My housemate left an amazon package that had a lamp in it (with a battery compartment - there's a hazard battery picture on the front of the box) on top of a radiator (wooden cover thing) that was going full blast for the best part of 12 hours (it's v cold here and heating was prob set to about 25 degrees)
Is it safe to use? The lamp was warm when I took it out of the packaging. I can't tell from a google so thought I'd ask.
