Illuminated LED Channel Letter
Channel letters are a type of electrical signage. The fundamental difference between channel letters and other signage types is that channel letters are dimensional. Each letter is individually formed, and has its own separate enclosure.Channel letters get their name from the internal “channel” contained by each letter. The internal channel is also where the letter illumination is housed. The side of a formed channel letter is called the “return”, and the return forms the letter enclosure (channel.)
