Side-Lit Channel Letters

Side-lit channel letters incorporate translucent acrylic returns, allowing light to shine through the sides of each character. The face can be opaque, illuminated, or crafted from a contrasting metal or acrylic. The illuminated returns add depth and enhance visibility from various viewing

angles. Businesses can select different colors for the face, returns, and LEDs to achieve custom branding effects, such as an opaque metal face with blue-illuminated sides or a white-illuminated face with red returns. Proper internal diffusion is essential to ensure even brightness and prevent visible LED modules. Side-lit letters are an excellent choice for retail stores, restaurants, entertainment venues, and modern architectural signs.

Side-Lit Channel Letters FAQ

How is side-lit different from edge-lit channel letters?

Side-lit letters use translucent acrylic returns so light shines through the sides of the letter body. Edge-lit letters instead illuminate through a thick acrylic face, with light refracting along the outer edges — a different construction for a different effect.

Can side-lit channel letters combine multiple colors?

Yes. Businesses can select different colors for the face, returns, and LEDs independently — for example, an opaque metal face with blue-illuminated sides, or a white-illuminated face with red returns.
