Extreme light technology (XLT) is a break through 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 LEDs and increased versatility while maintaining low power consumption and vibration resistance expected from LED devices. 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. The 27XL is type 4X rated and constructed to IP66. Corrosion resistance is achieved with a powder coat finish applied over the copper-free aluminum housing. Federal Signal model 27XL is specifically designed for explosion proof atmospheres and/or corrosive environments. Because it is easy to install and requires very low maintenance, it is ideal for use in areas such as oil rigs, mines, refineries and chemical plants.
