First question you need to answer, is what's your budget.

depends on the LED
Not all are equal.

Very efficient LEDs using for example Samsung 301b diodes or equal you want 30w per square foot.
Cheap LEDs like 95% of amazon blurples you want 50w per square foot

Ignore the "2000w grow light" title , look at the actual power draw/consumption.
You wont be able to afford a good LED to light your space for $100 though.
I would look at 315cmh rather than cheap LEDs.

I use two of THESE in my 4x4 and have had great results with them. My first grow was in a 32" x 32" with one of them and I yielded 6oz which is pretty decent for a first grow. They aren't as good as QBs but they are good for a budget grow.

The should be offering me coupons for all the people I recommend that damn light to, too! I expected it to last me maybe a year when I ordered the first one but it's still going strong 2 years later. I'm hoping to upgrade to an HLG setup soon though.

Unfortunately I don't see a price to get any idea of value for money.
No doubt they grow, but at 300w it would be a bit under power for 3x3ft.

Me too!
If I had a £ for every time I had recommended a good LED. I would be rich.

The price fluctuates almost daily on that light. It's currently selling for $99 USD but I've seen it sell for as low as $89 and as high as $129. They sell an "1800W" version that would probably fit a 3x3 better, but I have no idea how many watts it actually consumes, because the specs still say 300W, which I find hard to believe, because I metered my "1500W" and it pulls almost exactly 300W.
