Why IP rating matters
The IP rating describes protection against dust and moisture. For LED strip lights, it affects where the strip can be installed, how it should be mounted and how heat is managed.
Choosing the wrong IP rating can cause early failure, poor appearance or installation problems, especially in humid, outdoor or high-contact areas.
IP20 for dry indoor spaces
IP20 is typically used in dry indoor locations such as cabinets, shelves, aluminum profiles, furniture lighting and controlled commercial interiors.
It is easier to handle, usually has better heat dissipation than heavily coated versions and can be a cost-effective choice when moisture protection is not required.
IP65 for splash and damp protection
IP65 versions are commonly selected for damp locations, indirect outdoor details and areas where dust or occasional splashes may be present.
Buyers should confirm the coating or extrusion method, connector treatment and whether the installation environment includes long-term water exposure.
IP67 for stronger outdoor protection
IP67 is used when stronger moisture protection is required, such as exterior decorative lines, landscape lighting or facade details. It still needs correct installation and should not automatically be treated as suitable for permanent underwater use.
For outdoor projects, confirm cable exit, end cap, mounting profile, bending limit and warranty conditions before bulk order.
FAQ
Can IP65 LED strip be used outdoors?
It can be used in some protected outdoor or damp conditions, but the exact environment and connector treatment must be confirmed.
Is IP67 suitable for underwater use?
Not automatically. Long-term immersion requires a specific product design and installation confirmation.
Which IP rating is best for aluminum profiles?
IP20 is common for dry indoor profiles; damp or exterior profiles may require IP65 or IP67.
