Profile 3+6 combines both profile 3 and 6, i.e. LED channel letters are illuminated both from front and back. Profile 3+6 allows to illuminate the channel letters’ back and front in different tones. This allows using, for example, a dark blue shade, which may be too intense for the eye during darker times and reduce the readability of the sign or logo, but which would be more eye-friendly and less intense thanks to a white glow behind the letters.
