new 45

I have a 45 gallon tank with dimensions 48"L×12"W×18"H and would love some recommendations on a budget build. Plan for the tank is to have a mixed reef tank with other fish and cleanup crew. The main focus of this would be the best budget light I can use for this tank, preferably sub $200...

( Note the picture is not final layout or placement, just a temporary spot til i find the right home) I've decided to start my first Salt Water build after a couple years of fresh water! I'm planning on taking it pretty slow setting up, but am almost ready with the initial items for the setup...
