AlthoughLED module are available in the full range of primary colors, like red,
white, blue, green...some LED colors perform better than others for channel letter
usage. Red, which is the oldest & most popular LED we have seen, one of the
brightest and also the least expensive, is obviously the most popular color used in
channel letters. Other LED colors aren't always as bright as red. Thus other LED color
selections are judged on a case by case basis of the sign size and how well the LEDs
can illuminate it. For other colors, signs guys usually have two choice, if they use
color tinted acrylic face, whey will choose LED module to be the same color as the
face, but white LED will be a better choice in case of they use white acrylic face and
translucent vinyl face. more information is in: www.ledmodulelight.com
