Federal Signal's Model 121X rotating light flashes 90 times per minute and produces a 360 degree visual signal. This explosion-proof light has an incandescent lamp and is available in five lens colors: Amber, Blue, Clear, Green and Red. Model 121X is unique to the market because it covers an entire range of possible mounting configurations-including dome up.

The Model 121X is UL Listed for Class I, Division 1 and 2, Groups C & D; Class II, Division 1, Groups E, F & G; and Class III. The 121X is UL and cUL listed, Marine Rated and constructed to Type 4X, IP66 standards.

This corrosion resistant unit's copper-free aluminum housing is finished with a powder coat. 

The 121X uses a synchronous motor to drive a parabolic reflector around an incandescent lamp. This results in a 360 degree rotating beam which is concentrated in a horizontal plane.

The 121X features a spring clip-mounted lens for quick access when inspecting or relamping. The 121X can be paired with a pendant, ceiling or wall mount. Installation is simple; with the mounting box in place, the fixture is threaded onto the mounting box, making the electrical connection. 

Federal Signal's rugged 121X Warning Light is designed for explosion-proof applications and/or corrosive environments. It is ideal for use in indoor and outdoor areas such as oil rigs, mines, refineries, and chemical plants.
