I think it’s some spiritual mumbo jumbo about raw sunlight vs filtered moon(sun)light

[-] RampantParanoia2365@lemmy.world 5 points 2 years ago

You know filtering is a scientific term, right?

[-] southsamurai@sh.itjust.works 2 points 2 years ago

Well, yeah, but will it kill a vampire?

[-] Sylver@lemmy.world 2 points 2 years ago

Yes, but the moon does not scientifically filter the sun’s sunlight in ways that should affect vampirism

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

Ahem:

Compared with sunlight, the wavelength of full moonlight is generally centered around 400 nm (580 nm for the sun) with a very low energy level (0.2 lx or 0.0024 μmol m− 2 s− 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!
