Frequently Asked Questions (FAQs)

1. Do you need a transformer for low voltage lighting?

Resources. When operating low voltage lights, you need a transformer to convert your standard line voltage (120V or 277V) into low voltage (12V or 24V). This allows your lights to function properly. If you connect low voltage lights directly to line power, the higher voltage would cause them to burn out immediately.
