lighting needed for a 15gallon Nano?

The highest temp that I have seen in my tank when it was a fresh setup was around 27 degrees celsius so with the fixture on I don't think I will have to worry all that much.

You can see my smaller computer fan here on the top left. It worked awesome. I could even touch the glass top without it burning me. I then upgraded to an actual tank mounted one that looked better.

Ahhh!! I can't wait till my tank looks like that. I'm aspiring to have a nano aa great as yours fishy.

So I have looked up some pricing on line and have read a little more on keeping SW nano tanks and I have decided that I may up grade to a :

12-1/2"L x 30-1/4"W x 13"H
24" 298W Metal Halide System Extendable Series
JBJ OCEANSTREAM OS101 - CIRCULATION PUMP 500 GPH

with my existing Fluval E series 50W heater, my koralia nano 240 gph power head and fuge modded ac110
Im just curious as to if this will be enough light and flow for the tank if I upgrade slightly, and I kinda just need a bit more wiggle room so i have a bit more dilution on my side

265 $ setback, little longer for the lights such a shame.
