Between $1-$2 a watt.

Thank you.
And how much cheaper than store bought you think? From a well known led company except mars. That shit is shit.

Help me out here guys. How is it possible a 143 volt driver can work on 4 cobs in series at 1400ma that take a total of 147 volts to run. Basically run 20 CLU048 1212 with 5 hlg 185h-1400b drivers. I've already been told it won't work but I seen with my own eyes that it works and works well. The 4 cobs were mounted on 5.88×36 inch heatsinks with 3 fans on each heatsink. Temps never get higher than 30c. Someone please tell me how this is working.

You've been told it's over 100% load, not that it won't work. Analog electronics have a buffer/fudge factor built in, each individual driver will behave differently in that zone. The only specs guaranteed are in the data sheet.
If you are worried, spend a few bucks more and buy the HLG-240H. This really isn't that complicated.

Best 300-600w LED for under $400? Looking for full spectrum with UV. Goal being one top quality plant with as close to a lb yield as i can. Thanks

I don't think there's actual UV in any LED fixture except the Amare with the uv-b fluorescent bulb in the middle? I see a lot of cheapo blurples being marketed as Full spectrum + UV, but that's just marketing/lies.

Alot of people on here recommend that brand but id like to avoid spending 7-800 on a light lol

Back in the days of CXA(long before most here today)...I put 4 cxa3070(~37v each) onto a 185-1400b. voltage was ~148.2v on the string. The driver current had to drop to 960ma to handle them. Could have ran a 1050 version correctly and gotten more wattage, and been within specs of the driver. 100% load on a driver is working full/hard already when ran correctly. Not sure how longevity would be when doing that for extended period.
Hps is the only thing within that range, and would have less heat than anything that claims to be in that range.
There is not a beginner/entry LED. LED's are not to the point where any joe shmo company can replace HPS...and specially not for about the same price. And the ones that claim it are not nearly as efficient or effective as HPS...and the operative word is "claim".

This is as close as you're gonna get to quality pre-built, for a DIY price as far as I can see. They tell you what top-bin they use & drivers. You can buy cobs & drivers from them too. Good looking fixture I think. I honestly have no idea why their are no threads here w/ these lights growing something.
Then again, most threads are DIY or the pre-fab DIY.
Again, you're at $2 a watt.

This looks like a really good led. @142000 lumens bright af
And at about 1.60 a watt

You could build a fixture using the cheaper cree or citizen chips, something like the citizen 1212c4, use 12 to cover a 9 square foot area. Veg one plant into a tidy scrog.
Running 12 cobs like those @1400mA would give you
88400 lumen
PPF of 1180
PPFD of 1412
That would grow some nice plant!
Cost of $151 for the cobs
$86 for the heat sinks using a 1.813 profile
around $150-$180 for the drivers, rough guess.
Extra for frame to build onto, thermal paste, wire ect. Not sure on those figures.
Rough guess it would cost you $100 more than your budget, maybe less
But with 44% efficiency would out perform a LED single diode panel which cost more.

If i can get around a lb off one
It would always be ideal to build your own setup, especially price-wise but im lazy so im talking to an electrician friend of mine see if he wants to help...if not im just buying one already made...ill pay the labor price lol atleast most are made here anyway

Don't blame you for not wanting to build your own, the more you look at what other folks are doing the less daunting the idea becomes.
lol says the guys who hasn't built shit yet!! (me)
I don't see why you wouldn't be able to pull a pound off one though. I can pull a pound of a 600w hps in that space. Never tried with only one plant but that doesn't mean much.
I may have been conservative with the driver price, I was assuming you could get away with 3 and it may be you would need 4 priced at $50 each.
If all you want to do is pull a pound of a plant why not go hps until you can stretch to building something super special. Its a way to start off.
There are lots of folks on here sell COB lights, just not sure they fit in your price range.
Which ever direction you turn, good luck with your growing!!

Yeah man im used to working with the hps, but ive heard good things about the energy effiency with LEDs and a cheaper monthly bill would be nice

He used a driver that is 300w rated.
