When applied in marine engineering, marine searchlight needs to withstand various kinds of stress for a long time, such as salt spray corros
Many marine searchlights claim to be “waterproof.”
But in real marine environments, waterproof reliability is far more complex than a simple IP rating.
Salt spray corrosion, thermal cycling, vibration, pressure changes, and long-term seal fatigue can all lead to hidden failures offshore.
In our latest engineering article, we explain:
✅ Why IP66/IP67/IP68 are only baseline tests ✅ How salt spray testing reveals corrosion risks ✅ Why thermal cycling causes seal fatigue ✅ How vibration testing simulates real ship conditions ✅ Why multi-environment validation matters for marine reliability
If you work in shipbuilding, offshore engineering, or marine equipment procurement, this is worth reading.
