Waterproof COB LED Strip: IP20, IP65, IP67 and IP68 Guide

COB LED strips can be supplied in indoor and waterproof versions, but the correct IP rating depends on the installation environment. IP20 is for dry indoor use, while IP65, IP66, IP67 or IP68 options may be needed for damp or outdoor conditions.

For outdoor projects, the IP rating is only one part of reliability. Cable exits, end caps, connector sealing, mounting direction and installer cutting method also matter.

IP ratings describe protection against dust and moisture. For COB strips, waterproof coating or extrusion can change cost, thickness, heat behavior, connector method and lead time.

The same COB model may be quoted differently when supplied as IP20, IP65 or IP67, so buyers should request each version separately when comparing costs.

IP20 COB strip is suitable for dry indoor profiles, shelves, cabinets and furniture details where moisture exposure is low. It is usually easier to cut, connect and install than waterproof versions.

For many aluminum-profile installations, IP20 can be the most practical choice if the profile and diffuser provide enough physical protection.

IP65 and IP66 options can suit damp or protected outdoor areas, depending on the sealing method and installation direction. IP67 or IP68 versions provide stronger moisture protection but still need correct cable and end treatment.

Do not assume a high IP rating means the strip can be cut and reconnected freely on site. Field cutting can create risk if the sealing method is not controlled.

Outdoor COB projects should define sunlight exposure, rain direction, drainage, mounting surface, cable route, power supply location and maintenance access.

For larger projects, factory-cut lengths and prepared cable exits may reduce after-sales risk compared with field cutting and sealing.

Waterproof grade affects material cost, labor, accessories, packing and lead time. A buyer asking for the highest IP grade everywhere may increase cost and installation difficulty unnecessarily.

Separate the project by zones: dry indoor shelves, damp counters, protected outdoor lines and exposed outdoor runs may need different IP choices.
