Question about Fatboy Edison the Petit

The lamp is waterproof, at least from above (rain). On the bottom, however, there are three cross screws that can be opened. The warranty may expire if you open the lamp yourself. My Fatboy also had a malfunction once, but I was able to have it replaced under warranty without any problems. Here is a picture of the underside: https://cdn.lamptwist.com/12104-thic...
