ABSTRACT:
A low voltage lighting system includes a transformer having at least a primary winding and a secondary winding. The low voltage lighting system also includes one or more lighting elements and a voltage control circuit. The lighting elements are coupled to the secondary winding. The voltage control circuit is electrically coupled with the primary winding. The voltage control circuit is configured to automatically increase the voltage applied to the primary winding of the transformer in a predetermined manner from a first voltage to a second voltage over a predetermined period of time.
