*Formula: 22 × 20 ft = 440 sq ft; × 50 = 22,000 source lumens; ÷ 5,000 and rounded up = 5 fixtures. The 35/50/65 presets are editorial scenarios, not prescribed illuminance standards. This does not calculate lux or foot-candles at the work surface, losses, circuit capacity, spacing, or glare. Verify photometric and installation data for the actual room.
