My grandparents had those huge bulb lights on a huge red tip bush in the front yard. They had grow into the bush I believe as they never came down for years... crazy thing was I was sure they were older than me and every bulb still worked. Im not sure how they didnt set the yard on fire knowing how my grandfather wired things up.A truly funny aspect of the aluminum tree is that it was considered the "safe alternative" to a real tree. Had anything come within a foot of those spotlights it would have burst into flames! However, it still was safer because of the string bulbs used to light real trees. You know the kind... the same ones people used on the outside of their houses. If you took them out of the socket and through them on the street or sidewalk they would make a very cool popping sound. I only know about this because I read about the "popping sound" in a magazine once. Yeah, I read about it, that's it...
The florescent light in his shop kept tripping the breaker. So he cut the ground off the cord and plugged it back in. If you used the switch on the wall it was fine, but touch thre pull cord on the light and 1,000,000VAC(whatever those fluorescent ballast transformers put out) would run thru your hand and out your foot... shoes did not make a difference.
