These LED channel letters for LSI Solutions have a silver face that works perfectly against this building exterior. We did an LED retrofit on these letters to get them looking brand new. Neon often encounters issues the longer it is in the elements, and LEDs are the modern solution. The LEDs offer energy saving benefits along with the brightness being much higher than that of which neon can output. The lighting effect on these letters is called halo lighting, as the letters are stood off the building by 2” using spacers that allow light to flow around the outside of the letters and give off a glow instead of the faces being lit.
