The AV23 is a low intensity solar powered obstruction light designed to offer users years of maintenance-free operation. The unit is completely self-contained and incorporates a large 10watt solar module, 7.5Ah battery, LED light source and advanced driving circuitry.During daylight hours the solar module will charge the battery through an advanced switch-mode regulator incorporated into the flasher unit. The lantern will automatically begin operation at dusk once the ambient light threshold drops sufficiently.The light is built from heavy-duty cast aluminium - subject to 7-stage powder-coating, and offers users enormous impact and weather resistance.This completely self-contained unit with integrated solar module and battery system saves users considerably in power, cabling and on-going maintenance associated with traditional incandescent systems.The AV23 has been independently tested to be in accordance with the requirements of the photometric and colourmetric specifications for a Low Intensity Type A Obstacle Light.
