im gonna be getting the "light engine" from cobkits.com and a HLG-185H-48a driver. but id like to know what i should run it at for the most umols.. not umols per watt... since ill be using the single light i want the most lumens/par ect i can get from it with out causing too much life span loss.. is there a way to calculate this?
the driver is voltage and current adjustable.

I know thhat if you have it on a graph it would plato and then spike for lumens per watt. IE if you push it too hard youll go from say 120lm per watt down to 70lm per watt...

what im asking for is the magic ratio.. how hard can I push one single light before it starts to not gain any more lumens..

of course you have to up the voltage when you up the amps.. like fuel air in a car....

but what is the ratio get the most lumens and have a fair life span?

think of it of asking how much psi can i put in a turbo on an engine before it starts to damage things.

Just like a car the cooling system need to be able to match how much power your pushing.
So if all you care about is umols push it as far as your cooling can go or the limit of the drivers volts or amps.

CLU-048 1818 Data sheets: 90 CRI Version
70 and 80 CRI Version

The HLG 185H-48A (48Vf or 4.8A) driver at maximum will not push the limit of the COB you are going to use. The maximum recommended voltage for the COB is 56.2 Vf (5.62A)

basically id like something around 20,000 lumens. if its possible out of one chip. hopefully the 1818 cause its cheap and the hlg185H-48A should be able to get the chip to push that. or should I go with that driver and a cxa3950?. I want the most lumens for the least upfront cost. that is the idea. efficiency doesn't really apply to me. power costs are minimal.

I want this but as a light..propane secret..100 to 114 octane....also winter washer fluid...good back up to methanol.

You need to use 185-54 driver. It will deliver full wattage. I run 4 of these on one and it pulls 226 watts.

Same with pure ethanol ~108 octane.

...except you don't have to pollute the groundwater to produce it and there is an infinite supply as long as the sun shines and the plants grow.

the reason why you guys get polluted ground water is because the laws in America are retarded and have no safety standards. I live in a place with 1000's of gas wells and not a single water or ground water issue.. why.. a thing called a secondary casing. something amercunts don't know about or use. it protects any ground water from leeching into the gas well. and it is installed before the main casing to prevent any leeching during drilling

I plan on running only one cob for now. would that be too much for it?

As you add more current the vf goes up. The driver will limit the current severely I would think. The 54 volt driver is the correct choice if you want the kind of power pushed into 1 cob.

I see you are using A type driver it may work info that configuration. I'll check and edit post.

also im gonna have to frankenstien my current cxa setup.. i might even use wood to make a new mount so i can have all 3 cobs running and have the bright ass CLU in the middle ..now the real question is wtf colour temp should i go for. my cxa's are 3000K 80cri z4's..should i go with 3500K or 4000K?

the one 1825 chip should put out as much as both of my cxa chips. so what would be a good colour temp to mix?

you need to play around with the citi calculator for a bit

is your 3000K working? why change?

i want to try to best imitate sunlight.yes my 3000K works but I think if i provide the plants with an even wider spectrum of light and perhaps even provide UV on top of that. the results of my end product should be better. I don't think people have learned everything about what spectrum of light is required for what mechanisms the plants have. we are just now discovering things. for that reason i would like to try to provide as wide a spectrum as possible to my plants. just a few years ago people thought red/blue was the way to go...but side by side results prove otherwise. i think every spectrum of light plays a role in the plants development and responses..

well just keep in mind your 3000k cobs already have a very broad spectrum and adding different color temp cobs doesnt give you any wavelength you dont already have, it just changes the ratios. the exception being 90 cri cobs that go up into 700+ nm where you are currently prob using 80 cri
