FAA L-810 Dual Fixture Obstruction Light

FAA L-810 Dual Fixture Obstruction Light

AV-OL Series Universal AC or Universal DC Dual Light Fixture

This Avlite dual light fixture is a steady burning, low intensity LED obstruction light designed to comply with FAA L-810 requirements. The model can be used for marking obstacles up to 150 feet (45 metres) above ground which pose a danger to aircraft at night, such as telecommunication towers, wind turbines, buildings and other tall structures.
Avlite’s LED obstruction lights offer an ultra bright, energy efficient and cost effective lighting solution. The light fixture is available in two configurations, universal DC (12–48VDC) or universal AC (110–240VAC 50/60Hz).
The dual light fixture can be configured to different operational states. Both light fixtures may be set to operate steady-burning. Alternatively, the dual light fixture may consist of a main light and a standby light. If the main light should ever fail the standby light will automatically switch on to ensure the obstacle is always clearly marked.
