what lighting would you use?

IMO a Radion would be way overkill for a tank this size. It's a shallow nano! You'd have to hang the Radion 5 feet above the tank to keep from cooking the livestock with photons, or keep it at the dimmest possible setting. Not a wise way to spend over $600. OPs budget is $500 or less and furthermore, he'd like something with legs. The Radion has no mounting option aside from a hanging kit that costs extra.

There are plenty of other more cost effective LED options out there for a shallow nano that won't break the bank, including diy. You might even get by with closely placed strips of 5050 or 5630 SMD LEDs that are available on eBay or other vendors in 5 meter rolls for less than $30 considering the corals you intend to start out with.

Check out some of the nano specific forums/threads to get a better idea of what's out there. Nanos were actually at the forefront of the LED revolution & there's plenty of experience to draw on there.
