Light colour:
The colour of the light, e.g. red, green, blue, yellow, white or warm-white is given here.
The colours white or warm-white of the light are assigned to colour temperatures in Kelvin [K] as listed below.
2600 K to 3500 K is called warm-white, approximately the colour of filament bulbs and halogen lamps.
> 3500 K is called white.

Power consumption:
Specifies the total power consumption of the article.
If an article is offered as a set comprising a transformer, cabling and several luminaires, for instance, then the total power consumption of all components is given here.

Life expectancy :
In the case of lamps, the average life expectancy is given. This is the average life of individual lamps running under standardised conditions. In the case of LED lamps, the life is deemed expired when the light flux [lm] drops to 50% of its initial value. The life of all other lamps is deemed expired when the lamp is dead.

Beam angle:
The beam angle indicates the extent to which the light is bundled or scattered. The wider the beam angle, the more the light is scattered. The smaller the beam angle, the more the light is bundled.

Equals filamant bulb:
The brightness of this article equals the brightness of a filament bulb with the power given here.
The brightness of this article equals the brightness of a filament bulb with the power given here.
Savings:
The saving when using the article instead of a filament bulb of equal brightness is given here. This calculation includes both the power consumption and the buying cost. The following is assumed in the calculation of savings:
Electricity tariff: € 0.18/kWh
Life expectancy of a filament bulb: 1000 hours
Cost of a filament bulb: € 0.80
The formula for calculating the savings is:
Savings = (equals filament bulb – power consumption) * life expectancy * electricity tariff – price of this article + (life expectancy /life expectancy of a filament bulb * cost of a filament bulb)
Your savings may be different if your individual values are different from our assumptions.
