I was looking for this information a couple days ago. I found this link:
http://giline.versus.jp/shiden/light_e.htm which lists all the light source types, but has only a few examples.
Allakhazam's will have some differences with P99 (intentional or not), but for items that act as a light source it will list light type. For example
http://everquest.allakhazam.com/db/item.html?item=2531 armor of Fennin Ro has "Light: Flameless Lantern" on all pieces, except the helm. I can only assume it's the same on P99.
I tried to find a way to find all items on alla's with "Light: Flameless Lantern", but google wasn't doing it.
