Reversed Channel Letters (Halo-Lit)

Halo-lit letters with polycarbonate backs are illuminated signage commonly used in the industry. These letters are typically constructed with metal faces and returns, and polycarbonate (a durable, translucent plastic) backs. 

When illuminated from within, they create a soft, indirect glow that projects light through the polycarbonate backing, forming a striking halo effect around the letters. This combination of materials allows for eye-catching, energy-efficient signage, making them a popular choice for businesses seeking a modern and visually appealing signage solution.
