I recently read about much different ballasts can affect the actual color output of bulbs. The film industry and aquarium geeks have had issue with this. I'm hoping that my cheap Walmart and Sunpark ballasts don't change the specs of the tubes I'm getting too much. I really don't have the cash to lay out on the killer DMX color controllers that studios use.
