The ingress protection (IP) is an internationally standardised code that identifies the resistance of electrical appliances against the ingress of foreign items and liquids, especially water. It is expressed in the so-called IP code, which consists of the "IP" followed by two digits: the first indicates the protection against dangerous contact and foreign objects, the second indicates the degree of protection against water ingress.
Luminous flux is a measure of the total amount of visible light emitted by a light source and is expressed in lumens (lm). Higher luminous flux means higher light output. This parameter is important when choosing a luminaire because it affects how bright the lighting in a space will be.
The length of time (according to the manufacturer) the lightbulb will shine, under the ideal conditions. This value is also affected by how many times it is turned on – frequent switching on and off reduces the lifetime.
