Definition
Warehouse lighting requires 150-300 lux for general storage (IES RP-7), 300-500 lux for picking/packing zones where label reading and detail work occur. The lumen method calculation: Total lumens = Target lux × Area (m²) ÷ (Utilization Factor × Light Loss Factor). For a 1,000m² warehouse at 200 lux with UF=0.6, LLF=0.7: Required lumens = 200 × 1,000 ÷ 0.42 = 476,190 lm. At 140 lm/W, that's 3,400W of LED power — approximately 17 UFO high bays at 200W each.
Key Data
| Parameter | Value / Explanation |
|---|---|
| General storage | 150-200 lux — crate/box handling, no fine detail |
| Picking/packing | 300-500 lux — label reading, barcode scanning |
| Loading dock | 150-300 lux — transition zone, safety critical |
| Uniformity | Emin/Eavg ≥0.4 minimum; ≥0.6 for picking zones |
Application Guide
E-commerce warehouse
300 lux, CRI 80+, UFO high bay 200W, 90°
Picking accuracy depends on adequate illumination
Conclusion & Procurement Recommendation
Specify maintained lux per zone, not a single number for the entire warehouse. Picking/packing zones need 2× the light of storage aisles. Use lighting controls to dim storage aisles when unoccupied (40-60% additional energy savings).
