IP (Ingress Protection) rating is an international standard (IEC 60529) that classifies the degree of protection provided by electrical enclosures against intrusion of solid objects and liquids.
IP Rating Format: IPXX
First Digit (0-6): Protection against solid objects (dust, tools, fingers)
Second Digit (0-9): Protection against liquids (water, moisture)
Common IP Ratings for Industrial Lighting

How to Choose the Right IP Rating
1. Indoor Industrial Areas
General manufacturing: IP54 minimum
Dusty environments: IP65 recommended
Food processing: IP65/IP66 with smooth surfaces
Clean rooms: IP54/IP65 depending on cleaning requirements
2. Outdoor Industrial Areas
General outdoor: IP65 minimum
Coastal areas: IP66/IP67 (salt spray protection)
High rainfall areas: IP66 for heavy rain protection
Freezing conditions: IP65/IP66 with temperature rating
3. Special Applications
Washdown areas: IP66/IP67 (food, pharmaceutical)
Chemical plants: IP66 with chemical resistance
Mining operations: IP67 with impact protection
Marine applications: IP68 for submersion
