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.

Lifespan B3

Guaranteed lamp life according to B3 standard. In fact, this is the longest time that the lamp can continuously work with a 97% guarantee (it is impossible to provide a 100% guarantee in principle). This parameter is measured as follows: a test batch of lamps is used until 3% of them fail, the resulting time is indicated in the characteristics.

Other things being equal, longer-lasting lamps naturally cost more, but longer service life compensates for this disadvantage. Separately, we note that you should not confuse the guaranteed service life with the manufacturer's warranty — the conditions and warranty period may be different even for lamps with the same B3.

Light colour

Standard lamp glow color.

It is worth considering that in this case we do not mean the own shade produced by the lamp (see “Color temperature”), but the light that will be produced “ultimately” during normal use of the lamp. For example, in auxiliary models (see “Purpose”) intended for brake lights, the glow color is usually indicated as red - this is the standard color for “stops”. In this case, the lamp itself can have a color temperature of about 4000 K (neutral white). Similarly, models used in fog lights can be yellow, in turn signals - also orange, etc.

If we talk about the head light, then it is most often made white, and in such models the shade can be determined by the color temperature (see above). If the characteristics of the “head” lamp indicate a different color, this most likely means that it has a painted bulb, and the light produced by the headlights will have the same shade. Note that we are talking specifically about shade, and not about full-fledged light: for example, purple lamps will illuminate the environment with white light with a slight bias towards cool colors. At the same time, such lamps themselves will look purple. Such features are useful primarily for external car tuning.
