Lore questions Why aren't vampires killed by moonlight?
A common idea of the world of vampires is that vampires are killed by sunlight. This concept was popularized by the 1922 vampire movie Nosferatu.
In some lore, the reason is about magic: The sun represents symbolic purity, is a divine stellar object. The moon is not, it is for demons and other unholy creatures. That's why vampires can't venture out on a sunny day in this magic oriented lore.
In some lore, it is the ultraviolet rays from the sun that kill vampires.
The moon has no light of its own. It merely reflects sunlight. Then, why aren't vampires killed by moonlight?
The moon absorbs most of the light that hits it. Only about 13% is reflected. Sunlight is 400 000 - 1 000 000 times more intense than the light from a full moon. Vampires might be somewhat weak supervillains, but they aren't that weak. That could be the reason to why moonlight works fine for vampires in this more scientific oriented vampire lore.
