Led Sign Custom Illuminated 3d Acrylic Backlit Letters

Let’s talk about the visual effect. The goal is a clean, defined outline, not a blurry mess. To achieve this, the light source matters. We don't just stick LED tape inside the can. We use rigid LED modules mounted on aluminum circuit boards (PCBs). Why aluminum? Because LEDs hate heat. The aluminum pulls heat away from the chip much faster than standard fiberglass boards. This keeps the light output bright and prevents that ugly "blue shift" that happens when white LEDs get overheated and start failing. We typically set the color temperature to a 4000K Natural White or 3000K Warm White, which offers a much classier look than the harsh, blue-ish daylight colors you see on cheap storefronts.

Durability also comes down to the paint job. Since these letters are often mounted on high-end stone or wood facades, you cannot afford rust stains running down the wall. We construct the shell from heavy-gauge aluminum or stainless steel, but the secret is in the finish. We use a double-layer powder coating process, baking the paint at 200 degrees Celsius. This creates a hard shell that resists chipping and salt spray corrosion far better than standard spray paint.

Finally, we need to address the installation. Mounting these signs can be tricky because they need to "float" off the wall. We provide threaded stainless steel rods rather than simple screws. You can adjust the distance from the wall (usually 30mm to 50mm) to fine-tune exactly how wide you want the halo glow to be. If your building facade is uneven—like a rough brick wall—these adjustable rods are a lifesaver. We also include a paper installation pattern with every crate, so your contractor knows exactly where to drill without guessing. It is about making sure the sign looks as good on your building as it did in our factory.
