On-Air RET-120IOA-BE is a Retro style 120 Volt incandescent ON AIR Light that comes with a blue vinyl lens. The instantly recognizable RETRO warning light is used throughout broadcasting facilities. The aluminum housing is formed by traditional sand-casting methods, machined, and then polished to a chrome-like finish. Illumination is provided by either a modern LED light strip or via incandescent bulb. The lens is cut from sign grade Lexan with a clear lens in front for vinyl protection and visual depth. The back plate is pre-drilled to mount to a single/dual gang electrical back box or VESA-75 mount.
