Once the design and type of outdoor lighting fixture is selected, the next important question is voltage. Outdoor light fixtures are available in either 12-volt or 120-volt versions and for houses the best deal is low voltage outdoor lighting. These are easier to install as the system runs on harmless 12-volt current with light weight wiring laid on the ground or buried just below surface. The 120-volt system on other hand is same as used in interior of house and requires precautions and handling. The advantage of high voltage outdoor lighting is that it is permanent using buried conduit whereas the low voltage outdoor lighting is that is easily damaged due to superficial placement of wires.

With expenses climbing the graph we need economical trimmings. A saving advantage of low-voltage outdoor lighting is that one does not need a professional for installation. The money saved can be spent on high-quality fixtures and landscaping. Some low voltage light fixtures work on solar energy and once charged work when sensors activate the lights on sunset.

Another advantage of low voltage outdoor lighting is that smaller and compact fixtures are flexible and can be activated by timers, motion detection or switches. This is an advantage as compared with high or regular voltage lighting fixtures that require conduits and labor to fix wiring. The size and design of low voltage outdoor lighting fixtures help add to the aesthetics of surrounding. The reason they can be safely hidden or placed in nooks and corners, waterfalls, bushes or exterior of buildings and residences. The drawback is that to highlight a particular area more fixtures are needed. Quality also matters in that if inexpensive crack and corrode due to extreme temperature or corrosion. The inconvenience ends here as low voltage outdoor lighting once installed requires minimum attention. Nevertheless a perfectionist or cleanliness freak would like to coat sockets with silicon - based lubricants once a year, clean accumulating debris in up-lifting fixtures and replace dead lamps to avoid unused voltage.

Low voltage outdoor lighting is aesthetically safe, economical and energy efficient with performance comparable to a 120 volt system.
