how many watts to you think I would need to properly light up this space? What could a feasible yield be in a tent and what would be the best way to do it?

I just built a DIY bar out of CXA3070s that pulls 220W at 3000k. How many of these would I need? These are 36 inch bars

You really think that many. What kind of yield could I expect running some commercial strains? Assuming I top, tie, train, the plants.

I was gonna say 4-6 depending on efficiency.... 6 is 1320 watts good for 31 watts/Sq. Ft.....
[Example: 40% efficiency = 528 PAR watts....528x4.66joule/PAR watt = 2460 PPF
2460/ 3.9m^2 = 631 PPFD average
@PurpleBuz might have had the closest guess, but that PPFD @ 1320 watts could also be raised with higher efficiency....10%? just by going to CXB3070 AB/AD, which could put you over 700PPFD...very good #'s....

Get some CXB3590's 72v at 700ma and be done with it this is my new light with 80 degree lenses
