Usually because they are attached to a light fitting. If you unscrew them from the fitting (bare fingers are best for this), they should attempt to rise.

In this case, the light fittings are at the end of short runs of cable and also get hot to the touch of bare fingers (ouch!), so some effect - at least a bend in the cable - should surely occur. :think:
