    Building HVAC Systems Provide An Ideal Opportunity for UV Air Disinfection

    Building HVAC Systems Provide An Ideal Opportunity for UV Air Disinfection

    Posted by 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

    Strategies for Reducing Virus Spread in Residential Care Facilities

    Posted by 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

    Upper Air UVC Fixtures Safely Disinfect Air While Rooms Are Occupied

    Posted by 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....

    A Maintenance Schedule Ensures Long-Term Performance of LED Lighting Systems

    A Maintenance Schedule Ensures Long-Term Performance of LED Lighting Systems

    Posted by on for ProLampSales

    While sellers of LED lighting often promote the savings benefits of reduced maintenance because of the long life of LED light sources, this can obscure the fact that maintenance remains a key function for the successful operation of LED systems. Maintenance of all types of commercial lighting systems includes re-lamping, power supply management, controls optimization and fixture cleaning. LED systems are no different, even if the specific tasks are not the same. Whether maintenance is...

      UV Curing: A Growth Industry

      UV Curing: A Growth Industry

      Posted by 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...

      How to Evaluate LED vs. HID Horticulture Lighting

      How to Evaluate LED vs. HID Horticulture Lighting

      Posted by on for ProLampSales

      A 2018 study by the Lighting Research Center (LRC) at Rensallear Polytechnic provides detailed guidelines for comparing LED and HID light sources for use in commercial greenhouse and other horticulture facilities. The report is also a cautionary advisory on transitioning to LED based only on the criteria of improved energy efficiency and longer lamp life compared to HID. Scope of LRC Study Commercial environmentally-controlled greenhouses in the U.S. account for nearly 900 million square feet...

      What is the Voltage of Fluorescent and Ultraviolet Bulbs?

      What is the Voltage of Fluorescent and Ultraviolet Bulbs?

      Posted by 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

      How UVA Blacklights Help Veterinarians Diagnose Pet Skin Infections

      Posted by 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...

      The Difference Between Ballast Factor and Ballast Power Factor

      The Difference Between Ballast Factor and Ballast Power Factor

      Posted by on for ProLampSales

      Reading fluorescent ballast and HID ballast specification sheets can make your head hurt. Case in point: ballast factor vs ballast power factor. Ballast Factor Affects Light Output Ballast factor is a number normally between 0.70 and 1.2. This number is a multiplier applied to the rated initial lumens of a fluorscent or HID light bulb. The result tells you how many lumens are actually delivered from the bulb-ballast system. In some cases, the result will be...

      What Are Amalgam Fluorescent and Ultraviolet Bulbs?

      What Are Amalgam Fluorescent and Ultraviolet Bulbs?

      Posted by 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...
