Low voltage (12V) Lighting

Low voltage lighting utilizes a transformer to step the power down to 12 volt from 110 volt; the transformer is plugged into a standard wall outlet. Most transformers are approved for use indoor and outdoor. The wiring and installation method used on low voltage deck lighting is the same principle as low voltage landscape lighting. From the power source, the low voltage wiring is run in series from one light to the next, connecting all lights on one “main” low voltage wire. Connection to this main low voltage wire varies by manufacturer. Step lights, pathway lights, and accent lights can be attached to this same main low voltage wire. Installation is very easy with low voltage wire, and the majority of areas in the US do not require an electrician for installation. In addition, low voltage lighting uses relatively little power. Always size the transformer to the closest total wattage being used on the job, without exceeding the wattage of the transformer. Under-sizing the transformer will cause the furthest lights from the transformer to appear dimmer than the others. In addition, under-sizing the transformer will cause the transformer to fail. Over-sizing the transformer will cause all of the lights to appear brighter than they should be, and will reduce the bulb life. Daisy chaining, or wiring lights in series should not exceed a total lineal footage of 200’. If the application requires wire runs over 200’, see the wiring diagrams included with the transformer for different wiring options.

Line Voltage (110 Volt) Lighting

Line voltage lighting is available for posts, walkways, “brick” lights, and other landscaping applications. The most common benefit of line voltage lighting is the ability to install these lights on the same switch as other lights, thereby allowing these to be controlled from inside the house. Other applications include pool areas where 110V circuitry is available, yet an outlet may not be readily available. Power source in this environment can typically be drawn from the pump house. A drawback to 110V lighting is that it typically requires a licensed electrician to install, and many municipalities require a permit for installation.
