Ballast operating principle: when connected to power, in an instant through the use of low-voltage transformer volt car power rose to more than 2 million high-voltage pulse activated xenon lamp xenon bulbs in the electric arc produced in the 3000-12000K color temperature, thus activating the xenon lamp lighting. This transformer is what we call a "ballast." The color from the light to see the sun at noon was slightly purplish blue. It burns completely with the traditional tungsten light technical principles to derail the new century and modern lighting and innovative products.

Full name of the High Intensity Discharge is often referred to in our daily mouth HID , high-pressure gas discharge lamp, mainly by the HID lamp, ballast, power adapter cable and its annexes, HID lamp bulb is filled with most of the xenon gas (Xenon ) with iodide and other inert gases. Just turn on the power of the moment xenon lamp, ballast to boost the car's 12V transient voltage to 23000V, the use of this high-intensity lamp voltage-activated HID light in the issue between two poles, lighting the lamp to achieve high brightness. HID ballast can be regarded as the fuse, the quality will affect the xenon lamp to function and life, not because of the immediate temptation to lose the greater the price.
