What's the difference between IP67 and IP68?

What's the difference between IP67 and IP68?

When we buy the waterproof led strip, IP67, and IP68 hard to know, and hard to choose the best one for using?

For of all, IP67 waterproof means the led strip can be immersed in water 1-meter deep place for about 30 minutes, and IP68 waterproof led strip can be immersed in water 1-meter or more deep place for more than 30 minutes.

In this mean, IP68 would be more waterproof than IP67. If you use the led strip inside the pool, IP68 led strip is your best choice. If you use it just outside the door, IP67 is OK, no matter it's rainy or foggy.
