You could say that this is debatable. In order for you to have decent lighting on the road, you have to up the wattage of the bulb. And most likely you'll end up buying new bulbs every other week.
If you must use the projectors, I recommend using either Piaa or Raybrig bulbs. I was using Piaa's Hyperwhite 80/55 watt bulbs with no problem. They looked good on the car, but didn't do well when the weather got foul. If you want, match them up with a set of fogs to get more light on the road.
Other than that, I'd suggest going back to stock.
