AuLumens calculator library
Australian lighting calculators for practical planning checks
Estimate lux, lumens, spacing, drivers, energy use, retrofit assumptions, and documentation boundaries before you move into supplier selection or professional design review.
Calculators
Start with the calculator library
The latest tools cover maintained illuminance, residential layouts, energy cost, voltage drop, beam geometry, product checks, and planning boundaries.
Residential Lighting Zoning and Scene Planner
Summarize residential lighting zones, scene assignments, and controller group review prompts.
Vertical Illuminance Measurement Grid Planner
Estimate vertical plane measurement point counts and obstruction prompts.
Lighting Standards and Project Version Log
Track standard, product, drawing, and project changes with review status and boundary-review prompts.
Upward Light and Skyglow Pre-check
Estimate upward lumen component and skyglow review prompts from orientation context.
Commissioning Min/Max Uniformity Record
Record commissioning min/max uniformity from lux readings and explicit metric basis.
UGR Risk Screening Tool
Screen glare risk from luminaire luminance, room area, shielding records, and screen tasks.
Charts
Reference tables for common planning checks, units, assumptions, and documentation prompts.
Open chartsFormulas
Plain-language formula notes for lux, lumens, efficacy, spacing, voltage drop, and energy calculations.

New lighting guides
Short notes that explain assumptions, formula boundaries, and when a calculator should hand off to a qualified designer, electrician, supplier, or certifier.
When a Calculator Is Not a Compliance Assessment
Know when calculator output should hand off to a qualified designer, electrician, certifier, or other responsible professional.
Beam Angle, Mounting Height and Coverage
Use beam geometry to compare coverage assumptions before relying on product data or photometric files.
Downlight Spacing Checks Before Cutting Ceilings
Check spacing, clearance, cutout, and layout assumptions before installation decisions are made.
