Important notes

Task lighting does not replace ambient, emergency, glare, or product-suitability review.
Useful for retail, hospitality, kitchen, and bench presets, but it does not certify compliance.

Formulas

\(\displaystyle A_{\mathrm{task}} = L \times D\)
\(\displaystyle N = \max(N_{\mathrm{lumens}}, N_{\mathrm{spacing}})\)

Estimate local task-light quantity and spacing for counters, benches, and service desks.

Counter and Bench Task 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.
