No, DC-Fix kind of diffuses the beam. Kind of makes the hot spot spread out more and have a smoother transition from the hot spot to the spill. Check out this thread. There are some good before and after shots of some folks using it. I use it in a lot of lights that I use around the house and out in the yard. I love the stuff. If I can find a few pics of before and after that I have I will post them here shortly.
