I have a lamp on which the metal shade is wide, but not long (as in vertically). It is rather attractively designed. However, when I screw on the lamp shade so that the top of the screw holding it is adequately covered by the peice on top, it doesn't go low enough to cover the lightbulb, which allows it to be too bright and annoying, not to mention ruining the look of the lamp. If I move the shade down, the piece on top isn't long enough to cover the screw that is above it. So I must either have an ugly lamp or one that is too bright. Man, that's annoying.
