Knowledge Guide | IP66 vs. IP67? Understanding Dimming Power Supply Protection Through IP Ratings

IP66 or IP67? When choosing the protection rating for dimming power supplies, many are intrigued yet confused by these seemingly similar codes. Though differing by just one digit, they represent significant gaps in dustproof and waterproof capabilities.

1. IP Rating Basics

The IP (Ingress Protection) rating consists of two digits:

First digit (0–6): Dust resistance. Higher numbers mean better protection.

Second digit (0–8): Water resistance. Higher numbers indicate stronger waterproofing.

2. IP66 Explained

Dustproof (6): Completely dust-tight.

Waterproof (6): Withstands high-pressure water jets (12.5mm nozzle) from any direction.

Ideal for: Outdoor environments exposed to heavy rain, car washes, or splashing water.

Limitation: Not suitable for prolonged submersion.

3. IP67 Explained

Dustproof (6): Fully dustproof.

Waterproof (7): Survives temporary immersion (1–1.2m depth for 30 minutes).

Ideal for: Poolside lighting, outdoor gear, or scenarios requiring short-term water exposure.

How to Choose the Right IP Rating?

Assess Your Environment

IP66: Choose for outdoor areas with rain/splash risks (e.g., garden lighting, building facades).

IP67: Opt for locations needing temporary submersion resistance (e.g., fountains, marine equipment).
