Heavy-duty, IP67 waterproof solar floodlights engineered for high mast towers, sports arenas, industrial complexes, and Qatar transportation infrastructure.
As the State of Qatar advances toward the sustainability targets codified under Qatar National Vision 2030, major infrastructural developments across Doha require robust, off-grid outdoor lighting solutions capable of continuous operation without grid dependency. Solar powered high mast lights—ranging from 15-meter to 35-meter mast configurations—serve as critical infrastructure elements for port logistics, expressway interchanges, stadium perimeters, and industrial mega-projects. However, deploying high-power solar LED luminaires in Doha presents an extraordinary set of environmental engineering challenges that standard commercial outdoor lights fail to withstand.
Doha experiences extreme summer ambient temperatures exceeding 50°C, with direct sunlight causing internal fixture temperatures to peak above 85°C. Traditional Lithium-ion (NMC) batteries degrade rapidly under such conditions, suffering thermal runaway risks and severe capacity loss within 1.5 years. Our high mast solar systems utilize EV-grade Lithium Iron Phosphate (LiFePO4) battery packs embedded with thermal insulation barrier layers and phase-change materials (PCM). Furthermore, the die-cast A380 aluminum alloy housing features patented heat dissipation fins designed via Computational Fluid Dynamics (CFD) modeling to induce natural convection cooling across the LED optical engine and driver enclosure.
Meeting Qatar Construction Specifications (QCS) and Ashghal (Public Works Authority) guidelines demands precise optical control to reduce glare and skyglow while maximizing uniformity (U0 > 0.40) over large surface areas. Our solar high mast luminaires utilize optical-grade PMMA lenses delivering Type II-M, Type III-M, and Asymmetric Flood light distributions. Designed for mounting heights from 12m to 30m, these units generate over 160,000 lumens per cluster while maintaining structural resistance to severe Shamal sandstorms with wind load ratings certified up to 160 km/h (45 m/s).
Continuous 24/7 off-grid illumination for container yards and deep-water terminal perimeters. C5-M marine anti-corrosion coating protects against high-salinity Arabian Gulf salt spray.
Zero-trenching, high-mast illumination for multi-lane interchanges and rest areas. Completely independent of grid fluctuations during peak summer electricity demand.
ATEX compliant options and ruggedized industrial floodlights for oil, gas, and petrochemical security perimeters requiring reliable off-grid zero-spark lighting.
High CRI (>80) glare-free stadium and auxiliary training pitch illumination around Education City, Al Rayyan, and Lusail Sports Complex car parks.
