The ozone free 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 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.


 Wide application

Lightbest germicidal lamps are commonly seen in various water treatment systems to deal with sewage,

waste water, fish tank water, drinking water, ultrapure water, purified water, swimming pool water and

so on.



  Easy Installation and cost-effective

Lightbest germicidal lamps could be made with different pins for different installation conditions: 2P

double ended structure is easy to install, 4P single ended ones save a lot of space, and SP double

ended lamps, resulted from instant heating and discharging of filaments, can be started instantly.

Lightbest germicidal lamps have a power range of 4W-80W, and its useful life is as long as 10000 hours,

which helps reduce waste and energy use.


Various Lamp Bases

Lightbest germicidal lamp bases can be made of different materials,such as ceramic, aluminum and plastic.

Ceramic has better heat transfer performance and eco-friendly, aluminum and plastic ones with lower cost,

you can choose suitable ones according to your demands.
