According the American ANSI and IEEE stand-
ard, surge voltage resistance required
for outdoor lighting surge current load kA. Surge protection devices
must correspond the testing standard IEC 61643-
11 and must able arrest surge currents sever-
al thousand amps multiple times without destruction.
However, decisive importance for the protection ac-
tion that the protection level the surge protection
device below the surge voltage resistance the
lights and the LED driver. Powerful lightning current combin-
ation arrestors can arrest the energy-rich currents.
The luminaire standard "Fpr 60598-1: 2012-11 Lu-
minaires Part General Requirements and Tests",
Point 4.32 specifies: "Surge protection devices must
meet IEC 61643.

According the testing standard, each protection
device must have thermal monitoring and must be
isolated safely there defect.Installation location the lightning and surge
protection
The use surge protection required for safe opera-
tion."
If there direct lightning strike the mast lumin-
aire, large portion the lightning current will flow
directly into the earth, creating potential difference to
