Neon light exploding and falling from fixture

Posted by Lesley on August 12, 2007, 4:40 pm

What would cause a neon light to suddenly explode and fall from its fixture?
There was a buzzing sound before it happened. It was two 6 foot long neon
tubes that both basically exploded and came crashing down on the floor. I am
afraid to replace these tubes until I know this will not happen again.

Has anyone ever had a neon light fixture do this?

Neon fixtures use very high voltage. A short circuit in the fixture could
cause this. What is this being used for?

As Noozer pointed out, I meant to say fluorescent. The fluorescent lights
are used in the carport. They are under cover and I could not see any water
or anything getting in there. They are exposed to hot and cold temperatures,
mind you, because there is no door on the carport.

Were you there and observed them when they exploded?

If not, is there a possibility that somebody or something came into the
carport and bumped into them?

I've never seen or heard of that happening. If these lamps are in fact
fluorescent, and six feet in length, that in itself is an uncommon fixture.
Common lengths for fluorescent fixtures are four feet and eight feet. A six
foot fixture could be a hybrid and need special lamps
