Technical meaning
- Task lighting is directed or local light for work such as reading, food preparation, bench work, inspection or display viewing.
- The useful result belongs to a named task plane, not to the whole room label.
Calculation use
- Lux-to-lumens and room-lighting estimates should separate a task zone when its target differs from the ambient room target.
- Colour temperature, CRI/Ra, glare and control state can matter more for task lighting than for background ambience.
Not the same as
- Task lighting is not a shortcut for raising every room surface to the same target.
- A task light is not electrical installation advice or a fitting-selection instruction.
Australian context
- Australian home-office, kitchen, workshop and retail notes should name the task plane before comparing local lighting with ambient room lighting.
Examples
| Example | Value | Planning note |
|---|
| Kitchen bench | local task layer | Note shadows from cabinets and the bench surface, not only the room area. |
|---|
| Home office desk | desk plane | Screen direction and daylight side can change comfort. |
|---|
| Workshop bench | high-detail surface | The bench can need a different note from the surrounding garage. |

Calculation limits and records
- Task-lighting notes support local calculation evidence. Suitability still depends on the task, surface, fitting data, controls and project context.
