Flood vs High Bay Comparison
Outdoor vs indoor distribution patterns.
Floodlights throw light forward along walls and yards; high bays throw it down from a ceiling. The difference is distribution, mounting and ingress protection rather than raw lumen output.
| Comparison | Option A | Option B | Winner |
|---|---|---|---|
| Optics | Wide/asymmetric | Circular/wide | Application-dependent |
| IP rating | IP65-IP66 | IP54-IP65 | Application-dependent |
| Mounting | Wall/pole | Ceiling truss | Application-dependent |
| Best for | Yards, facades | Warehouses | Application-dependent |
Conclusion
Use floods on walls, poles and façades where light must travel horizontally, with IP65-IP66 as standard. Use high bays under a roof where the target is the floor and uniformity across the aisle is the metric.
