I'm currently running one 600 watt hps setup in my 7ft x 2ft grow tent, I mean my closet. One light is not cutting it for me. I was thinking buying another 600watt hps setup and just run them both at 300watts go up on watt from there till circuit pops. I'm limited to power wattage. My vary first grow light I ever bought was one of those led blue an purple light that was trash. I was thinking trying leds again. I was thinking buying Mars hydro ts1000 or Ac infinity Ionboard like 2x2 or 2x4. If you use an led light what brand and how do you like it?
I love AC Infinity products…except their lights. The only reason I would recommend one of their lights was if a grower was insistent on having "total"' integration of their light with the rest of their grow. AC Infinity has done a great job in that respect. On the other hand, the spectrum that they've chosen strikes me as strange and the light output is markedly lower than many other products on the market. I believe that what works to their advantage is that most growers don't give their plants all that much light and they've arrived at the understanding that it would be a poor business decision to design and sell a more expensive product that will not be used to its fullest.
If I were growing in a 2' x 2' tent, I'd go with the Vipar Spectra XS-1500 Pro. It's a stunningly good product. In a feature comparison, I don't know of anything in the market that can touch it. Price, vendor reputation, and spectrum are good but what made my jaw drop was how uniform the light cast is. Vipar rewrote the standard.

7' wide or 7' tall?
A 2' x 7' tent will need a much bigger light. In rough terms, input wattage of 30 watts per square foot is the minimum and 40 watts is better. Cannabis yield increases almost in an almost linear manner as light levels increase until you hit the light saturation point.
With a grow space that's elongated like that, you'll need to have multiple lights "in a row". Funny, I was thinking about that last night for my 2' x 4' - three XS 1500's, nose to tail, so to speak. Vipar sells two 1500's joined with a bracket. It's called the XS2500 and it's $200 on the 'Zon with a $30 coupon. You could do one of those + a single XS 1500 Pro. That's only 32 watts/sq ft but it's also just over $250. Maybe go with 4 XS 1500's? That's 600/14=42 watts/sq ft and you're rockin!
