Blackstar 240 uv LED flowering model.
I've got one in a 2x2 tent and am most satisfied. Only runs on 135 watts even though it says 240. Five years before it loses power and no bulbs to replace, just have to get a new unit after that. I know the initial investment price on one of those babies seems like a-lot, but considering how little power it takes to cover a larger area, and how you don't have to buy a new bulb every other grow it's a deal.
If you do decide to get an LED light have a look around our lighting section so you know what you're getting into.
Other than that I recommend starting off with T5 lights.

LED = low power cost
LED = low heat, so no need for additional cooling or fans = saves more power cost
LED = a little more expensive than HPS,
...but remember - if you get the HPS you probably need a cool-tube, larger extraction fan and possibly even an air conditioner in the summer
The Piggy has you taken care of man, BS240 is PERFECT for 2x2. Make sure it's not more than 2x2 and throw a couple CFLs in to supplement. Here's the thread he recommended, check it out for some beautiful BlackStar shots.

so i can put any size LED light in a grow tent and not have to have an intake fan/exhaust fan?...... just the light, tent, and plants?
or did u mean u still need basic intake/exhaust fan just no additional cooling or fans.
No additional cooling fans...you need something to move air through the tent to maximize photosynthesis, but most LED's don't affect temperature by more than 3-5 degrees. In my 3x3 tent my blackstar 240 (when used in conjunction with my 600w HPS air cooled lamp) causes an average 5 degree temperature increase.
That's a sick thread L&S, I usually avoid icmag but enjoyed that read and of course it sparked the builder in me.. going to rig something like that up here in the near future when cash allows.. Just to put in another room and grow some multipot ladies.
And L&S is spot on, no additional cooling or fans - BUT.. what I meant was, I use a 465CFM fan for my 600W HPS in a cool-tube, the fan is 145W.. with 2x BS240's and 1x BS180 I cut the power down to 20% with a fan controller and had cooler temps than the cool-tube. 145*0.20=29W.. so it was like running one CFL instead of almost running another HPS, ya dig?

Yeah, and he got like 4+ ounces out of it! If I did that rig I'd do a no-drain TLO soil mix...anyway, that's getting off topic. There's a million ways to skin a cat, and I think LED introduces a level of difficulty because of their extreme intensity (nutrient use/water consumption are at odds and become problematic with sensitive strains that tend towards calmag def.) BUT they offer great value and incredible ease of use once you dial in your nutes/medium/watering schedule.
its hard for me to determine what kind or how many led i should get cause i heard the light isnt measured in lumens? so i dont really know what exactly will work maybe u guys can help..
How much led light would i need to grow 6 autos MAX.
right now in my 3x3 tent i have a 400w hps and would be able to fit 6 plants in 3 gallon pots in it, which im sure the 400w would be good for as ive seen people grow more under a 400 with good results.
if i got another 3x3 tent what size led would i need to put in it to grow 6 autos? i would want it to give me what the 400w gives me atleast i wouldnt want to downgrade can somebody let me kno whats up

2x BS240's would do you fine, or if you're willing to take the chance and order directly from Bysen LED you can ask for two SP111D-210W's and they'll quote you around $450-550 USD depending on location.. that's the equivalent of 2 400W HPS (what the BlackStar is supposed to be, but I believe, IMO, the BlackStar is similiar to maybe 300W of HID. The Bysen has the new X2 technology as well and is modular for upgrading.
If it's something you're interested in, PM me and I'll provide you with more details and contact information. They're on holiday until 2/23 though for Chinese new year.
This is the light you'd be getting two of; http://www.hydrogrowled.com/126X-PRO---200W-LED-Grow-Light-P85C60.aspx
Notice it's $900 on their site, you'd pay $450-550 for two of them total... almost a 75% discount.
