IP = Ingress Protection. Indicates the level of protection for the housing against external influences, in compliance with DIN EN 60529. The first figure describes protection against foreign bodies, the second figure describes protection against water. The higher the individual values are, the higher the respective protection level is.

-20 - 35 °C
Describes the minimum temperature required, so that device life expectancy is not negatively influenced, and functioning continues optimally for as long as possible.
Energy efficiency index
Describes the number of possible operational cycles of the light source, or how frequently this can be turned on and off.
Electrical power factor
Ratio of effective power to apparent power or ratio of power actually taken from the power grid to actually usable power. The ratio derived therefrom determines efficiency.
