A low voltage transformer is at the heart of every landscape lighting system. It converts 120 volt current to a low voltage current (between 12-15 VAC). The efficiency of this conversion determines how well the transformer controls the voltage output and how much energy is consumed in the process.
What is a low voltage transformer used for?
Low voltage transformers are commonly used for low voltage lighting, which typically only uses 12 or 24 volts. There are also many low voltage transformers to meet the needs of defense, manufacturing, medical care and research industries.
What is a good low voltage transformer?

Do I need a transformer for landscape lighting?
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. Remember that you may want to leave room on the transformer to add additional fixtures in the future.
Do all low voltage transformers work with LED lights?
No, low voltage AC lighting is not just used in landscape lighting to try and spite all those switching to LEDs. It was actually used in many old systems as it was much easier to create a 12VAC transformer compared to a DC transformer and incandescent bulbs could care less about AC or DC power.
Do you need a special transformer for LED landscape lights?
In the world of low voltage landscape lighting, LED lamps have also become prevalent. In fact, they have allowed us to create larger lighting systems, often, without the need for larger transformers.
What is one advantage of using a voltage transformer?
Low voltage transformers are useful in society since they reduce the chances of humans suffering an electric shock. They help keep electrical environments safe in both residential and commercial structures. High voltage transformers are useful for supplying powerful equipment energy.
Can low voltage transformers be mounted outdoors?
Most low-voltage transformers have their own mounting systems, so you can attach them to stakes outside your home. These transformers also have weather-protection seals, but it’s still a good idea to cover your outlet to keep moisture out.
What is the difference between indoor and outdoor transformer?
What is an indoor and outdoor substation? The substation which installs for low voltage requirements inside the building construction is called an indoor substation. The substation which installs for high voltage requirements outside the building construction is called an outdoor substation.
How long do low voltage transformers last?
They operate at about 90 to 95 percent efficiency and can run for a very long time, anywhere from 20 to 25 years.
Why do outdoor lights need a transformer?
The transformer is the main component for distributing safe voltage to all of your landscape lights. Each transformer consists of many electronic components that work together to step down your home’s 120V system down to the 12V needed to power your landscape lights.
What happens if you overload a low voltage transformer?
The transformer can’t cause damage to the power outlet. The overload transformer’s voltage would drop. The domestic plug’s voltage would be low.
Can you hardwire a low voltage transformer?
To hardwire a low voltage transformer, the main power should be turned off at the breaker panel before making any electrical connections. The polarity of these wires is not important; either wire on the output side of the transformer may be connected to either wire of the low voltage circuit.
What is the difference between a transformer and a LED driver?
A transformer converts AC to AC; e.g., 240V AC to 12V AC. An LED driver typically supplies a constant current (e.g, 150mA DC) to a fairly-low voltage load (e.g., 36V DC; 12x 3V series LEDs, probably paralleled), while being powered by a high-voltage (e.g., 240V AC) input.
Can you connect string lights to low voltage transformer?
Answer: Yes, you can. this low voltage string lights can be connect to your low voltage lighting system, transformer, off-grid or solar lighting system with the US plug line.
Can I use a 12V halogen transformer for LED lights?
Existing transformers typically used with halogen spotlights can usually be used however there is one problem. Since the transformer expects one or more 30+ Watt bulbs to be connected to it, the voltage output when a few 1 Watt LED spotlights are connected can exceed the transformer’s 12V rating.
Can you use any transformer for LED lights?
Yes. Multiple LED strip lights may be powered through a single LED transformer as long as care is taken to ensure that the total wattage demanded by the strips does not exceed the electrical load limits of the transformer.
How do I choose a transformer?
To select the proper transformer, determine the input and output voltages, frequency and current. The faster the voltage changes, the higher the frequency. The higher the current, the more heat is produced.
How far can you run low voltage LED 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.
What are the disadvantages of a transformer?
Disadvantages of transformer : A transformer will not work with DC voltage under any condition. The transformer size become un widely. The physical size of the transformer is directly related to the amount of power to be desired. It is not good to use outdoors. It can be noisy.
