I have the floor lamp model. Had it long time now. It has the piggly wiggly mercury bulb in it. Sticker inside shade says replace only with 120V PL and has diagram of the same piggle wiggly bulb. Have been wanting this mercury bulb to burn out, so I could take the lamp to Batteries Plus and see if I could get a daylight LED replacement. Do not buy and do not want those mercury bulbs in this house!
