  • Federal Signal’s Model 27XL explosion proof LED warning light with XLT produces 60 high-intensity flashes per minute and is unique to the market because it covers an entire range of possible mounting configurations-including dome up. 

    This warning light operates on 24VDC, 120VAC, and 240VAC 50/60Hz and is UL Listed for Class I, Division 1, Groups C and D; Class II, Division 1, Groups E, F and G; Class I, Division 2, Groups A, B; and Class III. The 27XL is also Marine Rated.

    Extreme Light Technology (XLT) is a breakthrough, high-intensity LED array designed to meet the demands of industrial customers, producing maximum light output and superior lens fill. Configurable to either steady burning state or flashing mode, XLT provides improved performance over standard LED’s and increased versatility while maintaining low power consumption and vibration resistances expected from LED signals.

    The 27XL features a standard low in-rush circuitry design that provides greater compatibility with factory automation control systems and less electrical interference with in-rush sensitive devices.
