Hi,
You would need to watch the evaporation like a hawk . Losing just two liters of water can make the SG raise much higher than your fish can handle. I strongly advise getting a auto top off system when running such a small setup.
As for your lighting it all depends on what you want to keep in the tank. some corals and inverts have there own needs as far as lighting go's. so research research research lol.
