HID Ballast is a high intensity lamp
High Intensity Discharge full name is often mentioned in our daily mouth HID, HID, mainly by HID bulbs, ballast, power adapter cord and its annexes, the HID bulb lamp filled with xenon majority (etc. Xenon) with iodide and an inert gas. Just turn on the power of the moment xenon lamp, ballast will instantly boost the car's 12V voltage to 23000V, take advantage of this high-intensity HID bulb voltage-activated intense light generated between the poles, lighting the lamp to achieve high brightness.
Analog style ballasts use capacitors, coils, and resistors to convert the DC power from the car to AC power that the ballast runs on. These types of ballasts are the "old school" type before digital electronic parts were used; they are cheaper to produce and sell. Unfortunately, these types of ballasts are not as reliable since it relies on the power from the car which may not be always constant; constant fluctuations of power to the HID bulb will reduce the life of the bulb prematurely. Digital style ballasts use electronic circuitry as the main internal components along with parts from an analog ballast; these types of ballast often have various safety features to maximize longevity and minimize wear on the parts. Constant and stable power can be delivered to the HID bulb and protection features are usually a standard with digital ballasts. Digital ballasts are quieter, more efficient, and can typically provide power to the HID bulb to create a brighter output.
While digital HID ballasts are usually much more efficient, low quality digital one may operate worse than high quality analog ballasts. Analog ballasts typically do not create excessive heat and may only reach up to 31 degrees Celsius (87.8 degrees Fahrenheit) whereas low quality digital ballasts may produce up to 70 degrees Celsius (158 degrees Fahrenheit). A high grade digital ballast will produce as much as heat as an analog one. HID ballasts are usually very bulky, but newer versions are becoming smaller and smaller thanks to better technology and relocating the igniter outside the ballast instead of inside.
One of the best things with the 35W/55W AC Slim Ballast is that they have got a warranty one year, with this you do not have to worry of any Ballast that you have purchased. Once you have purchased it you are then provided with an installation manual that assists in installing it. The hardware tools are also made available for you with the purchase.
