Lighting Overview: Low Voltage vs. High Voltage

If you’re thinking of installing outdoor lighting or upgrading your current system, there are many things to consider, one being if you want high voltage or low voltage lighting. Since there are pros and cons to both types of systems, we’ve helped you out with this handy information below:

High voltage refers to lighting which need 120V of power to work. Sometimes also called line voltage or standard voltage, 120V are a heavier-duty system, often seen in commercial and security lighting, as well as for public use.

High Voltage – PROs

1.Lights are Bright – because of how much power they use they are perfect for large areas which need to be lit, or uplighting a large canopy of trees. This is why they are great for areas needing security lighting.

2.Fewer Fixtures Needed – because they are so bright, fewer fixtures are needed to light up an area

3.No Transformer Required – because these systems draw power right from the source, your home or business’ electrical supply, there is no need to transform the current & less of a chance that lights will dim with a voltage drop

High Voltage – CONs

1.An Electrician Is Needed – because of the high power involved all wires and connections must be installed to code, and in some cases, permits are needed

2.Higher Risk of Shock – all fittings, fixtures and connections need to be completely water tight since water and electricity don’t mix

3.Difficult to Relocate – the wires must be placed in a conduit or buried 18” below the ground not only making it more difficult to move fixtures once installed, but the installation is quite disruptive to your lawn and garden since trenches need to be dug

4.Less Beam Control – because the lights are so powerful, the beams’ spread is difficult to control and can cause problems with glare

Low voltage outdoor lighting systems use only 12V of power, making them the most common for household use and are the best option for dramatic lighting effects.

Low Voltage – PROs

1.Lower Overall Cost – the costs for fixtures, bulbs, electricity usage are all typically lower. They often have more light output per watt and therefore are more energy efficient.

2.Wide Selection of Fixtures – the choices are wide when it comes to choosing the type of fixture for your lighting needs, in both function and style. Low voltage lighting are also designed for precise lighting effects for illuminating small details of your garden.

3.Flexible – no junction boxes, conduits or deep burial are necessary making it easy to relocate fixtures if necessary. This means there is little disturbance to your lawn and gardens when installing.

4.No Electrician Required – most 12V lighting systems can be plugged directly into outdoor receptacles

5.Safer – because low voltage systems are designed for the outdoors, they operate safely under wet conditions and lessen risk of shock

Low Voltage – CONs

1.Transformer Required – because the power coming from your home is too high, a transformer is required to reduce the current to 12V.

2.Dimming May Occur – if the cable sizes aren’t the proper size, 12V lights are more prone to dimming. This could make them not the best choice for security or safety purposes.
