The brightness is 10X better vs. the xp3. I can leave all the lights on in my house and you can still see the gobos crystal clear. You barely need any fog to see the beam even in a well lit room. I believe with the xp3, the lights need to be pretty dim. To be honest, I was originally looking at 4 xp3 units at stores and thought they were nice. But the auto's just do so much and have such a professional quality. And yes you can adjust the angle of the beams to either a smaller or larger room.
