371ST Commander® Strobe Warning Light

- Three dome colors
- Surface mount and integrated 1-inch pipe mount
- Type 4X, IP66 enclosure

Federal Signal Model 371ST is a single-flash strobe housed in a NEMA 4X enclosure. At 60 flashes per minute and 275 effective candela, the Commander® is the largest strobe signal in the Federal Signal product line.
The 371ST features a heat resistant glass dome available in three colors (amber, blue and red). The dome and ring assembly simply screws on, allowing for easy access to the strobe tube and printed circuit board assembly.
The new base of the Commander features electrostatically applied, black epoxy paint for greater corrosion resistance. Wiring can be routed through the pipe mount opening in the bottom of the light or the side knockouts can be used for side entry wiring. Installation can be surface- or 1-inch pipe mount. Optional wall and corner mount brackets are available for the 371ST. The Commander is rated NEMA 4X, IP66 (watertight, dust tight, corrosion resistant).
The LWMB2 wall mount bracket and the LCMB2 corner mount bracket can be used to mount this strobe light.
