Important notes

Define the task plane and verify the luminaire output, beam distribution, and installation position against the product data.
Australian residential guidance and any AS/NZS 1680 application require current, task-specific review; this result is not an automatic compliance claim.

Formulas

\(\displaystyle A_{\mathrm{task}} = L_{\mathrm{bench}} \times W_{\mathrm{bench}}\)
\(\displaystyle \Phi_{\mathrm{task}} = \frac{E_{\mathrm{task}} \times A_{\mathrm{task}}}{UF \times MF}\)
Bench shadows, cabinet overhangs, reflectance, glare, and island-specific lighting need separate review.

Estimate ambient and bench-task lighting quantities for a kitchen.

Kitchen 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.
