Essentially I want a circle 8-10" in diameter and around its circumference I want a solid beam of light that will travel at most 18-24"
Think kind of like a force field of visible light without of obvious force field bit.
I have been hunting around on the internet and started looking at L.E.Ds and Lasers and thought I might try on here in case someone has had experience with light shaping etc.
Ive attached a cheezy UFO image to give you the idea im talking about with the light (best representation I could find)
