Illuminated Otions of Channel Letters

There are a number of things to keep in mind when designing your channel letter sign. One of the most important factors to consider when it comes to channel letter signs is the type of lighting or illumination you want for your sign. 3 primary styles for channel letter signs:

Front-Lit or Standard Lit Channel Letter Signs

Front-lit channel letter signs are the most common and are the standard style used.

The construction includes aluminum side returns, aluminum/stainless steel backing, and an acrylic facing. The acrylic face can be translucent, white, or colored. LED lights are installed to the back panel and shine light through the front-facing acrylic material.

A unique feature of front-lit channel letter signs is that a digitally printed vinyl can be installed on the acrylic facing for a unique color effect.

Reverse-Lit or Reverse Channel Letter Signs

Reverse-lit channel letter signs allow light to escape from the back of the sign to produce a glowing effect around the edge.

The face of the reverse-lit channel sign must be composed of opaque aluminum so that the light inside doesn’t escape. Opposite of the standard, the backing of the sign will use clear acrylic material which allows the LED light to escape, this, in turn, produces that halo effect around the letter shape.

The lights are mounted on the back and point towards the face. However, since the face is aluminum, the light bounces off and out the clear, acrylic backing. It is necessary for reverse-lit channel letters to stand off the wall at least 1” to allow light to escape in an even pattern.

Note: Since there is more aluminum used and more welding, the cost can be slightly higher.

Open Face Channel Letter Signs or Neon Signs

This classic style is iconic. The revolution of the neon sign began with the Geissler tube in 1898. Scientists discovered that a sealed glass tube with the newly discovered neon gas emitted a lovely, bright luminous light when charged with electricity.

Open face channel letter signs play on this style. Using a clear acrylic facing, these signs provide the appearance of an open face so that onlookers can see the light within the letters. Traditional open-faced signs used neon, however LED’s are now commonly used.

Traditional open face neon uses a carefully bent glass tube that is filled with neon. There are three types of glass- clear, coated, and painted. While called “neon signs” thanks to that initial discovery of the glowing gas, to produce other colors it is necessary to use other types of gases.
