I had a Son bulb Edison screw which had come out of a lamp after converting to metal halide, my wife wanted a bulb and found it in garage so fitted it to a up lighter, there was a rather loud bang as the fuse ruptured.

As said likely it is a tungsten from Ikea, but I would want to inspect the fitting to be sure.
