The CombatTactics Magazines did publish more details and photos about WeaponLights then I've ever seen published before. I'm sure it's a useful resource to some. Of course, it should be your only resource.
The Tactical Products Catalog does a very good job of showing some of the different things that SureFire have been up to as well as helping people learn more about their WeaponLight products normally considered too complicated.
