Low voltage lighting operates at less than 30 volts. Power is supplied by a transformer, which itself is connected to a standard 120-volt power (commonly referred to as line voltage). The transformer steps down the line voltage to either 12 or 24 volts.
One of the biggest benefits of low voltage lighting is its energy efficiency, which helps to save the environment. Powered properly, low voltage lighting produces two-and-a-half times as much light as incandescent lamps, which run on standard line voltage. In addition, low voltage lamps have a useful life of over 10,000 hours, cutting on disposal and maintenance costs.
Low voltage lighting is safer than line voltage lighting because wiring and fixture have a fraction of voltage flowing through them, which reduces the possibility of electrical shock.
Low voltage lighting offers variety of dimming and beam control options, which allow greater customization of lighting effects to achieve desired ambiance. Fixture trim holes for low voltage lighting range from 2 to 3 inches in diameter making the lighting unobtrusive. This is especially important for large rooms that require considerable number of lights.
