  • Description

    The L550-864 is a medium intensity red flashing LED obstruction beacon designed for reliable day and night time marking of structures that represent a hazard to aviation. It incorporates the benefits of advanced LED and control to meet the challenges of the most demanding applications.

    Though it was designed for lighting wind turbines, the L550-864 may also be used in other industries where red obstruction lighting is needed. Its light physical weight and single cable / single controller design makes it ideal for structures that require multiple red flashing beacons.
