Description
Cold Cathode Ultraviolet Lamp Tube Ozone-Free Cold Cathode UVC Germicidal Lamp for Sterilization Box Bag
Cold cathode lamps are small size, long life, low power. It emits 253.7nm (Non-ozone type) or 253.7nm and 185nm (ozone type) ultraviolet light to kill microorganisms. Therefore, this lamp is mainly used in toothbrush sterilizer and beauty brush sterilizer and other small electrical appliances. It needs only a few minutes sterilization process. There are usually two types used more widely, straight tube and U tube.

uv tube manufacture
The ozone free lamp( Cold cathode germicidal lamps)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.
How UVC Light work
While the Cold cathode germicidal lamps(ozone generating 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.
Cold cathode germicidal lamps emit 254nm(ozone free),or 254nm and 185nm (ozone generating) to kill microorganisms,so they are extensively used in toothbrush sterilizers and operate for several minutes.
