Frequently Asked Questions (FAQs)

1. What is a low voltage transformer?

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.

2. How do I choose a low voltage transformer?

The easiest way to start filtering out the right transformer is to determine if the low voltage light fixture you need to power requires 12 or 24 volts. You should be able to find this information in the description/specifications of any product. Also, determine whether your power source outputs 120 or 277 volts.

3. Do you need to change the transformer for LED lights?

They will have a transformer either in the ceiling or light fitting. Some LED bulbs, like the Philips Master LED range, have in-built circuitry that can deal with most (but not all) transformers, so you don't have to change them.

4. 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. 'LED drivers' are electronic DC power regulators designed specifically for DC LED lighting.
