The WL-SLI-EXIIC is a robust, explosion-proof LED obstruction light engineered for low-intensity nighttime marking in environments classified as hazardous due to the presence of flammable gases, vapors, or combustible dust. Designed specifically for critical infrastructure such as power plants, petrochemical masts, chimneys, oil and gas derricks, flare stacks, and offshore installations, this beacon ensures visibility, safety, and long-lasting performance even in the harshest operating conditions.
Built with a die-cast aluminum alloy enclosure that is copper-free and powder-coated for added durability, the WL-SLI-EXIIC offers superior protection against corrosion, shocks, and environmental damage. It is certified explosion-proof with a protection degree of EExd IIC T6 and rated IP66, providing full resistance to water ingress and dust penetration. The unit is lightweight and easy to install, thanks to a self-contained wiring compartment that simplifies mounting and maintenance procedures.
This light features a red, steady-burning LED signal with a horizontal coverage of 360 degrees and a luminous intensity exceeding 32 candelas. Its efficient LED technology delivers an average lifespan of up to 100,000 hours while consuming only 8 watts of power, significantly reducing energy use and maintenance needs over time. It complies with several global photometric and safety standards, including ICAO Annex 14 (Type B low intensity), FAA AC 150/5345-43F (Type L-810 red), and ATEX certifications (BKI 06 ATEX 051 and INERIS 01 ATEX 0056X).
The WL-SLI-EXIIC can operate across multiple input voltage options—24VDC, 48VDC, and 110VAC—and is also available as a double-unit configuration for redundancy or enhanced visibility. It supports an optional integrated photoelectric switch with adjustable sensitivity from 20 to 3000 lux, enabling automated day/night operation. A stainless steel radiation shield further enhances protection and light distribution.
With a body constructed from corrosion-resistant aluminum and a glass cap that ensures optical clarity, the WL-SLI-EXIIC is ideal for continuous duty in extreme industrial settings. It functions reliably within a wide ambient temperature range of -20°C to +52°C, making it well-suited for both onshore and offshore hazardous zones requiring strict adherence to aviation safety standards.
