Lighting Calculator Australia
Metric calculators and tables for Australian room lighting, downlight spacing, fitting counts, beam coverage, LED replacement, workplace zones and emergency-lighting records.
Most used calculators
Start with the calculator that matches the arithmetic: area to lumens, room take-off, downlight layout or operating load.
Lux to Lumens Calculator
Convert a maintained lux target and measured area into a required lumen allowance.
Room Lighting Calculator
Estimate fitting count, target lumens and connected load from room dimensions.
Downlight Spacing Calculator
Check downlight count, beam diameter and connected load before ceiling set-out.
Energy Savings Calculator
Estimate annual lighting energy, cost change and simple payback from old and new loads.
Calculation families
The full calculator set is split by job, so count, geometry, replacement, energy and workplace estimates stay separate.
Room and beam layout
Estimate room take-off, ceiling spacing and beam coverage before fixture placement is locked.
All calculatorsLED retrofit and load
Keep replacement output, operating energy and strip-driver sizing in separate records.
All calculatorsWorkplace and warehouse
Route workplace zones and high-bay areas to calculators that name task planes and assumptions.
All calculatorsHigh-use tables
Core reference tables support calculator inputs that need a unit definition, target range, beam spread or LED comparison.
Lighting Units Table
Australian English table for lux, lumens, watts, efficacy, beam angle, colour temperature, CRI and related lighting units.
Beam Angle Coverage Table
Formula-generated beam footprint diameters for common effective mounting heights and beam angles, before any delivered-lux check.
Australian Lux Level Planning Table
Conservative planning ranges for Australian rooms, work areas and circulation spaces, with AS/NZS 1680 context for technical checks.
LED Wattage Equivalent Table
Approximate old-lamp wattage, lumen output and LED load ranges for Australian lighting estimates.
Table groups
Reference pages are grouped by measurement, layout, light quality, standards context and running-load checks.
Units and maintained light
Check units, target ranges, lumen density and factor assumptions before entering calculator values.

Layout and daylight
Use geometry and daylight references when spacing, beam spread or daylight checks are the question.
All tablesLight quality and environment
Separate colour, CRI, IP language, luminaire markings and spill or glare notes.

Guides and education
Long-form pages sit behind the calculator or table they support: room planning, downlights, light quality, workplace, warehouse, outdoor and emergency records.
Guide records
Use long-form records when the job needs room notes, workplace evidence or emergency-lighting boundaries.
