Outdoor lighting transformers allow for the creation and installation of low voltage lighting systems. They efficiently and safely convert line voltage (120V current) to low voltage (12V current.
Do I need a transformer for outdoor 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.
What does a lighting transformer do?
A transformer can convert the 120v electrical currently supplied from your house down to the 12v needed for each low voltage landscape lighting fixtures in your lawn! … The benefit to having low voltage landscape lighting is two fold. First, they consume far less electricity than a “hard wire” 120v fixture.
How big a transformer do you need for outdoor lighting?
If you want to connect ten landscape lights to a magnetic transformer, and the lights use 30 watts each, you would need a 375 watt transformer. (10 lights X 30 watts = 300 watts, and 300 is 80% of 375).
How do I choose an outdoor lighting 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.
How do outdoor lighting transformers work?
Transformer: The power behind every low-voltage system is the transformer. It plugs into a GFCI-protected outdoor electrical outlet and steps down the house current from 120 volts to 12 volts. Most transformers are equipped with a 24-hour timer that allows users to decide when the lights go on and off automatically.
How many watts do I need for outdoor lighting?

What is the difference between a driver and a transformer?
Some people use the word driver and others use the word transformer. At InStyle LED they are both exactly the same thing. They are a product that transforms mains 240v down to either 12v or 24v to run the LED tape. People often use the word driver as it drives (powers) to the LED tape.
Can I use 12V transformer for LED?
FAQ – 12V Transformers and LED Compatibility. Magnetic transformers will generally work with all MR16 LED lights, albeit at the cost of efficiency and extra power consumption as was explored in this FAQ article. … They are not suitable for 12VAC (halogen or LED retrofit) lighting.
Why is outdoor lighting important?
The purpose of the outdoor lighting is to increase the effiency of human activities during the time when it is dark and to make production, transportation, construction, city beautification, etc. in the outdoor areas efficient, safe, secure and comfortable.
How do I choose a transformer?
The transformer you select must have a secondary voltage equal to the required supply voltage of the equipment, typically 120/240 VAC. 4) The Frequency in hertz (cycles per second) of the input (source) voltage must be the same as the operating frequency of the equipment being supplied.
Do LED landscape lights require a special transformer?
Most outdoor lighting systems run off of a low voltage AC transformer, usually 12VAC. … When switching to LEDs this can be a problem as LEDs need direct current, and most LED drivers are made for low DC voltage or high AC line voltage.
