Important notes

Use luminaire/system output from the product data, not bare-lamp lumens.
Australian residential guidance and any AS/NZS 1680 application require current, task-specific review; this result is not an automatic compliance claim.

Formulas

\(\displaystyle A = L \times W\)
\(\displaystyle \Phi = \frac{E \times A}{UF \times MF}\)
Zone and spacing outputs are planning estimates; furniture, optics, glare, controls, and product data need separate review.

Estimate ambient and accent lighting quantities for a living room from room dimensions and planning assumptions.

Living Room 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.
