I like the lights lower, close to the water and I also prefer a tight-fitting lid. I never needed to top-off to replace evaporation, even in hot weather. If you get the lights close you really need some sort of cover to keep the water out of the electronics. Even if the fish don't jump, they can splash, and the condensation around electrical fittings is a bad story waiting to be written.
I use a lexan cover that I had a glass store cut for me. It isn't breakable, can be cut in any shape, transmits light better than glass, and is very light. The downside is that it can be scratched and ammonia (windex) would glaze it.
If you have something enclosed you'll also be better off with a fan to keep it cool. Just my $0.05.
