| Output item | What to capture | Why it affects the estimate | Boundary |
|---|---|---|---|
| Luminaire lumens | The 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 watts | Rated 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 note | Beam 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 fields | CCT, 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 assumptions | Utilisation 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 comparison | Existing 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. |
