OL800 Solar LED Obstruction Light

FAA L-810 and Low Intensity ICAO Type A/B Applications

The OL800 solar LED is an integrated lighting solution including a high-efficiency LED light source, solar panels and battery.


Per section 13.8 of FAA AC 70/7460-1L: a steady-burning red L-810 is required during construction if the permanent flashing L-864 is not in place. If power is not available, structures should be lit with a self-contained, solar-powered, steady burning red LED light meeting the photometric requirements of an FAA L-810.


Created to meet requirements for FAA L-810, ICAO low intensity Type A/Type B and CAR 621 CL-810, the OL800 is easy to install. It requires minimal maintenance and is ideal for temporary installations like MET towers and during wind farm construction.
