Important notes

Use luminaire output from product data and record the maintained-lighting assumptions used.
Garage and workshop electrical, glare, task, and safety requirements need qualified project review.

Formulas

\(\displaystyle N = \left\lceil \frac{E \times A}{\Phi \times UF \times MF} \right\rceil\)
Task zones are estimated separately so benches, tools, glare, shadows, and controls stay visible in planning.

Estimate ambient and bench-task fixture counts for a garage or home workshop.

Garage and Workshop 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.
