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.

Minimum chromaticity refers to the lowest level of colour tone that a light source can offer. This value is important for environments where soft and gentle light with a lower colour temperature is desired, such as relaxation rooms or living rooms where a relaxing atmosphere is desired.

Maximum chromaticity refers to the highest level of colour tone that a light source can achieve. This value is crucial for spaces where brighter, crisper light with a higher colour temperature is required, such as work areas, kitchens or places where maximum visibility is needed.

The Colour Rendering Index (CRI) is a measure of how accurately a light source displays colours compared to sunlight. A higher CRI value means that colours will look more natural under that light. This parameter is important in shops, galleries and anywhere where an accurate and realistic display of colour is required.

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.

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.
