Introduction
The transformer is the backbone of your lighting system. Choosing the wrong one can lead to dim lights, failures, or burnout.
What Does a Transformer Do?
It converts 120V into 12V power for safe outdoor use.
Simplify Transformer Selection
Instead of calculating everything manually, many lighting kits already include a properly sized transformer based on the included fixtures.

How to Size Manually
- Add the total wattage of each fixture and bulb
- Add 20–30% buffer
Common Issues
- Overloading
- Voltage drop for long runs using thin wires
- Uneven lighting
Conclusion
Choosing the right transformer is critical. Using a complete lighting kit ensures all components are properly matched for optimal performance.
