As requested by some of you guy's a quick Photometric light setup....
ok ....ive just made a simple box room with a couple of shelve's in so you can see the light distribution.
1 : in the top view add a photometric free piont light in the position that you need it (make sure you do it in the top view so when the ies data comes in its round the right way).
2 : move the light up into the position of where your going to put your model of you spot light. at this stage the light is still round .....meaning that it has no ies data attached to it, so if you was to render at this stage the light would almost act like an omni light and have light coming out all around it.
3 : Time to add the ies data to the light.
right click on the link and save target.

4 : Select your light and go to the modify stack, there you will see a label called Distribution, choose Web, once you do that you will get another rollout called Web Parameters, click on where it say's Web file and choose the ies file that you downloaded.
As the file is loaded you will notice that the shape of the light will change from round to a rain drop shape...... this is because the light now has the data writen in to the ies file or the Distribution data file........ you can see from the shape of the light where the light is going
hit render and see what you get.
copy the light into the spot light positions or where you want light to be.....
you can adjust the intensity as you would pretty much a normal light....
like everything you will have to play with these lights but you do get a real world light distribution which looks very cool......
here is the final scene

also you can get a lot of light data from here http://www.erco.com
I hope this has been of some help ...
