Important notes

Retail lighting needs merchandise vertical illuminance, glare, colour quality, emergency lighting, controls, and NCC context reviewed separately.
Use this result for early planning only, not as an Australian compliance statement.

Formulas

\(\displaystyle N_{\mathrm{ambient}} = \left\lceil \frac{E \times A}{\Phi \times UF \times MF} \right\rceil\)
Vertical shelf lighting is flagged for separate review rather than treated as a compliance result.

Estimate retail ambient fixtures, accent fixture total, power density, and vertical merchandise review prompts.

Retail Lighting Planner 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.
