What does an LED light transformer do?

LED transformers are capable of controlling a greater flow of electrical power. Transformers therefore provide the ‘heavy-lifting’ power supply solution for larger scale LED lighting projects such as strip lighting (also known as ‘LED tape’).

What does a transformer do for outdoor lighting?

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.

Do transformers work with AC or DC?

Transformers do not pass direct current (DC), and can be used to take the DC voltage (the constant voltage) out of a signal while keeping the part that changes (the AC voltage). In the electrical grid transformers are key to changing the voltages to reduce how much energy is lost in electrical transmission.

Do LED lights require transformers?

LED drivers function. In other words, long-length strips of LED lights may require a power supply in excess of 200 W, and since LED drivers may be limited in power output to 100 or 200 W, an electronic transformer may be needed.

What is the difference between a transformer and an 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.

What are the two main types of transformer?

Transformers generally have one of two types of cores: Core Type and Shell Type. These two types are distinguished from each other by the manner in which the primary and secondary coils are place around the steel core.

Do garden lights need a transformer?

As our system runs on 12 volts, a transformer is needed to supply the lighting with power. Before you select a transformer, it is important to know the total wattage of the lamps you want to install in your garden.

How do you know if a light needs a transformer?

So how do you tell if you need to change the transformers? One way is to look at your old halogen bulbs and see if they have pins or pegs to plug them into the power circuit. Basically, pins need a new transformer and pegs do not. But it’s generally a good idea to install an LED driver regardless.
