Rated power

The power normally consumed by the lamp during operation. This parameter is often used to evaluate the overall brightness of the glow, especially in the case of lamps for headlights (see "Purpose"): such a specific parameter as the luminous flux, firstly, is less familiar to ordinary car owners, and secondly, in its characteristics are not always indicated. However, it must be remembered that only lamps of the same type (see above) can be compared with each other in terms of power consumption. different types can differ markedly in efficiency and luminosity. But what this indicator directly affects is the power consumption of the lamp and, accordingly, the load experienced by the generator or battery. Modern car lamps have a power of up to 100 W, such power consumption is normally tolerated by the on-board network in normal operation. However, the lower horsepower provides some fuel savings.

Colour temperature

The colour temperature of the light emitted by the lamp. The overall colour of the glow depends on this indicator; and note that the higher the colour temperature, the more “cold” the light looks, the closer it is to blue and blue. Traditional incandescent bulbs produce warm light at 2500-3000K, 3000-3500K can be described as "slightly warmer than neutral", neutral white corresponds to temperatures of 3700-4500K, higher values correspond to cooler shades, and temperatures over 5000K characteristic of lamps with a blue (blue) colour of the glow.

Note that in this case the colour temperature of the lamp itself (more precisely, its filament or LED element) is indicated, and not the actual shade of the glow that it will give out; for the difference between these indicators, see "Glow colour". Also note here that it is possible to evaluate the shade of light by colour temperature in headlight lamps (see "Intended use"), for which the white colour of the glow is claimed. At the same time, this indicator has a very practical meaning: the warm colour of the light is considered optimal in wet weather, the neutral one gives the highest visible brightness, all other things being equal, and the cold “long-range” one can be subjectively pleasant for some drivers, and can also be used as an element of external tuning.
