The Wolf LinkEx™ LFX Series LED Linear Luminaires (encompassing models LFX1S-12-55, LFX1S-12-65, LFX1S-16-45, LFX1S-16-55, LFX2S-24-50, LFX2S-24-60, LFX2S-32-50, and LFX2S-32-55) represent advanced solid-state linear lighting fixtures designed as direct, high-efficiency replacements for traditional enclosed hazardous area fluorescent fittings. Engineered and manufactured by Wolf Safety Lamp Company (United Kingdom)—the world’s leading authority in hazardous location safety illumination—the LFX Series holds full international explosion-proof certifications under ATEX and IECEx for Zone 1 and Zone 2 (Gas atmospheres) as well as Zone 21 and Zone 22 (Combustible Dust environments), delivering uncompromising worker safety in atmospheres laden with hydrocarbon vapors, industrial solvents, and combustible dusts.

Architectural breakdown by LED array configuration and thermal endurance:
- LFX1S Series (Single LED Array / Narrow Footprint): Serves as the direct replacement for standard 1-lamp fluorescent fittings (1x18W / 1x36W). Includes 12-LED (LFX1S-12) and 16-LED (LFX1S-16) variants.
- LFX2S Series (Double LED Array / Wide Footprint): Delivers double the luminous output for wider area coverage, replacing 2-lamp fluorescent fittings (2x18W / 2x36W). Includes 24-LED (LFX2S-24) and 32-LED (LFX2S-32) variants.
- Thermal Suffix Designations (-45, -50, -55, -60, -65): Indicate the maximum rated continuous operating ambient temperature (°C) for each specific model variant (e.g., LFX1S-12-65 operates reliably up to +65°C ambient, LFX2S-24-60 up to +60°C ambient).

Mechanically, the Wolf LinkEx™ LFX Series features an ultra-rugged enclosure molded from high-impact anti-static engineering polymer paired with an anti-static polycarbonate lens matrix that resists severe impact energy and corrosive chemical degradation. Its high-efficiency solid-state LED chips deliver >100,000 hours of service life, providing uniform, glare-free, natural white light at a fraction of traditional power consumption. Rated to IP66/IP67 ingress protection standards, the luminaires are dust-tight and high-pressure water-jet resistant. Featuring daisy-chain linkable interconnection capabilities and flexible voltage ratings (HV / LV), the Wolf LFX Series stands as an essential lighting infrastructure solution for offshore platforms, petrochemical refineries, chemical storage, shipyards, and heavy industrial maintenance overhauls worldwide.
