IP67 Strip Lighting
The IP67 rating officially stands for “temporary immersion to at least 1m from bottom and 15cm from top of object”. This means that the product is fully sealed against dust and can actually be fully emerged into water for a small period of time. If you are looking at running high power LED strips inside of these silicon sleeves, be prepared for them to quickly become dimmer or even die just after a few months of usage. Often these silicon sleeves are used for digitally addressable RGB strip which means an LED won’t be on at full power all the time and gets a chance to cool off which helps prevent that issue somewhat.
Like the IP65 rated strip they are great to use outdoors and can be used a bit less protected from the elements. Since this type of LED strip is fully sealed, you can’t mount it inside of an aluminium profile either. That can make mounting easier but also means this strip cools a lot worse then the IP20 and IP65 variants.
