Backlit signs, also be called as halo lit signs or reverse channel signage, only the back-panel is illuminated, mostly using LED as light source. Individual fabricated metal signage shell with amazing halo effect.
Backlit signs have many indoor and outdoor applications, you always can find the LED backlit signage on storefronts or reception areas in all walks of life. In office, lobby, hotels, retail stores, buildings, churches and much more, these perfect halo effect signs make your signage always be the focus.
BTW, in some person mind, the backlit signs mean the signage surface is illuminated, because the signage factory use the neon or light bulbs as the light source before. They will place the lighting source on the back-panel then place graphics before it. But with the invention of LEDs, this idea became obsolete. We generally distinguish the signage option by the illuminated position rather than the light source position now.
