How it is calculated
The grid is rectangular and even. A diagonal layout, and a route around a cupboard, are not drawn here.
Spacing = (side − 2 × inset) / (count − 1)
Where the numbers come from
- Length — unit in the field: m
- Width — unit in the field: m
- Along the length — unit in the field: pcs
- Across — unit in the field: pcs
- Inset from the wall — unit in the field: m
Example
A 4×3 m room, a 4 by 3 grid, and a 0,4 m inset give 12 lights.
Questions
Is the inset more than half the room?
The calculator stops: the lights have nowhere to go.
Is this an illuminance calculation in lux?
No, only the layout geometry.
Can the inset differ along the length and the width?
No, one field covers both walls.
