Detailed Answer
Warehouse environments: indoor is relatively clean, IP65 (dust-tight and water-jet protected) basically suffices; cold storage and damp warehouses → IP67 (standard on the LDER LD series); dusty warehouses (chemicals) need IP6X at minimum. XINGJIA offers IP66–IP68 options. Match the rating to the actual environment — plain indoor warehouses only need IP65; don't over-specify.
| Indoor | IP65 |
| Cold/damp | IP67 |
| Dusty | IP6X |
Note:Match the protection rating to the environment for best value.
