The ozone free uv germicidal lamp emits 254nm UV light to kill microorganisms directly, ultraviolet photons harm the DNA molecules of living organisms in different ways. In one common damage event, adjacent thymine bases bond with each other, instead of across the “ladder”. This “thymine dimer” makes a bulge, and the distorted DNA molecules will not function properly.
While the ozone generating uv germicidal lamp gives out 185nm UV light to react with oxygen gas in the air or water to form ozone. Ozone is able to destroy cells of microorganism, and it also serves as a kind of strong oxidant to kill biological tissues of microorganism. And based on UV photolysis, our ozone generating UV bactericidal lamps could completely decompose oil, remove fume and other peculiar odor.
Warning:
UV-C radiation output of uv germicidal lamps is harmful to unprotected eyes and skin.
Appropriate safety wear must be worn, or installations completely screened.
