How lumen planning works
50 lm/sqft budget, class matching, and light safety.
Job-site lumen planning
LED work light size by floor area
Enter floor area in sq ft. Get a 10k / 15k / 21k lumen class or NO_MATCH. Planning budget uses 50 lm/sqft — not a photometric layout. Confirm lumens, aim, and GFCI outdoors.
Job-site lumen planning
Result
Match the smallest class where class.lm ≥ area_sqft × 50. Classes: 10,000 · 15,000 · 21,000 lm. Above 21,000 lm budget → NO_MATCH. Planning screen only (≈50 lm/sqft), not a photometric layout.
