Need recommendation for 72" 300 gallon lighting

[Racersk]

I need a basic light for a 300G 3'x6' tank. I would like to keep the lumens down, no plants, just fish. Algae is a concern. I have a LED shop light now, but want something that does not lay on the glass. Like a rim mount or a full 7" light. Any suggestions?

I also put a 48 inch on on my 90g:
