Federal Signal model 371 incandescent warning lights have a powerful sealed beam lamp that rotates 360 within a glass or polycarbonate dome. Power is delivered to the Commander rotating lamp by a unique collector ring. The lamp itself is mounted in a pivoting yoke. This allows the lamp beam angle to be adjusted through 90 deg from horizontal to vertical. Changing the beam angle allows the user to create unique light patterns and/or direct the light for better visibility. The model 371 features a 200 watt sealed beam lamp and a high temperature resistant glass dome. The glass dome of the 371 is ideal for applications such as steel mills or arc furnaces/smelters where high ambient temperatures or red hot materials would melt or damage the polycarbonate dome. The 371 is available in Amber, blue and Red. The dome ring assemble simply screws on, providing easy access to the interior of the light. The new 371 base features electrostatically applied (e-coated) black epoxy paint for greater corrosion resistance. Wiring can be routed through the pipe mount opening in the bottom of the light or the two side knockouts can be used for side entry wiring. Installation can be surface or 1-inch NPT pipe mount. Optional wall and corner mount brackets are available.
