1, the normal flux
2400 lumens HID light flux is about three times more than ordinary halogen lamps; the use of 1,000 hours of maintenance rate was 70%. Basically, the HID lamps on the market in the brand new state can reach this target, some even brighter (because the power of design more than 35W). However, some HID lamps in use for some time there will be significantly decreased energy. The main reason is because the smaller the power lamp aging, but some is because the supercharger start voltage and operating voltage are lower than the rated parameters (23000V/85V).
2, the color temperature
color temperature is a measure of the standard color temperature, not the measure of light intensity. Halogen's color temperature can be 2300K to 7000K; HID lights from the 4200K color temperature to more than 8000K; lights higher the temperature, its penetration of the fog and rain the worse (the less bright).Manufacturers such as Philips has produced only the highest color temperature of 6000K Xenon lights.
The following is the performance of different color temperature:
Effect of light color temperature of light
3000K yellow light, strong penetrating power
4200K white with yellow, the original car with xenon lights
5000K light all white, EU maximum color temperature
6000K light all white, slightly blue
6500K in the sun during the day
7000-8000K white with blue in the clear
8000K blue above, poor penetration
More than 6000K bulb problems commonly seen in addition to poor penetration, the other is the color temperature drop problem. Non-large production rate of decline in lamp color temperature is different, some may be reduced by half to 50%, 10000K change 5000K, white yellow light.This install lights in the side after six months to put a new one light bulb to clear the other side of that yellow light bulb, and in general users are not satisfied with this quality bulbs.
3, the life
users willing to spend large sums of money for HID lamps, in addition to the benefits because it is bright enough, but also because of its long life, up to 2500 hours, compared with halogen lamps (500 hours) long and 4 times more vehicle life of 15 years, a considerable (European standard). Parameters of a lifetime to do this, basically require the transfer of patents, as well as advanced production equipment and technology can achieve. Some light bulbs will be broken in less than a week (light bulbs black), that is because the smaller manufacturers in the production process caused by the air bulb gruel. In addition, when the modified light bulb, even if some errors can lead to reduced lamp life, for example, between the ceramic tube and the tube there is a certain distance, the deviation from this distance will lead to reduced lamp life.
4, the temperature inside the tube
the arc led by high-pressure xenon gas discharge light-emitting elements, high temperature light bulb, the bulb at the bottom to 400 degrees Celsius. Thus modified material must be used when special materials are high temperature. Also, due to the high voltage sake, but also high resistance of the material must be selected to prevent the discharge lead to high short-circuit, resulting in lack of energy, not to affect the other car lights are electrical appliances and so on.
converted into H1, H4, H7 and other types of HID lamps, the shape has changed compared with the original, to determine the new pin is fully suitable for halogen lamp assembly of the focus, in addition to the design With high-end test equipment to be outside, in the production of special equipment needed to detect whether the tube axis.This is why the market is also H1, HID lights, mounted on the same car, the effect will be shown by different reasons.
