Uno Lamp Shades are used when restoring old floor lamps.....the original reading lamp. Known as bridge lamps, they are defined by a integral horizontal arm which the shade hangs from. This unique application requires special uno lamp shades, having a threaded ring fitter to screw directly onto threaded lamp socket. Once shade is attached, light is directed downward for task lighting. Whether restoring the complete lamp or just needing a update, replacing the uno lamp shade provides a fresh clean look. Choose stitched candlewick, natural mica, country linen, upscale silk or scenic parchment. Size is relatively consistent between uno lamp shades as the floor lamps, these shades are used on, are generally similar in size with like proportions.
