Your Complete Outdoor Lighting Solution
Outdoor low voltage lighting has been a growing trend across the United States. Landscape designers, contractors, and installers are looking to include Tru-Scapes® professional lighting solutions.
What Size Transformer Do I Need?
Choosing the correct transformer is one of the most important steps when designing and installing a low voltage outdoor LED lighting system. A properly sized transformer ensures your lights perform correctly, maintain consistent brightness, and operate safely for years to come.
All Tru-Scapes transformers operate on low voltage AC power and are designed for professional-grade outdoor LED lighting systems — delivering reliable performance season after season.
Calculate Total Wattage
Start by adding together the wattage of every fixture connected to the transformer.
Add Capacity Headroom
For best performance and long-term reliability, we recommend loading transformers to approximately 70–80% maximum capacity. This allows room for:
- ✓ Voltage fluctuations
- ✓ Future fixture additions
- ✓ Longer wire runs
- ✓ Cooler transformer operation
- ✓ Improved LED performance and lifespan
Find Your Perfect Match
Use these charts and recommendations to choose the right transformer, wire, and zone setup for your outdoor lighting project.
Recommended Transformer Sizing
Match your total fixture wattage to the right transformer size.
| Total Fixture Wattage | Recommended Transformer |
|---|---|
| 1–70 Watts | 100 Watt Transformer |
| 71–160 Watts | 200 Watt Transformer |
| 161–320 Watts | 400 Watt Transformer |
Recommended Wire Size
Tru-Scapes recommends a minimum of 12/2 low voltage direct burial wire for outdoor LED lighting installations. Using larger gauge wire helps reduce voltage drop, improves system performance, and allows for longer wire runs.
- ✓ 12/2 wire recommended for most residential installs
- ✓ Larger systems may require heavier gauge wire
- ✓ Avoid undersized wire to prevent dimming & voltage loss
Understanding Zones on a Transformer
Our 400 watt transformer includes 2 separate zones. This allows contractors and homeowners to:
- ✓ Separate front and backyard lighting
- ✓ Divide larger systems into multiple wire runs
- ✓ Reduce voltage drop
- ✓ Simplify troubleshooting and maintenance
Why Proper Transformer Sizing Matters
