FAQ

Why is my illuminated sign not bright enough?

Usually because it was edge-lit rather than back-lit, or built with opaque white acrylic instead of opal. Both stop the face glowing evenly. It is a build fault, not the LEDs being too weak, and it can be corrected.

Why did half my sign suddenly go dark?

A sudden loss of one section is typically a failed LED run or a dead driver powering that zone. The rest of the sign keeps working because it is on a separate string. Both are repairs if the box can be opened.

Can a dim sign be fixed without replacing it?

Very often, yes. Failed LEDs and drivers are swapped out, and a wrong-acrylic or edge-lit face can be re-made as a back-lit opal panel inside the existing box. Full replacement is usually only needed when a box is water-damaged or sealed shut.
