The problem here is how stupid hot they get , I once ran a 90watt SOX tube outside on a concrete flag, I ran it for about 2 hours, then dumped it into a bucket of cold water just to see what would happen?
The resulting explosion set off next doors car alarm, a blew shards of red hot glass into my leg!
I really wouldn’t advise running it out of its jacket to be honest?,
Speaking from experience!
