Best low voltage landscape lighting transformer

To install low voltage landscape lighting, you will need a transformer to reduce the 120-volt output from your home electrical system to the 12 volts used by low voltage landscape lights. You will first want to determine how many and what specific low voltage landscape lights you plan to use for your project.

What type of transformer is used for landscape lighting?

A low-voltage transformer is used for landscape lighting. It converts the line voltage (120V) to a low voltage for landscape lighting installations.

How big a transformer do you need for outdoor lighting?

You should pick a transformer rated for 25% more of the total Wattage of lights you intend to use. At the same time, avoid buying a transformer that's way too big for your chosen lights – poorly regulated transformers can damage lighting if you don't use enough bulbs.

How do I choose a landscape transformer?

Add up the wattage of each light in your landscape lighting design.
Multiply the total wattage by 1.25 to adjust for loss due to cable distance. ...
Choose a transformer that supplies no less than the required wattage and no more than 33 percent more.

What happens if a transformer is oversized?

Wattage through a transformer is governed by the load it is supporting. An oversized transformer will not appreciably use more power than several small transformers supporting the same total load.

How do I choose a low voltage transformer?

Compare your total lamp wattage to the available transformer sizes (typically 300, 600, 900 and 1200W). If you add up 600 watts, then use a 900-watt transformer. By code, transformers should be derated to 80% of their capacities so a 900W unit should be derated to 720W max (900 x . 8).

How many LED lights can you put on a 300 watt transformer?

Again, if you want to connect twenty landscape lights to a low volt transformer, and the lights are pulling 4W / 7VA / 35 Watts of halogen power draw on the system, you would need a 300 watt transformer.

How do I know what size LED transformer I need?

Take the length of your LED strip in feet and multiply it by the watts consumed per foot, then multiply by 1.2. This will give you the minimum sized power supply you'll need to run your strips.

Are all low voltage transformers the same?

There are two versions of low voltage transformers, single-tap transformers (where all outlet taps are of the same voltage, 12V or 24V) or multi-tap transformers (which include multi voltage outlet taps like 12v, 13v, 14v,15v, 16v etc).

How far can landscape lights be from transformer?

For example, put fixtures 15-30 feet away from the transformer on one run; fixtures 25-40 feet on another run; fixtures 30-50 feet on another run; and so on. The goal is to have all the fixtures on a run be roughly the same distance from the transformer so they have similar amounts of voltage drop.

How many low voltage lights can you put on a 200 watt transformer?

If each of your LED lights uses 2 watts, then the Moonray would supply enough power for 100 lights (200 divided by 2 = 100).

How far can you run 12 2 landscape wire?

Wire Gauge	Maximum Wattage	Distance the cable can run for 160W lights
12/2	240W	52 feet
10/2	300W	82 feet
8/2	480W	131 feet

How far can you run low voltage landscape lighting?

Lighting Tip: You can run 12-gauge about 100 feet without voltage drop issues as long as the total wattage of the fixtures on the wire is 100 Watts or less.

How far can I run 16 2 landscape wire?

As a guide, for 16/2 wire, you can connect up to 132 Watts as long as the cable isn't more than 100 feet. Any more than that, and you're likely to have issues with the lights not working properly.

What is the difference between 14 2 and 16 2 landscape wire?

A: 14 gauge wire is bigger/thicker than 16 gauge.. wire gets bigger as the # gauge smaller..

How do I know what size transformer to buy?

How to Size a Transformer

Transformer size is determined by the kVA of the load.
Load voltage, or secondary voltage, is the voltage needed to operate the load.
Line voltage, or primary voltage, is the voltage from the source.
Single-Phase has two lines of AC power.

What happens if you overload a low voltage transformer?

If you exceed the max amps the fuse will blow before the transformer, but don't panic, you can easily buy these fuses at home improvement stores, just make sure you buy the same size that came with the transformer and insure that it is a slow burst fuse.

What causes power loss in a transformer?

Transformer losses are produced by the electrical current flowing in the coils and the magnetic field alternating in the core. The losses associated with the coils are called the load losses, while the losses produced in the core are called no-load losses.

How many transformers do I need for LED lights?

" To work out what transformer you require this is quite simple. You take the amount of LED tape you have in metres and x this by the wattage of the LED tape you have, again per metre. For example 7m of 4.8w LED tape: 7 x 4.8w = 33.6w Therefore you would require a 60w transformer. "
