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...
