Leading Light: Headlight bulb reviews
On the right choice of them depends on whether you will be able to see the dangerous obstacle in time and not to lose control of the car from the glare of the headlights of the oncoming car. Thus, unlike a number of other components, the choice of which most car owners are at the mercy of service men, car lamps - a product that many drivers buy themselves. It is not easy to choose from the variety of headlight 9007 bulb comparison on the shelves those that are optimal in their characteristics.
Most leading manufacturers have in their range of full lines of lamps for different purposes. These include standard lamps, lamps with improved visual comfort, all-weather, higher power and lamps with increased luminous efficacy. In order to understand which ones will do the job and which ones will not, you need to fully test the lamps on a number of key indicators: light intensity, geometry and, therefore, the light intensity at certain points and color temperature. If there is no such a possibility, we can trust our own experience or trust the claims of manufacturers.
We decided to present you the lamps with the most common base H4, and from the whole range of lamps to choose two types - standard and lamps of increased visual comfort. The essence of the first follows from the name: these lamps are ordinary halogen bulbs and are similar to those supplied to the assembly lines. The so-called white light of the second type of lamps is more comfortable for the eyes than the standard. But when choosing these lamps, it is important to remember that in rainy weather visibility with them is worse, because the white light is more glare from wet surfaces and even from individual raindrops.
Test of LED headlight bulbs
At present, there are already four types of light in car headlights. These are the usual halogen lamps, efficient xenon, LEDs and exotic laser light sources.
Not far off the competitive confrontation between LEDs and laser
A comparative test of LED headlight bulbs is correct, comparing with existing types of lighting. Although tests by Audi have proved the excellent prospects of the laser, the development is still "raw", the automobile concern plans to install it on rare sport copies. Engineers were able to achieve an excellent range of illumination when using it - up to 600 meters. It is possible that in 2-3 years, many production cars will be equipped with such sources, and then include a novelty in the test.
So, let us consider the characteristics of LED lamps in comparison with existing competitors. In the parameters we will try to take into account all the important consumer properties, not only brightness, power and other technical factors.
Benefits of LEDs
A car equipped with such a headlight, while losing the technique with a quality, installed in the factory xenon in terms of brightness. But, LEDs significantly reduce the risk of glare, and this is an important factor in traffic safety. Very good indicators of power consumption. Comparative test shows that the car when the light is on will feel less load on the generator and the battery.
As the test shows, the LEDs installed as a source of headlight, meet the parameters of 5000-6000°K. This is pure white light, which is considered by medics to be comfortable for perception by the human eye. Low heat dissipation contributes to the transparency of the headlight glass, the lamps also extend the life of the inner surface.
The long service life and amazing reliability of LED lamps leave no chance for competitors. Headlights equipped with LEDs will work many times longer than xenon. If you take the usual halogens, the ratio of operating life is 1:100. In general, the test proves the advantage of the new technology on the main parameters.
