These are awesome lamps.  Chrome base with metal chrome shade.  I'm not sure of thr brand but is labeled luminaire on the bottom(pictures included).  Absolutely love these lamps but the only downfall is I do believe the cords have possibly been replaced or the cords were made shorter than normal.  Cord is around 15 to 17 inches long 28th turn switch.  They are adjustable at the neck of the lamp and very restoration hardware pottery barn style.   Very well made with a nice twinkle shimmer on the shade.  As you can see from the pics I have one in my bathroom turned on and it looks stunning.  Makes me want to keep myself but stuffs gotta go.  Thanks for viewing and please feel free to make me an offer.
