L550-XXX-SE-G
Medium intensity obstruction light
Obstacle light for day and night time marking of structures that present a hazard to aviation. Optimized for use in Offshore environments. White flashing in day and White flashing or Red/Infrared flashing/steady in night mode. Incorporates the benefits of advanced LED, optical and system control technologies to meet the most demanding applications.
Key features
- Designed for optimal corrosion resistance in offshore environments due to usage of best-in-class aluminium with “Excellent Resistance to Corrosion” classification and offshore proven coating system
- Optimised housing design minimizing the risk of coating damage during handling and installation
- Stainless steel mounting feet eliminating galvanic corrosion between feet and structure
- No maintenance required over service life.
- Orga optical design produces highly accurate and uniform narrow light beam
- Integrated design with build-in photocell and monitoring – no additional power supply enclosure needed.
- Integrated GPS based flash synchronization between lights, UTC 0.0.0.
- Low power consumption
- 15 year field proven power supply technology
- Made in the Netherlands
