IP65 ≠ Rainy Season Safety

What does IP65 represent?
Dustproof + resistance to low-pressure water jets. This is a laboratory testing standard. But the real rainy season involves: torrential rain + high temperatures + day-night temperature differences + UV aging.
Laboratory testing for 10 minutes versus 3 years of outdoor environmental testing. These are completely different levels.
Three conditions determine lifespan:
First, structure, not just adhesive. Adhesive ages. Truly reliable systems use: a one-piece die-cast shell + concealed sealing grooves + drainage slope design. A well-designed structure prevents water from entering.
Second, the breathing effect. Expansion occurs during the day due to high temperatures. Contraction occurs at night due to cooling. This creates negative pressure inside. Without a waterproof vent valve, moisture is drawn in, forming condensation. Many instances of "water ingress" are actually internal condensation corroding the circuitry.
Third, cable entry points. 80% of leaks occur here. There's no drip trap. No professional waterproof connectors.
No secondary locking mechanism. Water doesn't enter through the casing,
it enters along the lines.
IP65 is just the starting point. What truly determines lifespan is the engineering details. We'll see in three years.
