Starlight Backlit Channel Letter Sign | Perforated LED Letters

The shimmering “twinkle” effect is entirely optical and achieved through precision engineering. We use CNC lasers to pierce thousands of micro-holes through the solid metal face sheets. High-intensity LED modules are spaced precisely inside the hollow channel letter cavity. As a viewer walks or drives past the sign, their changing line of sight crosses the varying angles of the internal light rays passing through the micro-perforations. This creates a natural, mesmerizing “sparkle” or “starry night” illusion that captures attention far better than static flat signs.

No. While the metal face has micro-perforations that allow water to enter during heavy rainfall, the sign is engineered from the ground up for full external weather exposure. We exclusively use commercial-grade Samsung or Osram LED modules that are completely encased in solid IP67 waterproof resin blocks. All internal wiring connections are sealed using marine-grade heat-shrink tubing. Furthermore, precision drain holes are engineered into the bottom rear returns of the letters, allowing any water to drain clear through immediately without pooling.

These letters are designed with an open or clear acrylic rear casing paired with a perforated metal face. When the internal LEDs light up, the light splits into two paths. Part of the light shoots forward through the micro-holes to form the bright, crisp “starry face” profile. The remaining light floods out the back of the letter housing, casting a soft, wide halo wash onto the structural mounting wall. This dual effect prevents the sign from looking flat, giving it incredible 3D depth and improving legibility at night.

No, we prevent facade staining by utilizing premium, non-corrosive metals. Our starlight signs are built using high-grade 304 or marine-grade 316 stainless steel, or architectural-grade aluminium. After laser cutting the perforation patterns, the metal undergoes specialized chemical cleaning and edge passivation to seal the freshly cut interior walls of the micro-holes. This ensures that even in harsh, salty coastal areas, the holes will not rust, oxidize, or drip dirty water down your clean storefront walls.

To deliver an accurate, guaranteed commercial proposal within 12 working hours, please prepare the following details:

1. A complete vector artwork design file (.AI, .EPS, or editable .PDF format) with your desired overall dimensions and letter height specified.
2. The installation context: whether the sign is meant for indoor use or an exposed outdoor facade.
3. Your preferred material finish (e.g., Brushed Gold, Mirror Silver, or a specific Pantone powder-coated paint color).
4. The structural wall properties (e.g., masonry concrete, timber panelling, or glass) along with your location details to ensure electrical compliance and proper mounting hardware matching.
