This and all the loses in brightness by using optics.It can't be done. Your limitation here is emitter size, and those 100W LED are actually an array of 10x10 1W dies. The effective emitting area is enormous compared to a single die. You can add a gargantuan focusing optic (parabolic mirror or convex lens) to bring the divergence down, but that means a very large initial beam diameter. Therefore, you will NEVER get a beam like the one in your video. Physics says it's not possible. Not with that LED.
