What are LED backlit signs?
LED backlit signs, also called halo-lit signs, reverse-lit signs, or backlit channel letters, are custom 3D metal letters or logos lit by LED. Each sign is built from a 3D metal letter shell and an acrylic back-panel, and every separate piece has its own LED lighting and circuit. Light passes out from behind the sign and washes across the wall to form a soft halo, so the letters seem to float off the wall with a strong sense of depth.
A complete LED backlit sign is generally made up of the following parts:
- Metal letter shell: A hollow 3D metal shell (called a channel in the U.S.), fabricated from 304 stainless steel by default, marine-grade 316 stainless steel for coastal outdoor sites, and aluminum on large backlit signs to cut weight.
- LED light source: The sign is lit by LED. Depending on the project we use LED modules, strips, or PCB LEDs to suit your custom sign, running on a safe 12V DC supply by default, with a bright output and an LED rated for over 100,000 hours.
- Acrylic back-panel: The acrylic back-panel closes the shell and works as the light-transmitting layer, letting the LED light spread evenly from inside the shell so there are no visible LED hot spots, for a cleaner, more even look.
- Wiring and power: Each separate piece includes a quality UL Listed two-core wire that connects the 12V DC positive and negative. By default we use a quality Mean Well power supply to give the whole backlit sign stable power.
- Mounting: The sign mounts to the wall with stud bolts by default. If it needs to sit off the wall, we also provide spacers to hide the studs and wiring and to set the off-wall distance.
