You can go Halide lighting which has great light penetration!! I like 14kelvins bulbs IMO there just the perfect combination!! But honestly lighting, Skimmer, return pump and heater Are four things that shouldn't be skimped!! IMO.
If lights can't penetrate your water efficiently corals and nems that depend on light may die or won't grow.
If the skimmer is a cheep one, excess Nutrients will build and cause headaches.
If the return pump fails either sump overflows or it will overheat and cause a crash.
And if the heater fails it will kill everything in your reef wether it be not functioning or overheats.
hope that helps!! Not to scare you or anything just made those mistakes in the past and would hate it to happen to anybody else!!
