They consist of the front made from aluminum sheet 2 mm thick, sides from aluminum tape 1.0-1.5 mm thick and modules LED Samsung GOQ. A diffuser, which scatters light, is mounted on the back. Letters with so called Halo effect are mounted on distance bolts and then to the elevation or wall.
In letters with Halo effect the light is directed to the back of the letter, illuminating the space behind it and creating a glow.
They are a great alternative for classic frontlit letters. Available width of the tape ranges from 55 to 160 mm, which is adjusted to the size of the letter.
We give 5 years of warranty on those letters.
