Illuminated acrylic channel letters and aluminum returns are manufactured for big size signage. For letter higher than 80 cm but less than 2 meters, it is compulsory for the returns to be aluminum, as it is more resistant to weather conditions. Usually, they are installed on building roofs or on hard-to-reach places with strong wind.
This system is highly durable and more affordable than the aluminum / flexible substrate system. Aluminum do not rust and time doesn’t change it. The only drawback is that sharp angles and irregular shapes can not be made.
Led illumination with high light yield is on more and more affordable prices, and almost fully replace the fluorescent lamps. More than 7 years, we use leds from one of the leading companies on the market, the Koreans G.O.Q. LED™. They are known with their very good characteristics and high resistance. For more complex project or on client’s request, we offer leds from the world-wide leader – the American company SloanLED™.
The illumination of the channel letters determines their warranty. Letters with Koreans leds are covered by 4-year warranty and 5-year warranty is given for the American leds. In both cases, the life cycle of the channel letters is at least 8-10 years.
