Channel letters are a specific type of electric sign. Individual illuminated letters or logos can be produced in virtually any size, shape, typeface or configuration. These letters are typically made out of aluminum or stainless steel with a translucent acrylic face allowing the light to pass through the front. Another option for channel letters is reverse lighting. This type of lettering is often referred to as ‘face’ lit or ‘halo’ lit. The letters are mounted away from the wall to allow for the ‘halo’ effect which is then projected back. Channel letters are popular for retail and brand identification projects.
