Fully lit letters or side-lit letters – why not both?
The translucent acrylic diffuses the LED light so that the letters appear fully lit – without any dark edges, as is sometimes the case with 3D letters assembled from multiple parts (front and sides). Coloured foils applied to the backside of the letters allow for a wide range of colours.
It’s also possible to add an opaque material, such as dibond or non-translucent acrylic, to the face of the letters so that they only glow on the sides. This gives the logo or design a floating quality that is very appealing. Or you can mix and match, having one part of your logo glow on the sides and another fully illuminated.
