The Drum Lamp Shade is the most universal style of shade. The tall, round shape works well on most lamp bases and incorporates seemlessly into home decor. Made of tailored silk-type shantung fabric with an off-white softback lining (black shades have gold softback lining) to create a warm, soft glow. The Drum Lamp Shade is part of the Royal Designs, Inc. Timeless™ Basic Shade Collection. Royal Designs has been in the lamp shade 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.
