I just got a new Q5 PD30, a new Q5 P3D, and a D10 R2. I have to agree that the P3D beam is fantastic....easily the smoothest and creamiest beam of all three lights. Ring-free and much whiter than the PD30, even though they are both Q5....dunno why. The D10 R2 would be next in terms of the wall shot beam quality, followed by the PD30 with massive ringage. It has less OP on the reflector, I guess for increased throw....but the rings are prominent, and the color is much yellower....not necessarily a bad thing. I'll probably keep it since I like the overall design much better (anti-roll, mild crenelation, better tail design). Anybody know how easily I could get into them and play with swapping out the reflectors and/or modules? Never done that before!
