OL800 Solar Obstruction Light

The OL800 is a fully self-contained solar obstruction light targeting the FAA L-810 and ICAO low-intensity Type A/B red categories. The entire system — high-efficiency LED array, solar panel, sealed lead-acid battery, and control electronics — is packaged in a powder-coated aluminium housing with a UV-resistant polycarbonate lens. Installation requires no power cabling: mounting uses a 3- or 4-bolt pattern at a 200 mm bolt circle, making it genuinely suitable for temporary structures such as construction cranes, MET masts, and temporary weather-monitoring towers where running power cable is impractical.

The battery system is sized in two variants: the compact model achieves 5–7 days of autonomy without solar charge, and the large model achieves 16–19 days — the latter is a meaningful margin for sites with extended overcast periods or dust-accumulation conditions common in Gulf desert environments. Charging uses Maximum Power Point Tracking with Temperature Compensation (MPPT-TC), which adjusts the charge algorithm as panel temperature rises, preserving efficiency under high-ambient-temperature conditions.

Optional GPS synchronisation coordinates flash timing across multiple units on a wind farm or construction site without any wired interconnection between towers. The OL800 is rated IP68 for full immersion, withstands wind loading to 161 mph (72 m/s), and carries Intertek certification covering FAA, ICAO, Transport Canada CAR 621, and Australian CASA requirements. The light output is 209 candelas (red), with an optional infrared variant capped at 70 cd to meet additional NVG standards.
