It is a spy pen. It's possible? I don't know how HEV interacts with stuff vs a UV light. My daughter has some https://puttyworld.com/collections/glow-in-the-darks-1/products/ion that glowed after exposing it to the light for a few seconds.
I always use probabilistic language when I did not directly observe the event myself. I have no reason to doubt his account, but for all I know an orb of ball lightning might have slipped into the wall when he wasn't looking :biggrin:
I'd remove the plate and have a look inside, but I'm still recovering from hip surgery at the moment and don't want to mess with electronics right now :wink:
No, I'm positive he wasn't poking at it. I was in the room when it happened. The switches were in the exact positions shown in the first photo. For the slider switches, you slide them up for increased intensity.
They're dimmers. It might look it in the photo, but the screw isn't lose. And yeah, that handle kept popping off and ended up getting lost at some point. It's just a plastic cap, the switch still works.
Here it is from a different angle.
Thank you for both these responses. The first for a potential explanation of the phenomenon, the second so I could reinforce to my wife NO WE ARE NOT GOING TO TRY AND MAKE IT HAPPEN AGAIN.
She is why we can't have nice things
Hi, so I was hoping to get an EE's explanation for what just happened. So my son was apparently over by the light switch pointing a UV pen light at the switch. Suddenly there was very loud, gunshot-like pop, sparks flew, and I had to go reset the breaker.
Maybe correlation doesn't imply...
