Our LED by garageCube are not IP65 but IP60.
Which means the bars are carefully protected from dust but not from water.
You can use them outdoor, but the LED bars need to be safe, protected and covered.
Solutions exist : you can add silicon to all the LED's parts where the water can seep in.
However your LED bars will then be modified so they won't be under warranty anymore.
Feel free to contact the support team at anytime for more information.
