Frequently Asked Questions (FAQs)

1. 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.

2. Do outdoor LED lights need a transformer?

All mains powered LED bulbs require a transformer. Depending on the bulb type, the transformer/driver may be built in to the bulb casing or may be located externally. The purpose of the transformer is to reduce mains voltage (240V) to the desired level relative to the bulb being powered (e.g. 12V or 24V).

3. 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.

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

There's no absolute maximum limit on how many lights you can add to a low voltage transformer. You can add as many as you like, providing the total Wattage doesn't exceed 80% of the capacity of the transformer.
