S.T. Dupont Défi Extrême Lighter – Fluo Neon Blue Product Description
Extreme High-Altitude Performance Meets High-Energy Neon Aesthetics
Designed to bring fresh energy to luxury classics, the S.T. Dupont Défi Extrême Lighter in Fluo Neon Blue (REF 021416) is inspired by cutting-edge fashion and high-performance automotive design. Part of the vibrant Fluo collection, this model pairs an ultra-durable matte black chassis with an electric, fluorescent blue trigger pop—crafted for lives always on the move.
Combining S.T. Dupont’s legendary lacquer artistry with all-terrain engineering, the Défi Extrême delivers extreme lighting capability, intuitive ergonomics, and bold contemporary style under all circumstances.
What Makes the S.T. Dupont Défi Extrême Fluo Neon Blue Different?
Unlike standard jet lighters that struggle under harsh weather conditions, the Défi Extrême series is specifically engineered for high performance in radical environments. Capable of functioning flawlessly at altitudes over 3,500 meters (11,500+ feet) and in extreme temperature ranges from -10°C up to +45°C, it is virtually indestructible.
The Fluo edition brings a popping, dynamic contrast to S.T. Dupont's most rugged chassis, delivering modern sports-car aesthetics paired with all-weather torch flame reliability.
Dynamic Fluo Neon Blue Accent
Features an electric fluorescent blue ignition trigger set against a sleek matte black protective armor, inspired by high-speed automotive and sportswear design trends.
All-Terrain Environmental Performance
Engineered to operate reliably in sub-zero freezing cold (-10°C), intense scorching heat (+45°C), and high-altitude mountain elevations exceeding 3,500 m.
High-Protection Armor Construction
Combines an injection-molded metal core with a highly resistant semi-rigid protective cover, safeguarding internal mechanisms against impacts, drops, and scratches.

Generates a powerful, rigid blue jet flame capable of resisting extreme winds and lighting cigars cleanly in a single pass.
