A luminaire is the complete lighting fitting used in a lighting calculation.
A luminaire is the complete light fitting or lighting unit. In calculations, use the published output and input data for the complete fitting where available.
Technical meaning
A luminaire is the complete lighting fitting or lighting unit, including the optical, mechanical and electrical parts supplied as that unit.
For calculator inputs, complete-luminaire lumens and watts are usually more relevant than bare lamp or LED package values.
Calculation use
Fixture-count and room estimates divide the required lumen allowance by the published lumen output for one luminaire.
Connected-load and energy estimates use the input watts for the complete luminaire or luminaire-driver combination.
Not the same as
A luminaire is not just the lamp or LED chip. Optics, housing, diffuser and driver losses can change usable output.
A luminaire entry is not an installation approval. Markings, location, controls, wiring and maintenance context still need separate checks.
Australian context
Australian lighting schedules should keep luminaire output, input watts, CCT, CRI, IP marking and driver or dimming notes traceable to the selected fitting data.
Examples
Example
Value
Planning note
Downlight
900 lm, 10 W luminaire
Use fitting-level output for count and lux estimates.
Panel light
3,600 lm, 36 W luminaire
Note output and load separately from colour and glare notes.
High-bay
20,000 lm luminaire
Beam distribution and mounting height still decide the assessed-plane result.
Luminaire definitions and markings support calculator inputs. Fitting selection, installation suitability and regulated project use require current fitting data and project evidence.
