The low beam is about half of the overall beam. The shutter chops off the top.
The idea in a projector is to do exactly what you are not liking (concentrate light in front of the vehicle) so as to avoid blinding oncoming drivers. You would be amazed how much improvement you will get by simply bringing up the angle of the light a touch off the road and in front of the vehicle. Be careful as even with the stock bulbs people will get annoyed. Ideally as a driver I would want the light to be basically straight out of the bulb, however to appease the fellow drivers maybe a 20% down angle is best (the patch of light on the road extends maybe 100-150 feet)
