Choosing a LED for 4x4 autos

Hello, first time grower here and a complete noob but I’ve spent alot of hours in the past couple of weeks trying to learn about growing
I have purchased everything for my grow and only needing a LED.
My budget is low I guess, I am from the EU and I could spend around 600-700€.
I am growing 4 autos in 19L buckets 4x4
My options so far are:
Migro Aray 8/ PRO 480/530Watts (560-660€)
Maxsisun MG3000 300W (291€could get two)
Spiderfarmer SE5000 480W(620€)
MarsHydro FC-E same price as spiderfarmer
Lumatek lights are out of my budget but there is a 400watt one that is on sale for 600€. Would 400W be too little for a 4x4?
I have also watched a MIGRO video where he recommends the MIGRO Aray 8 +RED for autos, due to its lower PAR.
I guess I should also consider that since I am a noob and I’d prefer to go without co2.
So would the MIGRO Aray 8 PRO be too strong for a 4x4 autoflower grow?
Would love to hear an opinion. Thank you for reading

From that list the Migro unit looks interesting and flexible. Like the dual drivers. This light or the Spider Farmer would be my choices.

Yes, I am more leaning towards the Migro but then the SE5000 is also an option. The Migro is 20£ cheaper

I'd say the fce. You can ask marshydro for a promo code maybe theyll help you out. Wait for the 420 sales. That and ~christmas time is best time to buy imo

The guy from Migro suggested the non- pro Migro Aray 8. Why would he suggest the 480watt version over the 520watt one?
520 cant be too much for a 4x4 right?

The usual recommendation is 35w per sq.ft. That would be 560w. Recommendations for less than that isn't in your best interests.
