Sescom FSL-1 Three-Sided On-Air Lighted Sign (Non-Flashing)

The FSL-1 Three-Sided On-Air Lighted Sign from Sescom says ON-AIR on the front as well as the left- and right-side. It's a non-flashing alert sign with vertical red lettering on a white background. Use the included red bulb to make the sign glow red when the studio is "On the Air". The sign can be ceiling- or wall-mounted, and it can be used indoors or outdoors with the included gasket. The 120V, 75W incandescent fixture is wired for 120 VAC and recommended to be permanently hardwired to a 110V junction box.
