You know filtering is a scientific term, right?

Yes, but the moon does not scientifically filter the sunโ€™s sunlight in ways that should affect vampirism

Ahem:

Compared with sunlight, the wavelength of full moonlight is generally centered around 400โ€‰nm (580โ€‰nm for the sun) with a very low energy level (0.2โ€‰lx or 0.0024โ€‰ฮผmolโ€‰mโˆ’โ€‰2โ€‰sโˆ’โ€‰1). The red:far red (R:FR) ratio of sunlight during the day is more than 1.2, while that of moonlight is between 0.18 and 0.22

Intensity (in lumens) is also hugely different (0.09 vs 3,955). Over a 40,000:1 ratio!

Why not? We don't need to use sunscreen on full moons, and we can safely stare at it.

Well, yeah, but will it kill a vampire?
