Frequently Asked Questions
What is the difference between 12V and 15V output on a transformer?
A 15V output compensates for voltage drop over long wire runs ensuring lights remain bright. A 12V output is standard for shorter runs and most landscape fixtures.
Do these transformers work with LED lights?
Most modern transformers are compatible with LED fixtures. Check the manual to ensure your specific LEDs work with the transformer's output type and voltage.
How do I prevent voltage drop in my landscape lighting?
Use thicker wires and multi-tap transformers to adjust voltage. Keep wire runs under 100 feet and space fixtures evenly to minimize drop.
Can I use a 300W transformer for indoor lighting?
While some transformers have indoor options they are generally designed for outdoor use. Check the listing to confirm if indoor installation is safe and supported.
Why does my transformer keep tripping the breaker?
Tripping indicates an overload or short circuit. Reduce the number of lights or check wiring for faults. Replace the transformer if issues persist.
