UV Sterilization Lamps That Outperform Comparable Lamps

UV sterilization lamps are used worldwide to improve health and wellness with effective germicidal properties. UV radiation emitted at specific wavelengths of 254 nm instantly eliminates harmful microscopic organisms such as bacteria and viruses immediately upon exposure.  UV radiation emitted at 185 nm produces ozone, which is a natural air purifier and deodorizer, eliminates volatile organic compounds (VOCs) and foul odors from the air.

UVC germicidal lamps are used in many environments including residential, commercial and industrial air treatment systems.  UV lamps improve air quality in many environments including:

• Residential property
• Commercial businesses
• Industrial applications
• Hospitals
• Nursing homes
• Schools
• HVAC air treatment systems

It is important to select high-quality UV lamps from a reputable lamp manufacturer to obtain long-lasting, effective UV air sterilization performance. LightSources is recognized worldwide as an authority on UV lamp engineering and manufacturing, supporting OEMs large and small with proven UV lamp solutions.

High Pressure UV Curing Lamp Experts

Ultraviolet (UV) radiation causes many useful chemical reactions, with purposes far beyond giving a suntan.  UV light, emitted within a specific range of wavelength, can cure and instantly dry inks, glues, adhesives and various coatings providing a smooth and hardened finish.  The proper UV lamps must be used, manufactured with experience and knowledge of the various functions provided by the different wavelengths of UV emissions. 

UV curing can be used for curing surfaces in several industrial and manufacturing processes.  High pressure lamps, also referred to as Metal Halide lamps, are used in many industries such as automotive, aerospace, advertising, medical, food and beverage, cosmetics, and many others, for curing various surfaces quickly and effectively.

UVA / UVB / UVC – Various UV Wavelengths are Used for Specific Purposes

UV radiation is emitted at different wavelengths, measured in nanometers, which means a billionth of a meter, and is the common measurement for wavelengths of electromagnetic radiation.   Visible light is within the range of 400 to 700 nanometers.

Ultraviolet light can be broken into three different categories, UVA, UVB and UVC, ranging between 200 to 400 nm.  UVA light has a wavelength with ranges between 315 - 400 nm, while UVB falls into the mid-range of 280 – 315 nm and causes most sunburn, and UVC makes up the shorter wavelengths ranging from 200 – 280 nm.

UVB and UVC light are most commonly used for sterilization and purification purposes in medical and environmental applications, with variations available in low pressure (LP) amalgam lamps, medium pressure (MPUV), and high pressure output lamps.

LightSources is the Expert on High Pressure UV Lamps

High pressure UV curing lamps emit shorter wavelengths peaking at 254nm, and raging all the way to 365nm.  The typical high pressure lamp emits radiation within this range, although the shorter waves at 254nm are ideal for germicidal functions, including water, air and surface sterilization.

High pressure UV lamps can also be used in higher wavelengths ranging from 385nm to 417nm, and are used in reprographics, providing superior print quality for long lasting durable results.   The engineers at LightSources are not limited to the typical manufacturing standards; we can alter the spectral output with additive compounds, harnessing additional peaks of UV radiation.  We are experienced at using gallium-iodide at 400 – 450nm, and iron-iodide for desired ranges between 350 – 400nm.   Other variations of additives are available upon request, depending on your application and desired results.

LightSources and our affiliated companies represent the leading high-tech designers and manufacturers in the lamp industry today.  Our products are used world-wide in a multitude of applications and industries such as our UV polymer curing lamps that offer patent-protected, OEM-oriented solutions.  Please contact us to learn more about our large selection of specialty custom and standard lamps.

Study on Effectiveness of UVC Lamps Used for Sterilization

The PYHS.ORG website recently cited a study out of Washington State University that looked at the effectiveness of UVC lamps on sterilizing organic fruits and vegetables.  It showed that ultraviolet C (UVC) light does destroys foodborne pathogens on the surface of certain fruit.  Their complete report is published in the International Journal of Food Microbiology.

Reacting to a concern from organic food growers regarding safe alternatives to chemical sanitizers, a team of WSU food safety scientists started a study using UVC light, which has shorter wavelengths than UV-A or B light.  One of the researchers, Shyam Sablani explains, "UVC radiation is present in sunlight; however, it is completely absorbed by the ozone layer and Earth's atmosphere."  He went on to say that, “It has germicidal properties and can be effective against bacteria, mold and viruses."

To determine how effective the UVC light destroyed listeria and E. coli, fruits such as apples, pears, strawberries, raspberries and cantaloupe were exposed to various doses of the light.  Results showed that the UVC light inactivated up to 99.9 percent of pathogens on smoother skinned fruit such as apples and pears but only 90 percent of pathogens on the rough-surfaced fruit.  They also discovered that listeria was more UVC resistant than E. coli.  More studies are being done to find ways to increase the effectiveness of UVC light on fruits with rough surfaces but overall the scientists felt that UVC technology is promising.
