My L7 and 8NX were not sealed. The usual sales outlet for those types of packaging usually have the product away from where they can get handled casually and have bits get swiped out of the box.
Current retail hang packages, where the light is in a blister pack wrapped in the paper card extolling the virtues of the light are sealed.
If you want to know if you are getting the whole deal as Surefire shipped it the best bet is to check the website for a description of the package contents.
