Watts is a measure of energy used, nothing to do with the output of the bulb. If watts are what mattered incandescent or halogen would rock. It's about the output energy, the par watts (mols) or lumens (for human eyes.)
A 1 watt incandencent or halogen could produce as little as 8 lumens, 1 watt of a 600 HPS would be about 130 lumens...

They come in 2700 and 5000. There are also 18w PAR38 spots and floods. (I'm using them for toplighting a plant in flower right now.). See my write up about these lights for more info.

30-40 actual watts per square ft?

AZ- that was all done with those from the jump??
I have 3 Blackstars. They're just rebranded Chinese epi-whatever lights sold at a premium for US support.
You can do much better for the money. For example, a 18w (120w actual) Blackstar "v2" costs $230. You can get an Area51 RW-75 for that money. It will grow better than 120w of Blackstar.
Don't get me wrong, you can grow decent plants with that Blackstar. I've done well with that light and also their 135w (85w actual) UFO. But, the RW-75 does as well or better with less watts for about the same price.
Yes. I was getting 90g from 85w of Blackstar UFO. Added 38w of Cree "lightbulb" as sidelighting and went up to 155g.
I have a 3' diameter plant under six PAR38 spots (and five 9.5w lightbulbs as sidelight) and it's flowering well. It's still early flower, not quite mid flower yet. Too soon to tell, but so far it's doing as good as anything else I've done.
(I have a little trouble following your CB-radio style of posting. One sentence continuations, etc. No indication who you're replying to. Forgive me if you asked something and I didn't respond.).
Ever notice how a 16w CFL says it's equivalent to 60w? What they mean is: the 800 lumens produced from a 16w CFL is equivalent to the 800 lumens produced by a 60w incandescent lightbulb.
Likewise, a 9.5w LED lightbulb produces 800 lumens. (You can get SMD5730 LED strips that produce more lumens per watt. Or, build a COB which does even more. Or, buy an Area51 which does more.).
Lumens aren't a good way to compare grow lights. But, since we're comparing white lights, it's ok. (If we were comparing blue/red lights, it wouldn't be ok.).

The only one that I have experience with is the Hans Panel, you can get one for under $400.00. Ebay is the only other that I know about and it's not recommended by me.

Your setup is 6sqft. Most folks on this forum are going to recommend 30-35 consumed watts per sqft. So you're looking for a light that hits 180-200 watts with a reasonable efficiency (heat is an issue). That is going to be tough to do with 300 bones, or clams, or what have you.
A common misconception is that LED is always cooler temps and cheaper than hps. This is not so. Only the efficient lamps are. Most cheap LEDs actally squeeze less light energy out of the electricity youre paying for than the dreaded HPS or CMH.

For under $400, you could look up:
Area 51 RW75 or W100 (http://www.a51led.net)
Any Hans panel in the range (www.bonsaihero.com)
Kessel up to 4 H150 purple or magenta or a single H380 (http://growershouse.com/lights/indoor-led-grow-lights?c2c_brand=7925)
..... or you could go generic with something like a Mars Hydro panel, which seems not to be recommended by the more technically savvy members here, who might tell you to go with Cree bulbs for less money anyway (right @az2000 ???).
You could probably get coverage of a 3 x 2 footprint with 2 65W Hans Panels ($460 for the 2 with shipping), but I don't think they would give you penetration for tall plants in an 8ft high space. Might be nice for short indicas or maybe you could add cheap side lighting, like az2000 and captainmorgan.
From reading the DIY threads, I would guess you could get some nice components with that budget if you have the skills/desire for that.

the ceiling is 8ft tall, ive never had a plant that tall though. I checked out both the hans panel and the area 51 which one of those 2 are better, i know nothing about LEDs
