Why do so many people writing vampire stories assume that ultra-violet
light is sufficiently like sunlight to destroy vampires? Indeed, it
would make more sense for natural sunlight to carry with it some kind of
*mystical* energy (ki or magic or whatever), and that energy is
disruptive to the energies which animate the undead.
It really depends on how the vampires in a specific story actually work. If
they're undead cursed to drink blood for having forsaken the Light, like in
White Wolf's Vampire: the Masquerade, then only true sunlight harms them,
because it's symbolic. If they're either a different biological species (as
in Blade) or vampirism is actually caused by some sort of scientific virus,
then it makes perfect sense for UV rays to harm them. Since there's no such
thing as "vampire canon", it's up to the author to decide what works.
