Halogen to LED Savings Calculator
Compare an existing halogen system with an LED retrofit: energy, cost and lamp replacements per year.
Color Temperature Explorer
Slide from candle-warm 2200K to cool 5000K and see which light color flatters brick, stone, foliage and water.
Sunset & Timer Planner
Month-by-month sunset times for Spring, TX, with suggested timer settings and yearly run-hours.
Estimates are a starting point
Our tools use the same rules of thumb designers start with: fixture spacing, the 80% transformer rule, wire resistance and real sunset data for Spring, Texas.
A real lighting plan responds to things a calculator cannot see: your home's materials, the exact shape of your trees, where you sit on the patio, and what your neighbors see. That is why Spring Landscape Lighting finishes every installation with a nighttime adjustment.
System details
Planning estimate only. Transformer losses, dimming, voltage drop and billing structure affect real usage.
