Delivers beautiful and vibrant 4000k colors. But it buzzes annoyingly. If you have a group of people talking, you won't notice. However, if there is no other sound, it is definitely audible. Return it and pay more for Philips; never let me down. (Tried generics including Hyperkinon, Great Eagle, and Sunco. None of these come close to 4,000,000 colors or better than GE and Philips.)
