The key to longevity of these fixtures is to run them soft as Rockets stated before. He recently posted something a page or two back about diminishing light output for led units when run hard. Worth the read.

Thanks guys I really appreciate it. I'm hoping to get a few years out of them because I'm not exactly made of cash these days Stay lifted my friends!
Very cool. Only thing I can say again,is that being built into 3 separate fixtures with 2 boards each, would have made hanging heights a lot more versatile.I built this for my 4x4 using boards, strips, heat sinks and drivers from King Brite. So far they’re rocking it.

So yes I’m in the boat of more boards for any space. I have the ability to dim each pair of boards separately from the others as well. Plus running them soft will greatly extend their life. Once China is back up I’m ordering 3 more boards and heat sinks so that my next run will have a total of nine boards, each group of three on their own 240 making it light spread city in there. I’m messed up like that lol but If you want to go that route, I’d recommend 6 individual boards per 4x4 to get a solid even spread. Problem you’ll face going that route though is the amount of drivers you’ll have on one circuit unless you simplify it with 2 drivers.
It all depends on what you wanna run them at wattage wise. You could use a 48v driver that's 12watts or 600. So each board could get 1 watt or 50.what's the lowest number of drivers needed for 12 boards and what driver
I agree, but baby steps my friend. I like the process it will be a modular design at some point.Very cool. Only thing I can say again,is that being built into 3 separate fixtures with 2 boards each, would have made hanging heights a lot more versatile.
id say go with two 600’s. 100w a board is pretty nice. Although I gotta ask, what’s the electrical like? Will the entire tent be on one circuit?what's the lowest number of drivers needed for 12 boards and what driver
12 over a 4x8 what should I want to run them at for flowering?It all depends on what you wanna run them at wattage wise. You could use a 48v driver that's 12watts or 600. So each board could get 1 watt or 50.
4x HLG-320H-48A or HLG-240H-48A MeanWell drivers for each 2X4 fixture of a trio of boards getting 110/80ish watts each board. Dependant on what driver you go with. Either the 240watt or 320watt. Or you could always do 2 of each and put the higher wattage fixtures on the 2 outer edge spots.12 over a 4x8 what should I want to run them at for flowering?
Oooooweeee you can have some fun with that! And yes, what Airwalker said above. I always lean on the side of overkill so I’d go with the 4 320’s. If you run each board at their full 125w they run pretty hot and you will almost guarantee diminishing light output over a year or so.I have a 30 amp breaker for that room. Ive been using 3 600w HPS in that space, ready to make the switch to LED.
