Meeting Room Presentation Wall Lighting Calculator Australia

Estimate vertical light, fitting count and load for a meeting-room presentation wall.

Presentation wall

Wall size, target and fitting data

Estimate vertical light for one presentation wall or whiteboard surface.

Width of the desk row, counter, wall, mirror, shelf face or target surface.

Height of the vertical face, wall, mirror or presentation surface.

Maintained lux target for the task or workplane.

Published output for one luminaire.

Input power for one luminaire.

Conservative allowance for light reaching the vertical target face.

Allowance for ageing, dirt and lumen depreciation.

Distance from the light source to the target surface along the aimed path.

Published beam angle for the fitting.

Formula

surface area = width x height; required lumens = surface area x target lux / (vertical UF x MF); beam diameter = 2 x throw x tan(beam angle / 2)

Vertical surface area x target lux is adjusted by vertical utilisation and maintenance factors, then divided by fitting output.

VariableTechnical meaningDesign check
Surface areaWidth multiplied by height.Use the visible vertical target.
Vertical allowanceVUF and maintenance factor applied to fitting output.Keep the assumption visible.
Fitting countRequired vertical lumens divided by one fitting output.Rounded up to whole fittings.
Optional beamThrow and beam angle describe coverage only.No glare review or sign-off result.
BoundaryVertical planning estimateNo formal assessment or sign-off result.
