Insignia manufactured reverse halo lit channel letters with neon & LED lighting. We utilized our high reach lift truck to install the letters which are hung aproximately 28 feet high at the top of a two story commercial office building. The south facing letters are 1/2" thick aluminum flat cut non-illuminated letters. The interior unit id signs are made of acrylic and are ADA compliant (California Type II Braille). The unit ID's also have etched magnesium plates that contain the ADA braille.
