The AV425-RF is a robust, completely self-contained LED light designed for a range of emergency aviation applications including runway, threshold, approach, helipad and tactical solar airfield lighting. Fitted with RF radio control, this fully functioning light can be controlled from the tower with no costly cabling or trenching required.Solar Airfield Runway Lighting This solar airfield lighting unit is made from cast aluminium, subject to 7-stage powder-coating in aviation yellow. Four premium grade solar modules are integrated into the assembly and mounted to collect sunlight at all angles.The solar array charges the 24Ah battery during daylight hours, and at dusk the light will automatically begin operation. 16 independently controlled LED drivers within the light optic (patents pending) allow the AV425-RF fixture to operate as an omnidirectional or bi-directional assembly designed to meet the photometric requirements of FAA L861 runway edge and threshold when set to temporary high mode.
