Solar Obstruction Lights – GEO300

The GEO300 solar LED light provides in excess of 5km visible range (flashing), and is suitable for a variety of applications including taxiway, general hazard, barricade and low-intensity obstruction lighting.

Designed to be maintenance-free and have a service life of up to 10 years, the popular GEO300 model is available in either steady-on or flashing operation. The light is simply switched ‘ON’, and the unit is ready for immediate operation. Once installed, the Geo300 requires no operator intervention.

The internal solar module charges the battery during daylight hours, and at dusk the light will automatically begin operation once the ambient light threshold drops sufficiently. The battery is housed in a sealed compartment allowing it to be changed after years of service.
