Earth Conscious Apps introduces the Landscape Lighting Calculator, easy electrical calculators and tutorials that assist architectural and landscape lighting installers in creating an efficient lighting system at lower installation costs while increasing long-term safety. The calculators are customized specifically for 12V – 24V low voltage electrical systems that are commonly used for LED and halogen outdoor lighting (with a focus on 15V for LED). The calculators are also extremely effective at troubleshooting installation issues!

Over eight years of field testing in the landscape lighting industry!

Landscape Lighting Calculator includes:

Calculator: Minimum Wire Gauge
Calculate the Minimum Wire Gauge needed for a run based on: Wattage, Length of Run and Voltage.

Calculator: Minimum Transformer Size
Calculate the Minimum Size of Transformer that you need for your landscape lighting system, including total watts of the installation. This calculator also verifies each run for wire gauge and length of run.

Calculator: Maximum Available Wattage
Calculate the Maximum Wattage you can put on a give Gauge Wire, Voltage Tap and Length of Run. This calculator is helpful if you already have a certain gauge wire and want to know how many and what wattage lights can be used on the wire.

Calculator: Maximum Distance
Calculate how far you can go with a given Wire Gauge, Voltage Tap and Wattage. This calculator is also helpful if you already have a certain gauge wire and want to know how far you can go with a given wattage and voltage.

Tutorial: How to Use
How to use each calculator to get the best results.

Tutorial: Getting Started
Step by step guide to creating an organized lighting plan, including: where to locate the transformer, how to group lights for efficiency, and tips on how to future proof your landscape lighting system.

Tutorial: Wiring Basics
In this tutorial you will learn wiring and connection basics, how to look up National Electrical Code installation requirements, and where to get more detailed information if you are curious.

Tutorial: VA vs W (Volt-Amperes vs Watts)
Learn the difference between VA (Volt-Amperes) and W (Watts) and how to use these correctly in the calculators.

Doesn't matter what wire or things I put keep saying the same thing. Worthless app

Not Happy

Can’t get the transformer calcs to reset- tried everything 33 times- wouldn’t reset to zero runs no matter how many times I hit reset- sorry, can’t say anything else but “lame.”
