The PDL Sign Pro Tip: In our lab tests at The PDL Sign, we found that RGBW channel letters are ideal for storefronts needing vibrant color effects combined with clean white illumination during business hours—something Grandview does not natively support.


What are the different types of channel letter signs?

Channel letter signs are categorized into front-lit, backlit (halo-lit), front and backlit, and open-face designs. Each type offers distinct lighting effects and is selected based on the brand’s visibility and aesthetic needs.

Details: Channel Letter Types

  1. Front-Lit Channel Letters: LEDs illuminate through the letter face.
  2. Backlit (Halo-Lit) Letters: Light projects onto the wall behind for a halo effect.
  3. Front and Back-Lit Letters: Combines front illumination and rear halo lighting.
  4. Open-Face Letters: Exposed neon or LEDs for a retro look.

The PDL Sign Pro Tip: Our team recommends front and back-lit RGB letters for businesses requiring maximum visibility and dynamic effects.


What are the key differences between channel letter signs and box signs?

Channel letters are individual 3D letters, while box signs are enclosed structures with the graphic or text displayed on a flat surface. Channel letters offer a modern, dynamic appearance, whereas box signs are more traditional and less customizable.

Comparison: Channel Letters vs. Box Signs

FeatureChannel LettersBox Signs
StructureIndividual 3D lettersFlat, enclosed box
LightingRGB, halo, or dual lighting optionsInternal illumination only
CustomizationHighly customizableLimited customization
AestheticModern and sleekTraditional

The PDL Sign Pro Tip: We often see clients opt for channel letters for storefronts due to their vibrant, eye-catching appeal, while box signs are more common for industrial or wayfinding purposes.


What is the difference between channel letters and reverse channel letters?

Channel letters are front-lit, projecting light outward through the face, while reverse channel letters (halo-lit) project light backward onto the mounting surface, creating a glowing halo effect.

Details: Channel Letters vs. Reverse Channel Letters

FeatureChannel LettersReverse Channel Letters
Lighting DirectionOutward through the faceBackward onto the wall
Typical UseRetail stores, malls, restaurantsLuxury brands, professional offices
CustomizationRGB, RGBW, front/back-lit optionsHalo depth and color options

The PDL Sign Pro Tip: Reverse channel letters work best on light-colored or reflective walls to achieve a well-defined halo effect.


What is the difference between front-lit and backlit channel letters?

Front-lit channel letters illuminate through the letter face, while backlit channel letters create a halo effect by projecting light onto the wall behind. Front-lit designs offer higher visibility, while backlit designs provide a more sophisticated aesthetic.

Comparison: Front-Lit vs. Backlit Letters

The PDL Sign Pro Tip: Adding RGB functionality to backlit letters can create dynamic halo effects, perfect for premium branding.
