Default MVA halogen bulbs?

I recently just posted a question regarding the replacement of a halogen A4 headlight with a S4 because of a bad seal. Now my passenger low beam has gone out which I attribute to moisture inside the housing. I was checking out replacing my high beams and low beams with a set if MVA 7500k and 8500k. Does anyone have any experience with this company and would they be a good option or should I just say f it and roll with a legit HID conversion?

There is no legit HID conversion. Almost all are made with substandard ballasts and counterfeit lamps.

Even if components came from Automotive Lighting the reflector in a halogen housing cannot give the correct beam pattern with a HID capsule installed.

I really doubt MVA has real 7500K or higher HID capsules. No one markets the metallic salts that ionize at that temperature. Using a blue dye in the glass will raise the color temperature, but will reduce the light output.

The problem to overcome is the reaction of the human eye to higher color temperature light. As the temp passes 5000 K the reaction becomes less with the result that you cannot see as well with bluish light.

If you want HIDs it might be cheaper to sell your car and buy the same model that has the toys you want.

If you insist on HID, buy genuine housings and ballasts. Keep in mind that adding the automatic leveling system is out of the question financially.
