So where am I to find the purest spot 26mm lense. I am making a light to be used at a distance of about 18 inches and I need a spot of about 2-3 inches with very tight cut off of light. I don't want any flood if at all possible. I am currently using a K2 Led and a 3 deg lense which gives about a 4 inch spot but I would like it to be a little tighter if at all possible. Thanks

I would suggest an aspheric with a cree led, and use a piece of black tubing on the bezel to block off any remaining sidespill. you should be able to get a perfectly round no sidespill beam.
