This is a 4 pin bulb that is 22 1/4” long. Ultraviolet light is invisible to the human eye.
Never look at the bulb when lit – it is harmful to the eye.
Ultraviolet light is invisible to the human eye. It is part of the electromagnetic
spectrum that lies beyond the purple range of the visible spectrum. The ultraviolet
(or UV) spectrum has wavelengths between 100 and 400 nanometers (nm). The UV spectrum is
further divided into wavelength ranges named UVA, UVB, UVC:
UVA: sun tanning, testing, inspection, insect traps, stage effects, blacklight, phototherapy* (315-400nm)
UVB: sun burning, inspection, analysis, testing, phototherapy* (280-360nm)
UVC: germicidal (253.7nm), ozone producing (185nm)
UV-C light is germicidal – i.e., it deactivates the DNA of bacteria, viruses and other
pathogens and destroys their ability to multiply and cause disease. Specifically,
UV-C light causes damage to the nucleic acid of microorganisms by forming covalent
bonds between certain adjacent bases in the DNA. The formation of such bonds prevent
the DNA from being unzipped for replication, and the organism is unable to reproduce.
In fact, when the organism tries to replicate, it dies.
