This lamp shade is all about clean lines and contrast. The six-sided Hexagon Lamp Shade is quite versatile, but works best with lamp bases that are slightly more round and bulbous. It also comes in a wide variety of fabrics and color options to help you create the right ambience for your space. The Hexagon Lamp Shade is part of the Royal Designs, Inc. Timeless Basic Shade Collection. Royal Designs has been in the lampshade business since 1993 with our multiple shade lines that exemplify handcrafted quality and value. Height is measured by slant height from top to bottom of the lampshades? front face. Measurements listed as (TOP x BOTTOM x HEIGHT). Please measure your existing shade--a replacement harp may be needed for a proper fit or additional adjustment if changing height of shade.
