lighting

[b-ridge]

i have a 240 gallon fowlr tank. the dimensions of my tank are 60x36x25. the problem with my tank is that it has a brace in the middle of the tank and I have overflows on each side of my tank so it can be looked at from both sides. now if i go from the overflows from each side to the middle i have 19 inches of space. if i go from front to back i am measuring 28.5 inches of space but i was told i would have to hang the lights higher so it would cover more lighting area. my question is what would you guys suggest as far as the sizing and lighting for my tank. i do plan on placing corals in my tank in the future possibly but i would also like it to run off a cycle(dusk till dawn then nighttime) i also plan on going the led way. i thank you all and welcome all suggestions and input
