Important notes

Check services, structure, furniture, access panels, and the luminaire photometric file before installation.
Australian standards may inform the planning boundary; this calculator does not certify compliance.

Formulas

\(\displaystyle n_x = \lceil(L-2O_x)/S_x\rceil + 1\)
\(\displaystyle x_i = O_x + i(L-2O_x)/(n_x-1)\)
Coordinates are a geometric planning model; optical performance requires separate review.

Generate a regular row-and-column lighting layout with edge offsets and forbidden zones.

Regular Grid Lighting Layout Calculator is a planning aid. Keep the target source, product data, measurement method, and project assumptions with the result. Confirm compliance, installation, certification, and safety decisions with the responsible professional.
