IP ratings explained: IP20, IP44, IP65, IP66, IP67

Short answer

An IP (Ingress Protection) rating has two digits: the first is protection against solids and dust (0–6), the second against water (0–9). Use IP20 indoors, IP44 or higher in bathrooms and covered balconies, IP65 or higher for lights exposed to rain such as flood lights, gate lights and street lights, and IP66–IP67 where there are strong water jets or temporary flooding.

हिंदी में

IP रेटिंग का क्या मतलब है?

IP के पहले अंक से धूल से सुरक्षा और दूसरे अंक से पानी से सुरक्षा पता चलती है। घर के अंदर IP20, बाथरूम में IP44, और बारिश में खुली लाइटों के लिए कम से कम IP65 लें।

Questions people also ask

Is IP65 waterproof?
+
IP65 protects against water jets from any direction — fine for rain. It is not rated for immersion; that needs IP67 or IP68.
What IP rating for a bathroom light?
+
IP44 or higher, and higher still for fittings close to or inside the shower area.

General guidance only — follow IS 732 and your local electrical rules, and use a licensed electrician.
