2: Different Types of Illumination
Channel letters are illuminated in a myriad of ways. Although you can choose channel letter signage that doesn’t light up in the evening, if you need visibility for 24 hours regardless of the prevailing weather situation, you should opt for illuminated channel letters.
Common types of illumination for channel letter signage include:
• Front Lit Channel Letters – These channel letters are made with an acrylic front face that is either clear or colored, plus aluminum backing and returns (sides).
• Reverse Lit Channel Letters – Sometimes known as “back lit” or “halo lit,” these channel letters have an aluminum front face and a back made of clear polycarbonate or acrylic. This allows light to shine through the back to create a glow between and around the letters.
• Open Face Channel Letters – This is another common type of channel letter with the face exposed to show neon tubing or bulbs inside. However, some light laws often forbid this type of channel letter in most regions.
You can also get specialty channel letter signs that blend various elements of these three types to give you the appearance and feel you desire.
