Frequently Asked Questions (FAQs)

1. Do low voltage LED lights need a special transformer?

In most cases, low voltage LED lights come with a built-in driver that is suitable for powering the bulb. This means that you don't typically need a separate transformer for the LED lights.

2. How many LED lights can you put on a low voltage transformer?

A general guideline is to load a transformer up to 80% of its maximum capacity. For example, a 150 watt transformer should have a maximum load of 120 watts. If each LED light consumes 20 watts, you can comfortably connect up to 6 lights on a 150 watt transformer.

3. Do LED landscape lights require a special transformer?

If you are planning to install low voltage or 12-volt landscape lighting, you will need a special transformer designed for this purpose.

4. Can low voltage transformers be mounted outdoors?

Yes, most low-voltage transformers are designed to be mounted outdoors. They come with their own mounting systems and weather-protection seals. However, it is recommended to cover the outlet to prevent moisture from entering.

5. Can I use any 12V transformer for LED lights?

You can use a 12V magnetic transformer for LED lights, but you need to ensure that the LED strip is compatible with the transformer.

6. What type of transformer do I need for LED lights?

You do not necessarily need a special transformer for LED lights. LED lights can be used with a coil or magnetic transformer. However, it is recommended to use transformers specifically optimized for LED lights as they have lower power consumption and are designed for better compatibility.

7. What type of transformer is rated for outdoor use?

Pad Mounted Oil Filled transformers are commonly used for outdoor use in any conditions. They are industry-standard for medium voltage applications. However, for a transformer that goes from 480 to 208 volts, a dry type transformer is recommended.

8. How do you protect a transformer outside?

To protect a transformer installed outdoors, it is recommended to follow guidelines such as the NFPA 850, which recommends using a fire wall rated for 2 hours that extends vertically and horizontally. These measures help protect the transformer from fire hazards.
