I was messing around with one of my lights today and I put a project optic infront of a 5x cree r2 beam and at 50ft I got 5 discrete 5" tall emitters as the beam. I don't havew a lux meter but I'm thinking its going to be crazy high.
Don't know if it'll be crazy high. All depends on the diameter of the lense, the quality of the lense, what LEDs you are using and what current they are being driven at.
