The CALZONI SEAL II is a Portable Lighting System for airfields based on LED. It is modular to accommodate stand-alone landing zones with incremental levels of operational capabilities.

The light unit comprises of the runway lights (white), approach lights (white), threshold lights (green), end lights (red), and taxiway lights (blue).

The system modules can consist of any type of the above lights in variable quantity,
depending on the operative configuration.

Each light uses an LED lighting source (high flux type) and dedicated lenses, as to increase the photometric characteristics and lifetime. This reduces the power consumption and the maintenance costs against the traditional incandescent lamps. With the LED source the system becomes NVG compatible and with the LED IR source the system conforms for "covert" operations.

The system has several supply sources covering operational scenarios: batteries, solar panels, and external power (e.g. diesel generator). The lighting unites are battery powered for emergency operational situations and wireless configurations. The batteries inside the light units are rechargeable from the system transport container provided with battery charger. In the wired configuration the light units
are connected by cables and the control can also be done through the cable or wireless. The batteries are automatically recharged by the power provided by the solar panel or the external generator through the cables. The lights, lightweight and robust, are designed to be easily and quickly utilized also from not trained operators. The system can be configured in different modules to be tailored for different missions. Accordingly the system is supplied in special anti‐shock plastic resin containers, with 6‐8 lights each container, manually transported or trolleys for complete configurations.


The system constitutes an expansion in terms of capabilities of the SEAL System used by the Royal Australian Air Force and is based on portable lights, supplied by internal batteries, available with different configurations of luminous source.
