If you are planning on using lighting outdoors powered from your main supply it will be helpful to compare the options.
Mains voltage can differ in the number of volts across different countries; however it does need different procedures in comparison to 12 volt equipment.
Both have their advantages and if needed you can combine them for maximum advantage.
Before you consider which type of power supply you will use, it could be a very useful exercise to write up a few ideas on what you are trying to achieve and to draw out the positions of any lights you would like or think you need.
Standard Mains Lighting Standard mains supply systems can be of benefit when installing a network of lighting over a big area, or where maximum brightness is required for higher security etc.
There are also instances where you will need to cast substantial light over some distance from the light source; such as for spot lights or when using a ground set light to illuminate a large tree or building.
The nature of the installation of standard mains supply requires more stringent control over how it is installed and who carries out the work.
In many countries there are strict regulations for mains installation and this might mean you have to employ a professional electrician to do the work.
Even if you can or do carry out this work yourself, great care needs to be taken to avoid problems in the future.
The cable needed may have to be expensive and bulky armoured type for the more vulnerable positions.
Low Voltage Lighting Low voltage lights might use electricity that is provided via a transformer from your mains supply.
This means that other than the work to install the transformer and peripheral equipment; you may be able to deal with more of the work yourself, and even if you use an electrician the work could be simpler.
Modern 12 volt equipment provide more than adequate output for most requirements.
For general domestic use or smaller commercial properties 12 volt lighting could be a very efficient and cost effective solution.
Low voltage systems are very useful where you want to install a number of lights around a lawn, deck, patio or flower borders.
You might also want to set a number of lights at interval along your drive and low voltage could be very beneficial in this case.
The wiring for 12 volts can be a great deal smaller than for standard voltage as it can be safer in the event of accidental damage.
These are a few points that may help you decide which system to go for; you could also consult a professional electrician, especially if you are considering the standard voltage solution.
