The Ayrton Series Marine-Grade variant is purpose-built for exposed coastal environments, making it ideal for ports, docks, and seaside infrastructure. With a C5-rated marine grade finish, IP66 protection, and 5000-hour salt spray test to comply with ASTM B117-2019/ISO 9227 standards, it offers proven durability in harsh maritime conditions.

Forward-throw optics enable low tilt angles and a compact profile, reducing wind load on masts - crucial in windy coastal areas. Available in high-mast and floodlight configurations, with custom optics and smart control options, it delivers reliable, efficient lighting for demanding coastal projects.

Polar: solid green C0–C180, dashed blue C90–C270, dotted amber the plane through the brightest direction when it lies between them; rings at 25% steps of the peak. Isolux: the footprint on the floor with the fitting aimed straight down, contours at 50%, 25% and 10% of the brightest point, grid in mounting heights (H). Both are drawn from the first measured file for that optic.

DESIGN FEATURES


Marine-grade lights designed for PURPOSE

The Ayrton Series Marine‑Grade variant has a range of features that ensure it is suitable for exposed coastal and windy environments, particularly where resistance to salt spray is critical: C5 corrosion-resistant finish (marine-grade powder coating): This upgrade offers superior protection in coastal zones frequently exposed to salt-laden air. The light with its durable coating (200 μm thick) has been tested to 5,000 hours of salt spray (ASTM B117/ISO 9227), ensuring long-term resistance to corrosion. IP66-rated, pressure-tested modular LED modules: Each LED module is individually pressure-tested and sealed to IP66 standards. The modular “chimney” layout improves thermal dissipation and reliability, even in humid, salty, or rain-prone coastal environments. Engineered for high-wind areas: Specialist forward-throw optics allow for installation at low tilt angles. Combining this with the compact, aerodynamic design minimises wind resistance and structural stress, making it ideal for tall masts and exposed coastal installations that frequently experience strong winds. Heavy-duty aluminium alloy housing: Constructed from aluminium alloy, the housing offers both mechanical strength and corrosion resistance - key for coastal locations prone to high winds and airborne salt. Integrated surge protection (TVS + optional SPD): Transient Voltage Suppressors (TVS) and optional Surge Protection Devices (SPD) rated up to 20 kV/10 kA protect against power surges and lightning strikes common in coastal storms. Precision optics with environmental control: With over 30 optical configurations (e.g., asymmetric, symmetric, back-spill guards), the light can be tailored to reduce glare, light pollution, and light spill - important in environmentally sensitive marine settings. McFarlane Series - Lower power marine-grade lights Kellwood's McFarlane Series can be configured to provide the same corrosion-resistant features, for applications requiring a lower output floodlight
