Description

High-Intensity Visual Warning

The Federal Signal 151XST hazardous location strobe light provides a strong visual signal for demanding industrial environments. It flashes 80 times per minute, which helps draw attention during urgent events. In addition, the 151XST strobe light produces 520,000 peak candela and 165 effective candela. This output makes it a strong choice when facilities need a bright, recognizable visual warning. It can support plant evacuation, process communication, equipment status alerts and general safety notification.

Designed for Hazardous and Corrosive Locations

Federal Signal designed the 151XST strobe light for hazardous locations and corrosive industrial environments. It carries ratings for Class I, Division 2, Groups A, B, C and D. It also supports Class II, Division 1, Groups E, F and G, plus Class III locations. Therefore, it can fit many industrial applications where dust, vapour or other hazardous conditions may exist. The coated aluminum base adds corrosion resistance, while the glass lens supports durability in tough plant environments.

Protected Lens with Included Dome Guard

The 151XST includes a dome guard over the glass lens. This guard helps protect the strobe from accidental contact with moving equipment. For example, it can help reduce risk from forklifts, carts or maintenance activity near the warning light. This added protection supports longer service life and helps keep the light visible when facilities rely on it for communication. The strobe tube also offers a 10,000-hour lamp life, which helps reduce maintenance requirements.

Flexible Mounting Options

The Federal Signal 151XST hazardous location strobe light offers practical mounting flexibility. Teams can order the pipe-mount version for 3/4-inch NPT pipe mounting. Alternatively, they can choose the surface-mount version when the installation requires direct mounting. This flexibility helps match the light to existing plant layouts, panel packages, structural supports or equipment skids. Additionally, the available LHWB hazardous location mounting bracket can support select wall-mount applications.

Multiple Voltage and Lens Colour Choices

The 151XST strobe light supports common industrial power requirements. It is available in 12–24 Vdc, 120 Vac and 230–240 Vac models. As a result, teams can match the light to control systems, panels or plant power standards. The product also offers six lens colour options: amber, blue, clear, green, magenta and red. This colour range allows facilities to align visual signals with site standards, alert levels or operating practices.

Built for Indoor, Outdoor and Washdown Areas

The Federal Signal 151XST supports indoor and outdoor industrial use. Its Type 4X and IP66 enclosure ratings help protect against water, dust and corrosion. It is also IP69K compliant and marine rated. Therefore, the 151XST strobe light can support demanding environments where washdown, weather exposure or harsh operating conditions matter. This makes it a practical option for industrial plants, processing areas and outdoor equipment packages.
