Re: 10,000 cp spotlight?
Very cool photos indeed! Thanks for posting them!
It is also interesting to note the beam shape. If you look closely it seems to converge maybe fifteen feet or so out of the light, and then start spreading out again. I have noticed this in some other photos as well, and I am sure it relates to that ellipsoidal vs parabolic discussion.
