These dimmable lamp transformers are designed without noticeable hum when used with many high quality dimmers. Because of the toroidal design, these dimmable lamp transformers are more efficient and use less material than conventional transformers. Please contact us and talk to our engineers to ensure our lamp transformers work with your application.
