Vapor Tight vs Standard Fixture Comparison
Washdown and cold rooms need a sealed luminaire, not a rugged-looking one.
"Industrial looking" is not an ingress rating. A standard fixture with a steel body and diffuser will fill with condensation in a cold room and fail in a washdown zone.
| Comparison | Option A | Option B | Winner |
|---|---|---|---|
| Ingress protection | IP65 to IP69K, gasketed body | IP20 to IP44 | Vapor tight |
| Cleaning | Pressure wash and disinfectant safe | Damp wipe only | Vapor tight |
| Materials | Polycarbonate or fibreglass, stainless clips | Powder-coated steel with a diffuser | Vapor tight |
| Condensation | Vented or sealed designs for cold rooms | Prone to internal condensation | Vapor tight |
| Cost | 20-60% higher | Baseline | Standard |
| Best fit | Food plants, car washes, cold stores | Warehouses, workshops, retail backrooms | Application-dependent |
Conclusion
Specify IP65-IP69K vapor-tight luminaires for food plants, car washes, cold stores and any zone that gets hosed down, and confirm the gasket material and clip design, not just the IP number.
