The LED E27 bulb with head mirror imitate the classic light bulb look and has the same light colour - with the added advantage of consuming less energy. The retro-oriented look makes this bulb a real eye-catcher.
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.
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.
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.
