How do UV lights kill bacteria?

At certain wavelengths, UV is mutagenic to bacteria, viruses and other microorganisms. Particularly at wavelengths around 260 nm–270 nm, UV breaks molecular bonds within microorganismal DNA, producing thymine dimers that can kill or disable the organisms. Mercury-based lamps emit UV light at the 253.7 nm line.
