Good group there. Nice job!
It's interesting that of all the lights you shot, only the A9s totally blew out your camera's ISO setting and washed out the center of the beam in the photo where you can't see the tree, only a white spot in the middle. It looks like if you kept the A9s on that spot too long, you'd light the tree on fire.
It's even more interesting to take a close look at the house on the left side of each photo, and you can see that the A9s also throws the biggest and brightest and
whitest side spill as well. Most of the other lights turn the house blue.
I've got an A9s Special Edition myself, and I'm mighty impressed with the throw as your pics obviously indicate, but the beam for me is a little narrow so I'm about to order the OP reflector for it.
I'm confident that it will still be a great thrower, but a slightly wider hot spot will be more useful to me.
Thanks for taking the time to post the pics, and if those pics don't help to sell a
bunch of A9s's, I don't know what will.
