I know Starlights normally in air- and light-tight aluminum packaging. And for good reason: by light, particularly UV light lose the chemicals their effect and after buckling often happens nothing - and then possibly when you need it!
So for a party where one anyway all uses up OK, but sont for me a no-go. And since it is not in the product description's from me only one star!
Better to spend a little more and buy quality of Cyalume!
