There's a great budget light for 2'×2' grow areas that the YouTube channel MIGROW reviewed not too long ago called the IMVSincere BC100, if you don't want to drop 0+ on a light for a tent that's double the size of your tent.
There is a 4" gap around the outside of the light coverage that wasn't PAR checked, but the rest is great for the price.
I hope this helps.
