HID Kits 101 / FAQ

dangers. Most sellers are selling DC HID Kits at low prices to win the buyers. However, most consumers will never know what they are getting is an inferior product that would never be used by OEM manufactures. What is the difference between (Cheap) DC and (Quality) AC kits? AC and DC describe the electrical method the conversion kit operates. One of the most common questions about HID ballasts is what is the difference between AC and DC ballasts, which is better and why. Let's first look at what AC and DC is and then which technology is better. DC, or direct current, is just that: electrical current that runs in one direction from a power source (ballasts in our case).

We would like to get a few things straight in this article. DC direct current works the following way: an electrical current runs in one direction from a ballast a power source. It uses a constant steady positive voltage in a circuit.

This type of the current is distributed unevenly on the electrical components. The DC ballast moves the positive ions to the negative side only. This increases the temperature of the bulb one side is always hotter than the other and shortens the lifespan of the light. ACor alternative current how to get rust out of concrete, sends power through a circuit alternating between positive and negative voltages, as a result ,the electricity flows in both directions.

An AC ballast reverses the polarity on the same electrode with the help of a reverse switch, so there is an equal distribution of ions. This is a really good question. It is all about the Xenon ballast which converts the direct current into alternative. The AC power allows to put less strain on the components of the HID light bulb while producing the same and even better light output.

This type of conversion kits benefits from lower operating temperatures in addition how to get rid of white background on pictures longer term color accuracy.

The main reason is its low price. The DC ballasts are very simple to manufacture since they do not need to convert the power into AC. This kit burns out faster and car enthusiasts may end up spending more money replacing the faulty parts. The AC sets require inductor coils and voltage regulators inside the ballasts to convert the current, thus these lights are more expensive on the market. Does it really matter?

What is the difference?

AC vs DC (We only sell AC Ballasts): Both types of ballasts take the DC power from vehicles and power the HID bulbs for light. The difference in these ballasts is in the type of electricity being outputted to the HID bulb. AC ballasts output AC power, while DC ballasts output DC power. DC lamps are used, as is much easier to make an electronic, accurate power-regulated ballast, DC. On fluorescents HF AC is preferred (as it spread the current towards the arc perimeter, so lower UV selfabsorption), but this is unuseable for HID due to mechanical resonance issues. HID Kits also know as HID Conversion Kits or Xenon Lights are plug and play kits designed to replace your factory halogen bulbs with HID Lights. HID Kits provide 3 times more light output compared to stock halogen bulbs that are currently equipped in your car. Each HID Kit comes with two HID Ballasts and two HID .

As discussed on the issues page , HID bulbs are arc lamps that run a fixed current through two electrodes in a sealed quartz capsule. Because the input power from the car electrical system is nominally 12V DC, there are two stages required to output the necessary power to an HID bulb:.

However, Chinese cost-cutters, in an effort to produce increasingly cheaper ballasts, figured they could get rid of the second step and feed DC directly to the bulb.

The result is lower component count, but a bulb that will burn out very quickly due to rapid erosion of the positive electrode. Some Ebay Sellers are starting to market the difference, but price is almost always the most reliable indicator. Price is usually a giveaway, though some manufactures have figured this out and are now up-pricing DC ballasts to make huge profits.
