lighting a 4' front to back tank (500 gallon)

[PJsStuff]

Anyone have any movies of these light movers in action? Im building a 96"x48"30" tank and i am trying to figure out the lighting. I want something thats not going to cost an arm and a leg to run each month. The LED lights are out because they just cost to dang much.

Pj light movers would make for a really boring movie. They move rather slow. Maybe a minute or so to go across the tank.

i was just wondering what the dark spots would look like. Im trying to figure out how to light my new tank. 84"x48"x30" Trying to keep the Electric bill low but i also want enough light for sps.
