Here are the before and after pictures.  We replaced our old flourescent fixtures with LED ceiling panels.  We removed wall scounces in favor of small LED spots in the ceiling.  We added ceiling speakers.  We used our original drop ceiling grill, but painted it with a small trim roller.  We removed the old brittle tiles and replaced them with an inexpensive flat tile above the Ceilume tiles.  The room looks great and everyone comments on the beautiful ceiling (almost as much as they comment about the new Smart TV).
