The only lights of any use ,,bought at wal-mart would be 4' flourescent fixtures,,despite popular belief,do not buy "shop lite" fixture,,I know they are cheap,,but the ballast in them is only for 25w shop lite tubes,,get a good fixture that will operate 40w tubes,,,then buy cool white and warm white 40w tubes to use with it....and a heavy duty timer....that should get you started......
