Planner Inputs

Sets default scene ideas and comfort rules.
Example: Pathway, Patio, Greenhouse, Pond edge.
Choose how scenes trigger in the garden.
Used to estimate average lux for planning.
Total lights included in this zone.
Rated wattage at 100% output.
For outdoor path lights, 100–600 is common.
Warmer: 2200–3000K. Cooler: 4000–5000K.
Higher CRI helps plants and materials look natural.
Applied to wattage and lumen planning.
Average run time for this zone.
Use fewer days for weekend-only scenes.
Enter your local electricity price.
How much light reaches useful surfaces (0.10–0.90).
Allows for dirt, aging, and lens losses (0.40–1.00).
How many scenes to plan for this zone.
Use groups for layers: path, feature, task, safety.
Soft fades reduce glare and feel smoother.
Count sensors that can trigger or boost scenes.
Works best with motion-triggered scenes.
Example: Zigbee hub, Thread border router, Wi‑Fi bridge.

Formula used

  • Total Wattage (W) = Fixture Count × Fixture Wattage × (Dim% ÷ 100)
  • Weekly Energy (kWh) = Total Wattage × Hours/Day × Days/Week ÷ 1000
  • Monthly Energy (kWh) = Weekly Energy × 4.345
  • Monthly Cost = Monthly Energy × Energy Rate
  • Estimated Avg Lux = (Fixture Count × Lumens Each × Dim% ÷ 100 × Utilization × Maintenance) ÷ Area(m²)
These estimates are for planning. Real lux varies with mounting height, optics, reflections, and weather.

How to use this calculator

  2. Enter area, fixture count, wattage, and lumens per fixture.
  3. Set dim level and schedule to match your usage pattern.
  4. Adjust utilization and maintenance for realistic outdoor conditions.
  5. Choose scenes, groups, transitions, and sensor behavior.
  6. Press Calculate Plan to see results above the form.
  7. Export results as CSV or PDF for sharing and installation notes.
