Custom Designed 254 nm UV Lamps

254 nm UV lamps describe the most common type of UVC germicidal lamps used to disinfect the air, water, and surfaces.  Ultraviolet (UV) radiation emitted in the UVC range, between 100 to 280 nm, is proven to be most effective at eradicating harmful bacteria, viruses, and pathogens.  UVC lamps are designed to emit UV radiation in the range of 254 nm quickly and effectively penetrate the cells of harmful microbes, altering the DNA and rendering these cells unable to replicate, thus considered harmless.

UVC lamps are used in many environments and applications such as in hospitals, in patient rooms, and operating rooms, to disinfect medical equipment and supplies.  Germicidal UVC lamps are also used to sterilize the air in many industrial, commercial, and residential environments including in HVAC units, furnaces, and air conditioning systems.  Many surface sterilization systems utilize the power of UVC radiation as well as water disinfection UVC systems. 

254 nm UVC Lamp Design and Engineering

254 nm UVC lamps are designed in basically three different glass types including: 

• Soft Glass

• Fused Quartz

• Synthetic Fused Quartz

Soft glass provides a lower-cost option for powerful UVC germicidal lamps that transmit UVC radiation at 254 nm only.  

Fused Quartz is available in two types, “L” for low ozone emission or “VH” for very high ozone emissions. “L” fused quartz 254 nm UV lamps by LightSources are designed to emit up to 90% of the UVC energy at 254 nm.  VH lamps can emit both 185nm and 254nm with custom engineering available to splice both L and VH ratios to meet specific germicidal requirements. 

Synthetic fused quartz lamps provide superior UV transmission at 185nm for very high ozone-producing applications. 

LightSources offers both 185nm and 254nm UV lamps for germicidal applications worldwide as a leading global supplier of UVC sterilization lamp solutions.
