The closest to your budget lighting from the upper tier/super high quality lights are these:
This LED light fixture features Bridgelux Vero29 COBs and a Meanwell driver. Remote driver placement helps with managing heat and custom color temperatures are available. Innovative design for covering up to 6 square feet and small grow areas.

This would be the minimum amount of wattage I would suggest in your 7 sq ft tent. 210 watts of high quality cobs gives you 30 watts per square foot. The fixture is completely assembled and ready to go. Just plug it in. $279

This quantum board light is not their newest design, but is still very good. 260 watts is 37 watts per sq ft for you, which may even be more than you actually need but the light is dimmable if you needed to turn it down. Keep in mind I am running 285 watts of qb's in my 6 sq ft with no problems. This is a kit which requires a few minutes for you to assemble. $279
IMHO, those are the best lights from reputable companies that will be around if there is ever a problem. If you can afford either of them, I would do that. Other options include building your own light using led strips, cobs, or quantum boards. This may require you to do some learnin' to understand how to design and build your own -- but this isn't rocket science. Maybe contact
@CobKits for some ideas if you decide to DIY.
You can also look into Chinese lights that are knockoffs of quantum boards fixtures, but keep in mind they probably are not exactly what they claim they are and they will ghost you if you contact them if something goes wrong with your light.
Unfortunately, quality costs money. Buy once, cry once.
