Arctic Kit: electric device, thermostatically controlled, that heats the area near the prisms (inset fixtures) or the external glass lens (elevated fixtures) favoring the melting of the ice and/or snow; thus avoids the light beam obstruction with a behaviour similar to a traditional halogen lamp. 40 VA per plug.

Monitoring: electronic device that returns information of open circuit at the secondary of the isolation transformer in case of failure of a luminous LED source or control board.
