I dont know what the iodide does in the lamp or for the lamp.. sorry should have been more clear but here is the answer..

The Iodide comes from on of the Iodides used to produce light, along with the Mercury and Argon gas. The Iodides are usually of rare earth soft silver metals;
Scandium Iodide, Thorium Iodide etc. The combination of these Iodides gives the lamp characteristics you want

A second opinion is always good.

I guess Wikipedia doesn't get everything right either. I believe Mercury make a whole lot more sense.
