Ultraviolet (UV) Curing Offers Precision and Speed for Critical Manufacturing Applications
Posted by Dave on for ProLampSales
Ultraviolet curing is a process that uses UV light to cure or harden coatings, adhesives, and inks in a wide range of industrial and commercial applications. This technology is particularly beneficial for sectors such as medical device manufacturing, fiber optics, electronics, and lens production, where precise, fast, and solvent-free curing solutions are crucial. How Does UV Curing Work? UV curing is a process that employs ultraviolet light to quickly cure or harden a material, typically...

Whole House vs. Point-of-Use Ultraviolet Water Purifiers
Posted by Nick on for ProLampSales
Ultraviolet water purifiers are effective in disinfecting water by neutralizing harmful microorganisms. There are two primary types — whole-house and point-of-use (POU). Each type has various pros and cons depending on the installation and usage needs. Whole-House UV Water Purifiers A whole-house water purifier treats all water entering the home, providing purified water for all faucets, appliances, and water-based systems (e.g., showers, dishwashers). Even before water gets to the hot water heater, it is disinfected...

How Sediment and Ultraviolet Water Purifiers Work Together
Posted by Nick on for ProLampSales
Ultraviolet (UV) water purifiers and sediment filters can be utilized in an integrated system to provide a comprehensive approach to water purification by addressing different types of contaminants. Sediment Filters Remove Large Particles Sediment filters are designed to remove larger particles from the water. These particles can include dirt, sand, rust, silt, and other debris that may be suspended in the water. The filters typically consist of a porous material, such as spun polyester, carbon,...

Building HVAC Systems Provide An Ideal Opportunity for UV Air Disinfection
Posted by Dave on for ProLampSales
Owners and facility managers looking for a way to disinfect the indoor air in offices, medical centers, retail stores, schools and residential care facilities will find that their HVAC system may provide the safest and most cost-effective approach. Buildings equipped with a ducted heating, ventilating and air-conditioning (HVAC) system are prime candidates for in-duct ultraviolet (UV-C) units that can provide whole-building air sanitizing. UV-C germicidal lamps emit 253.7 nanometer wavelength irradiation that, in sufficient doses,...

Strategies for Reducing Virus Spread in Residential Care Facilities
Posted by Dave on for ProLampSales
In addition to the deadly and debilitating impacts of COVID-19, its spread within communities has also illuminated the inadequacies of basic prevention and control strategies in place at public facilities and institutions. One of the most glaring examples is residential care facilities. There are currently (2021) over 16,000 nursing homes and long term care facilities in the U.S. Of the total confirmed COVID-19 cases in the U.S. as of April 2021, residential care facilities accounted...

Upper Air UVC Fixtures Safely Disinfect Air While Rooms Are Occupied
Posted by Dave on for ProLampSales
Upper air ultraviolet germicidal equipment is designed to provide air disinfection within an occupied space. The louvered upper air units are wall or ceiling mounted above the "human zone" in the space, generally at 7 feet or higher. The usual UV-C 253.7 nanometer (nm) wavelength emitted by the germicidal light bulbs is directed out of the unit by the louvers and into the layer of air at or above the mounting height of the unit....

UV Curing: A Growth Industry
Posted by Dave on for ProLampSales
Dating back to the late 1960's and early 1970's, ultraviolet light was used to cure wood fillers and coatings on furniture. Since then, with the development of a wide range of UV curable materials and specialized equipment, UV curing has grown exponentially - widely adopted in manufacturing, graphic arts, and printing. Technically, UV curing is the polymerization of a coating, adhesive, or ink when it interacts with ultraviolet radiation. This process makes possible rapid drying...

What is the Voltage of Fluorescent and Ultraviolet Bulbs?
Posted by Dave on for ProLampSales
You may have noticed that the specifications for fluorescent tubes, compact fluorescent bulbs, and ultraviolet lamps provide watts, but almost never volts. Why not? Ballasts, invisible inside the fixture, are required for all fluorescent bulbs to operate. Ballasts modify the line voltage they are connected to (120V, 277V, etc.) so the proper current is supplied to the bulb. Because ballasts are hidden, it is easy to assume the bulbs are simply operated directly off line voltage from the...

How UVA Blacklights Help Veterinarians Diagnose Pet Skin Infections
Posted by Nick on for ProLampSales
Blacklights are not merely for special effects and lighting up cool posters. They also have an important clinical use by veterinarians. These bulbs are very common for diagnosing ringworm in cats, dogs, and other animals. The most common tool veterinarians use to diagnose ringworm on pets is a Wood's Lamp, which is another name for the common blacklight bulb with a blue filter. According to Wikipedia, Wood's lamps have been used since 1925 to detect...

What Are Amalgam Fluorescent and Ultraviolet Bulbs?
Posted by Dave on for ProLampSales
The performance of fluorescent tubes, compact fluorescent light bulbs, and low pressure mercury ultraviolet bulbs deteriorates in ambient temperatures that rise above certain design parameters. At high fixture and room temperatures, light output and color characteristics deteriorate. CFLs are particularly affected by this, as anyone who has had a CFL bulb in a porch light or the garage fail on a hot summer day has learned. But this effect on ultraviolet germicidal bulbs can be...

What to Know About Mercury in Fluorescent, Ultraviolet, and HID Bulbs
Posted by Dave on for ProLampSales
Reasonable care should be taken in both the handling of broken light bulbs and the disposal of burned out bulbs that contain mercury. For decades, fluorescent and CFL bulbs have been used widely in commercial and residential general lighting settings, but there has been a vast increase in homeowners, businesses, and institutions utilizing ultraviolet bulbs to purify air and sanitize surfaces due to the COVID-19 situation. Fluorescent tubes, compact fluorescent, UVC germicidal, UVA blacklight, metal...

Overcoming the Unique Challenge of Biofilms to Ultraviolet Disinfection
Posted by Nick on for ProLampSales
While no pathogen has been discovered that is immune to ultraviolet germicidal irradiation, biofilms present a unique challenge due to their structure. They allow harmful microbes a way to protect themselves against ultraviolet penetration and are ubiquitous on Earth. Biofilms are microbial communities in a wet complex matrix attached to a solid surface. The microbes produce polysaccharides that allow them to attach to a surface, and they can be found all over the planet, including...
