A 4x4 requires a minimum 480w draw from the wall with a full spectrum modern LED for photoperiod plants . If you have a 120v power supply a 480w rated light will draw less, possibly under 380w, fine for autos.
Get a bar style light. They are far superior to anything resembling a quantum board. A detachable driver you can mount outside the tent may help with heat management. Some of the latest ones can be programmed using an app on your phone. I've used the Mars Hydro bar light and app. The app is a tad clunky to get it right but the light has lasted 9 months so far without issue and 1st class results. I've also used Spider Farmer quantum boards and bar lights without issue, same results.
The Samsung 301H EVO diodes are the bees knees when it comes to efficiency but you will get the same results from Bridgelux diodes, just your electrical bill from your lights will be about 5% more.
Those two manufacturers run some decent sales from time to time plus additional discount codes are available on line.
