Lighting comparisons
Decision-support comparisons for lighting output, appearance, distribution and exposure terms before a calculator or table owns the number.
LED vs Halogen
Compare output, load and operating cost after a halogen swap.
Lux to Lumens vs Lumens to Lux
Choose the right calculator path for target-light allowances, known-output checks and Australian lighting records.
Warm White vs Cool White
Compare warm, neutral and cool white lighting by appearance, task visibility and room context.
Colour Temperature vs CRI
Separate white-light appearance from colour rendering so Australian lighting records do not confuse CCT with CRI/Ra.
IP44 vs IP65 for Lighting
Compare splash-resistant and jet-resistant IP ratings for lighting exposure notes.
Downlight vs Panel Light
Compare downlights and panel lights by distribution, task plane, glare, ceiling set-out and Australian lighting calculation path.
Lamp and load changes
Retrofit checks where output, connected load and annual energy need separate records.
Calculation direction
Choose the calculator path before a target-light allowance, known-output check or measured-light comparison is entered.
Colour appearance
CCT, colour-rendering evidence and surface appearance before warm, neutral or cool white assumptions are locked.
Fitting type and distribution
Distribution, glare and set-out differences for downlights, panels and room lighting records.
Protection rating
IP44 and IP65 language for wet-area-adjacent, exterior and luminaire-marking notes.
