  I’d assume the intensity of a lamp and the sun is quite different

    What makes you think the sun has a massive UV-C output?

      I’m thinking a big flaming nuclear fusion reactor creates more power than some lamp

      Honestly I have no idea how the intensity compares but I’m just saying without numbers you can’t really compare it to a lamp. Especially if that lamp assumes that some person might put their hand under it.

        I am not the one who made the initial claim, but if you want numbers: about 2 % of sunlight is a shorter wavelength than UV-B or about 70 W/m². If you want the same irradiance from a lamp, all you need to do is get closer, unless the lamp is really weak. 5 seconds is simply nothing.
