When you think of outdoor lighting you think of floodlights to light up the house and its environs in the night for safety and security. You may also think of decorative lighting for the garden. Then there is highlighting to show off your landscaping or architectural beauty. In all these cases the outdoor lighting involves running wires carrying high voltage to the different light points. You may run the wires underground or overhead. However you run the wiring, you have to be very careful that there is no chance of electrocution. Underground wiring is prone to water infiltration and damage by normal activities like gardening or some sports (cricket, for instance). If the insulation of underground wiring is damaged, high voltage electricity can leak out. Overhead wiring can break in storms and fall to the ground. Fatal accidents can occur to human or animal victims. Electrical short circuits can cause fires to break out, injuring people and damaging property. If you are thinking of rewiring your current outdoor lighting system, or if you are planning to install one for the first time, you should opt for the low voltage solution.
The concept behind the modern outdoor lighting system is straightforward and simple. You replace the traditional lighting system which utilizes high voltage circuitry operating at 120 volts with a modern lighting system operating at a low 12 volts. Some systems use 24 volts. Whichever voltage is chosen, these low voltages pose no threat at all to life or limb or property.
The outdoor lighting system is supplied low voltage electrical power by a transformer that steps down the high voltage of 120 volts from the mains supply to a safe and low 12 volts. Some outdoor lighting systems run on DC which means that they can be run even when the mains fails. Low voltage lamps are available in the market. You can choose incandescent lamps if you like. But incandescent lamps are very energy-hungry. It is better that you go in for high efficiency lamps like the latest LED lamps that have just appeared on the market at affordable rates. LED lamps consume just one-fourth of the electricity consumed by incandescent lamps with a comparable light output.
The installation of a modern outdoor lighting system is quite simple, mainly because lethal voltages are not involved. If you are conversant with electricity and electrical circuits, you can manage the installation yourself in an easy one-day job. You don’t need any kind of special equipment or tools to install the low voltage system – no insulated gloves and no delicate measuring equipment. Be warned, however, that short circuits can still cause fires, so be very careful to use fuses or the modern miniature circuit breakers (MCBs) of appropriate rating at strategic junctures. You can afford to use high quality cable and MCBs because the overall saving you make by implementing this system is much more than the cable cost.
But getting back to the cost effectiveness for a second, consider the fact that an LED lamp uses only about 25% of the electricity of a standard lamp. How much difference would that make on your utility bill every month. Figure out those saving annually and that’s quite a bit of extra money in your pocket. And it gets even better. LED laps will last at least ten times longer than a normal incandescent lamp or even fluorescent lamps. So you’ll save money there also. Plus you won’t have the hassle of having to frequently change the bulbs.
The wiring for low voltage outdoor lighting need not be buried underground. Because the load of LED lamps is so low, the wiring is commensurately light. This means that you can change the wiring around quite easily whenever you feel the need for a change (of outdoor lighting, that is). This is a very handy feature when your house has many special features. Highlighting them all at once is garish, and that defeats the very definition of highlighting! So one month you can highlight the gable roofing, the next month the side elevation, and the colonial columns the following month. The same applies to the landscaping or wooded area around the house.
This primer on low voltage outdoor lighting should encourage you to change over to a modern efficient lighting system for your outdoor lighting needs. You’ll save pots of money in electricity bills, take my word for it! More importantly, you’ll be 100% free of electrical shock hazard. Your householder’s insurance cover will benefit too, from the changeover. This means that the value of your house will go up while you are actually saving money. Now aren’t you glad you read this primer?
