Waterproof LED Strip Guide: IP65, IP67, and IP68 Explained
June 16, 2026
How waterproof LED strips are built, which IP rating to use outdoors, and what to verify on export orders for facades and wet areas.
Waterproof LED Strip Guide
Quick Answer: Waterproof LED strip is rated by IP code: IP65 resists water jets, IP67 handles temporary immersion, IP68 suits continuous submersion. Construction may use silicone sleeve, full extrusion, or potting — each affects flexibility, heat, and delivered lumens.
IP Rating Overview
Construction Methods
- IP65 — nano-coating or silicone sleeve on PCB - IP67 — full silicone extrusion around assembly - IP68 — potted resin with sealed end caps
Higher IP may reduce measured lumens 10–15% vs bare strip — specify per IP variant.
Field Rules
Every cut, connector, and feed must restore the same IP level. Weak joints cause most outdoor failures.
Q: Is IP65 enough for outdoor facade? A: Exposed architectural lines should default to IP67 minimum in most climates.
Q: Can waterproof strip be cut on site? A: Yes at marked points — re-seal with manufacturer-approved methods.
Conclusion
Specify IP at the system level, not only the reel SKU. Request test reports tied to your BOM revision for export acceptance.
