IP Rating for Outdoor Lights: Professional Guide

IP (Ingress Protection) rating per IEC 60529 classifies protection against solids and liquids. Critical for outdoor LED reliability.

IP Rating Structure

First Digit (0-6): Solid Protection

• 5 = Dust protected
• 6 = Dust tight (complete)

Second Digit (0-9): Liquid Protection

• 5 = Low-pressure water jets (12.5L/min)
• 6 = High-pressure jets (100L/min)
• 7 = Temporary immersion (1m/30min)
• 8 = Continuous immersion (1-3m)

IP65 Rating

Protection: Dust-tight + Water jets from any direction

Test: 12.5L/min, 6.3mm nozzle, 3 minutes

Applications: Covered outdoor, balconies, under eaves, protected walls

Limitations: Not for direct prolonged rain or immersion

IP67 Rating

Protection: Dust-tight + Temporary immersion (1 meter, 30 minutes)

Test: Submerge at 1m depth for 30 minutes

Applications: Outdoor yards, ground lights, rain exposure, poolside (non-submerged)

Handles: Heavy rain, temporary flooding, accidental submersion

IP68 Rating

Protection: Dust-tight + Continuous immersion (depth per manufacturer)

Test: Continuous submersion at specified depth (typically 1-3m)

Applications: Underwater lights, swimming pools, fountains, marine environments

Capabilities: Permanent underwater operation

Comparison Table

Selection Guide

• Indoor: IP44-IP54 sufficient
• Outdoor rain: IP65 minimum, IP67 recommended
• Ground level: IP67 (flood risk)
• Pools/fountains: IP68 mandatory
• Coastal/marine: IP68 + corrosion resistance

Hanwo products use IP67/IP68 with rigorous testing for reliable outdoor performance.
