Product Overview
When standard front-lit signage isn't enough to capture your brand's prestige, our 3D LED Backlit Letters deliver the ultimate visual upgrade. Manufactured directly in our specialized architectural signage facility, these signs are designed to direct high-intensity LED light backward against the wall. This washes your building's facade in a soft, elegant glow while keeping your brand name sharply silhouetted in the front. Highly favored by luxury boutiques, modern law firms, upscale hotels, and corporate lobbies, this reverse-lit technology turns your business storefront into an unforgettable piece of architectural art.

Flawless Halo Diffusion: The secret to a premium backlit sign is the precise calculation of depth and LED density. Our engineers ensure the exact spacing between the internal LEDs and the acrylic diffuser to guarantee a smooth, continuous halo of light—eliminating any harsh "hot spots" or uneven shadows against your wall.
Commercial-Grade Weatherproofing: Engineered for true exterior longevity. We utilize strictly waterproof LED modules completely sealed within the metal housing. Your backlit sign will effortlessly withstand heavy rain, dust, and temperature fluctuations.
Safe 12V Operation & Energy Savings: Operating on a 12V DC low-voltage system, our 3D LED letters are incredibly safe to touch. The advanced LEDs significantly reduce commercial electricity consumption compared to traditional neon or incandescent lighting, making it an eco-friendly choice.
Secure Global Logistics: 3D signs require specialized handling. We meticulously wrap each letter in protective foam and pack your entire order in a reinforced wooden box, ensuring your custom signage arrives in pristine condition, ready for immediate installation.
What exactly is a backlit or "halo-lit" channel letter?
A backlit (or reverse-lit) channel letter features a solid, opaque front face—usually made of stainless steel—and a clear or frosted acrylic back. The LED lights inside are aimed backward. When mounted slightly away from the wall using standoff bolts, the light reflects off the wall surface, creating a beautiful glowing "halo" effect around the dark silhouette of the letter.
Are these backlit signs safe and durable for outdoor building facades?
Yes, absolutely. Our custom backlit letters are heavily engineered for exterior commercial use. The housings are constructed from rust-resistant stainless steel, and the internal lighting utilizes fully sealed, waterproof LED modules. They are built to endure harsh rain and sun while maintaining their 30,000-hour lifespan.
How do I install these letters to get the floating halo effect?
We provide everything needed for a perfect, professional installation. The back of each letter features threaded holes. You simply insert the included standoff bolts (back screws), push the electrical wires through the wall, and secure the letters. The standoffs automatically create the perfect gap between the letter and the wall to allow the light to escape and form the halo.
Do you provide the power supply for the LED letters?
Yes. All of our LED business signs operate on a safe 12V DC power system. We include the appropriate AC 110V-220V to DC 12V transformer (power adapter) tailored to the total wattage of your specific custom sign.
