the application and lamp power);
- 12 V storage battery (with a capacity ranging from 120 to 144 Ah, depending on
the application).
The structure of the light fitting comprises;
- casing and dissipater made of aluminium;
- cover in grey coloured (RAL 7035) shockproof polycarbonate, stabilized against
deterioration caused by UV radiation;
