With the normal sized LED's that I have worked with such as the XML, the larger the reflector, the better the throw. (in general)You lose half of your light to either side of the lens to start off with.
The same physics apply for LEDs. A bare die is basically a 1 1/3 inch "beam" with a divergence of ~160 degrees. Expanding 3x to 4 inches cuts divergence to ~53 degrees. If you're more familiar with radians That's about 1 radian (1000mRad).
The emitting area is the limitation here. You cannot tame it. Physics will win EVERY time.
I realize this thing is a huge emitter and will have a wide output no matter what, but I'm thinking it can have better throw with that larger reflector and lens.
Worth a $10 dollar experiment for sure...
