Light 'cone'

Does anyone have any tips regarding accurate depiction of the cone of light coming from a lamp? I've modelled a Hunza outdoor lamp that has a fairly narrow beam and my efforts so far have resulted in the beam being too wide.
I tried placing the emitter surface as deep as possible up the light, to try and narrow the beam, but it's not that great. Perhaps a smaller emitter disc ( ie lamp surface) might help?

Thank you.
Do I just plop the IES file into the emitter properties section of the MXM and the rest is taken care of? Am I right in making the emitter a flat disc the same size as the front element of the lamp or should it be smaller?

I'll look at the documentation. Looks like I need a sphere.

It says 'small' but not how small. I guess I should just experiment.

IES needs small sphere, like 0.5 cm in diameter os so.
