If a typical system is turned on for 4 hours at ~125 W (see table below), it will use ½ kWh per night (125 W x 4 h %3D 500 Wh or ½ kWh) at an electrical cost of less than 10 cents. Low-voltage LED outdoor lighting uses 15 to 20 percent of the electricity we use with halogen or incandescent bulbs. This means much lower energy bills. These lights that operate on low voltage power consumptions are much safer to install and use, compared to other varieties of 120V lighting options.
For this system, there were a total of two riser lights (well lights of 35W each) and four path lights for the walkways (of 20W each), with a total energy consumption of 150 W. There are other ways in which a garden lighting system can be more energy efficient, which will result in significant savings when it comes to energy bills. Therefore, when you install these 12 volt LED lighting systems outdoors, these lights will not impose any risk of being electrocuted when exposed to snow or rain. Because solar luminaires don't require any electrical wiring, they're infinitely easier to install than low-voltage lights.
Outdoor lighting systems are usually low voltage (they operate on 12 volts) and consist of lighting fixtures, a transformer and an electrical cable. When designing your lighting plan, combining a variety of ornamental lighting styles is usually effective, but don't overdo it. Over the years, many homeowners have asked us how much their monthly electricity bill would increase after their garden lighting system was installed. In addition, solar powered garden lights are now an option for landscapers more focused on the environment.
More recently, some Denver townhome owners needed to share a low-voltage quartz halogen landscape lighting system to illuminate their front entrances. The house on the left (which also uses a low-voltage quartz halogen lighting system) has a total of 8 rising lights (35 W each) and 3 path lights (20 W) each, for a total of 340 W. Many modern and typical landscape lighting systems use LED bulbs, which are around 15% more efficient than old halogen or incandescent bulbs. If you are turning on landscape lighting from dusk to midnight in the state of Connecticut, that's about 5 hours a day.
