IP20 for indoor dry areas, IP65 for bathrooms and covered outdoor, IP67 for underwater and rain-exposed. Buying higher IP than you need wastes money. Buying lower than you need kills the strip.
What Each IP Rating Actually Means
IP stands for Ingress Protection. The first digit is dust protection, the second is water. Most people only care about the second digit for LED strips.
| Rating | Dust | Water | Where to Use |
|---|---|---|---|
| IP20 | Finger-safe | None | Indoor dry |
| IP65 | Dust-tight | Water jets | Bathrooms, covered outdoor |
| IP67 | Dust-tight | Temporary immersion | Outdoor, rain-exposed |
| IP68 | Dust-tight | Continuous immersion | Underwater, pools |
Common IP Rating Mistakes
Buying IP20 for a bathroom: the humidity will corrode the PCB in 6 months. Use IP65 at minimum.
Buying IP68 for covered outdoor: overkill, costs 30% more. IP65 is fine under a roof.
Forgetting that IP rating applies to the strip, not the connectors. You need IP-rated connectors too.
