Okay, just got my first lamp, a Mathmos Jet (violet / blue) very very cool. It gets pretty hot though (guess that isn't much of a surprise) but wanted to know how long I should be running it at a go. Can it go overnight? Are they fire hazards? Does running it for too long at a go cause it to get damaged or the wax to fade? Since I bought it off of eBay there is no instruction manual where I could probably answer these questions for myself.
Thanks in advance.
