Channel Letters are individually illuminated letters and graphics. These signs are found everywhere. From shopping malls, to exterior storefront identification, these signs are the best way to see your business name in lights. Reverse channel letters are ones that have metal faces and sides, but have a clear plastic backing. These are designed to be mounted an inch or two away from the wall. At night, these signs create a halo-lit effect. Another type is one with 'open' faces. Though not actually open, the faces of these are clear plastic with the balance built just like standard channel letters. This allows for the raw neon to be seen, as well as the inside of the U-form itself. Open face channel letters are very effective for aggressively grabbing attention.
