Different Types of Low Voltage Lighting Installations

Low voltage LED landscape lighting fixtures are a great solution to many of the problems that other landscape lighting systems cause. For one, they are shock proof, so all that is required is a transformer, not a professional installer along with long cables, deep trenches, and electrocution worries that regular lighting systems may cause.

Low voltage lighting is also incredibly reliable, so you won’t have to worry about a cloudy day or shade like you do with solar lighting systems. If you’re thinking about installing a low voltage lighting system yourself, here are some different installation methods that you can use.

The first and most common type of installation for a low voltage lighting system is a straight run. This runs the power cable straight away from the transformer and then you place light fixtures along it as you go. It’s by far the easiest way to install your lighting system, but it also can run into problems with voltage drop. Because there is the minimum amount of voltage in the line with this type of installation, even the loss of a little bit of voltage will make the lights at the end of the run dimmer than those at the beginning. There are three main ways to get around this problem.

The first way is by installing a loop. Loop installations reduce voltage drop, but you also need to take care in installing them. Always make sure that you don’t cross the wires or you could be in for a nasty surprise! And a new transformer, if the one you’re using blows. Another option is to buy a multi-tap transformer. Multi-tap transformers let you run several lights to different areas of the yard, so you can make several straight or loop runs. This puts less light fixtures, and therefore less pressure, on each line. Finally, you can do a T-line installation. T-line low voltage installations consist of a larger wire that feeds several smaller wires. This method requires a little bit more caution in installation, but it is a great option for homes where there’s almost no way to put a transformer close to your lights.

When it comes to installing low voltage lighting systems or kits, there are a number of options so that you can find just the right one to meet your specific lighting and placement needs. No matter which installation option you go with, however, the process is far simpler than running other electrical lighting and the outcomes are more consistent than those offered by solar lighting.
