IP65 Strip Lighting
The IP65 rating officially stands for “Total dust ingress protection low pressure water jets from any direction”. The 6 stands for good dust and touch protection. Basically the LEDs cannot be reached so they are well protected. The 5 of IP65 stands for decent moisture or water protection. They should even survive a garden hose or something like that.
This makes these strips ideal to use in outdoor situations where they are still inside of an aluminium profile or something of the sort. The way they achieve this protection is by adding a resin or epoxy layer on top of the LEDs basically fully sealing off the top end of the LED strip including all the solder joints and contact points. That means that, when properly mounted, they can without moisture and won’t corride.
