Luminaire Output Worksheet Table

Planning table for keeping luminaire output, watts, optics and maintained-light assumptions traceable in Australian lighting estimates.

Lumens per watt relationshipEfficacy compares output with input power; it does not replace colour, glare or distribution checks.

Output itemWhat to captureWhy it affects the estimateBoundary
Luminaire lumensThe stated delivered lumens for the complete fitting, not only a bare lamp value.Fixture count and maintained lux estimates start from delivered output.Do not treat a published output line as the final project outcome.
Input wattsRated input power for the fitting or lighting group being compared.Watts explain connected load and energy estimates, but not brightness by themselves.Lower watts do not confirm adequate light on the assessed plane.
Optic or beam noteBeam angle, distribution, diffuser, lens or aiming note where known.The same lumen output can land differently on desks, benches, aisles or walls.This table does not replace photometric layout or glare assessment.
Colour quality fieldsCCT, CRI/Ra and any relevant colour-quality note used in the comparison.Visual comfort and colour appearance can change even when lumen totals are similar.Colour fields do not settle fitting suitability for every room or task.
Maintained-light assumptionsUtilisation factor, maintenance factor, task plane and area used with the output value.Output becomes meaningful only when the calculation assumptions are kept together.Do not mix output notes from one zone with targets from another zone.
Replacement comparisonExisting output basis, proposed output basis and any count change.Retrofit comparisons can change light level, connected load and spacing at the same time.This is a planning worksheet, not a procurement decision.
