Warm-white does not always need to be associated with high costs. The lamp provides the same light colour as a conventional lamp, with the advantage that it consumes less energy. When dimmed, the colour of light changes from 2700K to 2200K, which is the same effect as when dimming a filament lamp.

CRI= Colour Rendering Index (colour rendering index Ra). Describes the quality of artificial light compared to daylight (Ra=100) . The higher the value is, the more natural the rendering of illuminated colours.
Energy efficiency index
Describes the deviation of the colour point or colour consistency that may arise within several batches of the same products. (Unit: SDCM)
Rated value luminous efficacy
Describes the number of possible operational cycles of the light source, or how frequently this can be turned on and off.
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.
Dim to warm
Weighted energy consumption
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.
Also called radiation angle, describing the angle between two points, at which luminosity falls to 50% of the maximum value.
