Creo Industrial Arts developed an innovative design for Pottery Barn’s exterior letterforms that utilized LED light fixtures, and a removable cast translucent letter back allowing quick removal and replacement of LED. To achieve the desired lighting effect, the letter back was cast with integral color that transformed the cold blue LED light into a warm glow similar to incandescent bulbs. The result was a sign with letters that glowed warmly and evenly, and could be easily and cost-effectively serviced.
