From the beginning

Which of THESE would you go with? How many watts should I go with. It was said to “go with a 500w lamp.” Is that accurate? Or any other suggestions?

Is there some reason you keep needing some validation of the info you receive? I don't mean to sound like a dick but bro ya keep asking the same thing.

The wpsqft formula I gave you is the guideline. Give a gander at it. Tally up what you need in watts per square foot and make a decision.

Ya need 500w in a 4x4.....but...as I said before..ya can get away with less.

Come on man...let's get this thing growing.

I have run one of these in a 4X4 with good results. Of course I've also run two of them in the same tent when I had it packed with plants. They have it a little cheaper in their ebay store

Maybe you should tell us how much you are willing to spend, and we can offer some suggestions to fit your budget, though maybe not the whole tent.

My budget for lighting is $250 max

Then the one I linked will work for you. There might be some others a little cheaper that use an earlier diode like the LM281b. I will look around...

The ebay link to the TS 3000 is the cheapest light per watt over 400W and under $250 that I could find. I suppose you could wait for the 4/20 sales, but that's more than a month away...

^^ sound advice.

I saw that light, and didn't think it could possibly be 500W at that price. And it said "Power 500W" instead of power consumption or power draw. But I looked up the specs and it has 1056 LM281b diodes that draw around half a watt each. I may have to buy a couple for the attic. $190 with a $40 coupon, wow...

I use that 400w in a 4x4. Not quite enough wpsqft but it definitely does a good job. Eventually I want another 600w so I can run a pair of them in my 4x8.

May even jump to the 840w. Can usually find it around $300 with coupon. Another $120 and I can pick up a 1060w. Good lamps. I've not had issues with them.

Save some more money before you start growing. Lights are one of the most important pieces of equipment you need for growing good dank and getting a good harvest.
That's my suggestion my friend. If you get in a rush and spend the money you could have saved and got a better light with. Your going to regret it later when that cheaper light doesn't do the job you needed it to do.
The Spider Farmer 4000 is a great light and you only need a little more money to add to the 250 you already have.

That's how I convinced my wife to let me build a two story 20x30 shop in the back yard.

At what point would you switch from veg state to flower state?

Now I just run them on 12/12 from they are seedlings. I would get larger plants if I vegged them but I grow more of them instead.
