A Primer On Safe And Economical Outdoor Lighting
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.
Electrical voltage above a 60 – 70 volt threshold is sensible to humans. Above 100 volts it becomes dangerous. At just 12 volts, low voltage electricity is safe because it cannot cause electrocution. So outdoor lighting systems using low voltage electricity are absolutely safe.
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.
So just how much money can you save with LED lamps? Well consider that they typically use about a quarter of the electricity of standard lamps. That’s a 75% savings every month on your outdoor lighting bill. Figure that out over the course of a year or even ten years, and the numbers become significant. Then when you add in the fact that these bulbs will last at least 10 times longer, the savings get even better. And as an added benefit you won’t be forced to change the bulbs nearly as often. As we all know, outdoor lights always seem to go out when we would least like them to, like when the temperatures are sub-freezing.
The current load for LEDs is so low that you can use light wiring for the low voltage outdoor lighting system. You can use overhead wiring without fear of it causing grievous bodily harm to people or animals. With light overhead wiring it is easy to rearrange the lighting whenever required. This allows you to highlight different parts of the house and grounds for a change. So you can highlight the gazebo one month, and the Spanish columns the next.
Changing your outdoor lighting system to a low voltage outdoor lighting system using LED lamps will be a power and money saving idea. You’ll be contributing to environmental conservation as well by reducing the demand on large power generating stations. The main benefit of a low voltage outdoor lighting system is that you are now completely free from the risk of electrocution accidents. You can watch your children play out there and not have the teeniest fear about them getting a fatal shock. What could be better than that?
