This is a listing on ebay from the company I got the light from. There are 2 2X4 LED panels for that price. I ended up calling them on the phone because I needed to be sure I was sent the correct hanging fixture.
Home Depot has had several sized LED panels on closeout this week...perhaps making space for next year's model? I think I saw 1' x 1', 2' x 2', and 4' x 2'. I couldn't tell you anything about the actual light characteristics, but might be worth a look if you are looking for a bargain. I think I saw one display (may or may not be the same panels that are on closeout) that featured a panel being used to illuminate a billiards table in the display pic.
Mark Gregory makes them to match your table. I'm the other guy that has the Rosewood centennial from Mark. He made me a matching LED light that is fantastic. He's coming to Dallas again in a couple months if you want one. Here is a pic of mine;
