New bulbs, hotspot is off

Hey guys, I'm running 6.0 MH1 projectors, and the other day I swapped out my bulbs (the old 3five bulbs, ACME now) with the newer XB35 H1 bulbs.

It seems like the hotspot is off and the cutoff isn't as sharp anymore. I had trouble getting the bulbs in, getting the two little tabs to go in where the old bulbs seemed to go in with a satisfying fit, while these don't have the same feel of being 'locked in' to the projector. Could it be the bulbs are defective? I read around sometimes the new XB35's need to have the base sanded down a little to fit right, but I don't want to do that
