This is a collection from a few lighting vendors. Most of them are for outdoor lighting. While these are mostly direct links to the IES downloads, it's probably a good idea to look at the lamp they are representing first so you know what result to expect.

Lamps from Gotham Lighting(need to goto each lamp model itself on this site)
Holophane Lighting
Mark Architectural Lighting
Peerless Lighting Lamps(Like Gotham above you need to goto each lamp and dig up its IES data
