Actually you kinda right I would rather take a high voltage low amp zap

dc is not fun as you stick to it but even big led lights are using a few drivers 50v @ 4 to 6amps is about the most I see led users putting down a set of wires where as on start up I dread to think what a 400v 1000w gavita is putting down the line......... still they do insulate their cables a bit better then your average diy led rig

Still like old school electrics where you just have 2 big copper lines on the wall

Shoot my DIY cost me 1200 and that's a good setup, next should be $850-800 and be more efficient. It's all about knowing, some peeps just don't get it and others try to exploit the ignorant.
Yeah but DIY is much better. So you get more. My DIY was 16 CXB 3590 from timber and is awesome as it should be. Covers a 5x5

I'm just speaking of how amare is way overpriced average lighting.
