Landscape Lighting Calculator is provided free of charge for planning and sizing low-voltage (12V AC) landscape lighting systems. By using this tool you agree to these terms.
This tool is provided as-is, without warranty of any kind, express or implied. Simulation results are based on the component values and circuit topology you provide. Incorrect inputs will produce incorrect outputs.
Results are for planning and informational purposes only. They are not a substitute for review by a qualified electrical engineer or licensed contractor. Always verify designs against applicable electrical codes (including NEC Article 411 and local AHJ requirements) before installation. The authors accept no liability for installations made on the basis of this tool's output.
When you use the Share feature, your plan file (including the embedded blueprint image) is stored on our server for up to 96 hours and then permanently deleted. The share link is the only access control - treat it accordingly. Do not share plans containing sensitive site information via this feature. We accept no responsibility for plans accessed by third parties who obtain your share link.
By using the simulation, you agree that an anonymized snapshot of your electrical network topology (fixture types, wire geometry, and scale) may be retained for the purpose of developing and improving network analysis algorithms. No names, labels, blueprint images, or personally identifiable information are included in these snapshots. See our Privacy Policy for details.
You may not use this service to transmit malicious content, attempt to compromise the server, or circumvent rate limits. Automated bulk use without prior written permission is prohibited.
To the maximum extent permitted by applicable law, the authors shall not be liable for any direct, indirect, incidental, or consequential damages arising from use of or inability to use this tool.
These terms may be updated at any time. Continued use of the tool after changes constitutes acceptance of the revised terms.
