The first "official" night out in the properly mounted box was a bit of a surprise, and tested the box integrity.
I had not yet put silicon sealant around the dome, just some electrical tape as a placeholder - I didn't check the weather forecast!!! some water got in, but luckily nothing was affected - the electronics managed to stay dry.
Suffice it to say, there is a lot of silicon around it now, even though I will 100% be dismantling it in the next few weeks for a rebuild.
Major thunderstorm came over with some pretty impressive lightning around 1am and 3am.

It's only a 1:30 video, but the interesting bit starts around the 35 second mark.
