20g Lighting Help

[Mozzarella]

I've decided to get into the saltwater aquarium hobby, and while I understand pretty much all the basics, I'm having trouble figuring out lighting.

My question is, what would work well for the Fusion Peninsula 20 Gallon tank with a built in sump? https://www.bulkreefsupply.com/20-fu...ve-marine.html

I plan to stock it with LPS and softies.
I would also prefer not to spend an insane amount of money. (Anywhere less than $500 would be in my budget range)
