I have to try a different bulb, however the one I used is a 3 way and was brand new in box. The switch does not change the brightness. Will report back. Quality is not great. Threads for attaching light to lamp base are not straight. There is also a bead on both sides where the glass was made from a mould. That wouldn't bother me if the bead didn't run directly opposite where the cord comes out of the base so either bead/ line in the front of lamp or cord visible from side. And no the base where the cord comes out does not move. Ok I guess I'm not a fan. Might return.
