and importing of mercury vapor ballasts into the United States for replacement or for use in new luminaries. High voltage is fed to the lamp from the ballast by using the phenomenon of superimposing a low energy high voltage pulse. An electric current in the gas energizes mercury vapor which delivers ultraviolet radiation through discharge process and the ultraviolet radiation causes the phosphor coating of the lamp inner wall to radiate visible light. Airport Lamps Ballasts Fixtures Fluorescent H.I.D. Heard my first arc source lamp go bye bye today. Low pressure UV lamps may be used for disinfecting purposes, curing nails and dental fillings, or water purification. The lamp had to be designed in a sphere because after the metal cooled when the lamp was turned … 175 to 400 watt metal halide lamp ballasts can power mercury lamps of the same wattage, but the reverse is not recommended. Our companies offer a superb line of UVC emitting compact germicidal lamps for applications in small spaces. Mercury vapor technology was developed throughout the 1800s in England and Germany. Holiday Incandescent LED Lighting Controls Miniature Bulbs Miscellaneous Neon Photo, Stage & Studio Receptacles Reference Materials ReferenceMaterials Rope Lighting Shatter Resistant Sockets Specialty Swimming Pool Transformers Tungsten Halogen(Quartz) "/> The type of lamp used in printing applications is usually a medium pressure, linear (straight tubes), mercury vapor arc lamp. High-efficiency low-pressure mercury lamps offer 30% to 60% higher output at a spectral output of 254 nm and are ozone-free. Put them in a sealed plastic bag and take it to your local waste facilities for recycling. If this was not used in the light bulbs and T8 light bulbs (tube Lights), there remained a risk of current rising to a destructive level. This device is known as a Ballast. Low pressure sodium lamps were invented first in 1920 by Arthur H. Compton at Westinghouse. ignitor - A device, either by itself or in association with other components, that generates voltage pulses to start discharge lamps. The electric current excites the mercury vapor in the tube, generating radiant energy, primarily in the ultraviolet (UV) range. The clear mercury bulb has a bluish green appearance and the Deluxe White has a higher color rendering. These lamps are consistently a favorite product among our clients. Mercury lamps get dimmer over time and rarely burn out, so it is wise to replace them and restore light level. Home Solutions UVC Germicidal Lamps UV Germicidal Lamps Low Pressure Mercury Lamps Compact. Also saw some of the glass that came out of an enclosed housing. They produce light when an electric current passes between two electrodes (also called cathodes) in a tube filled with low-pressure mercury vapor and inert gases, such as argon and krypton. Special types such as U-shaped lamps, electrodeless UV lamps, surface lamps or contour lamps for special applications complete our product portfolio. Softglass lamps have a germicidal efficiency of 30% and can operate on lower current (between 180 and 425mA). Compact fluorescent lamps (CFLs), which are popular in many households, contain 4 mg of mercury on average. Applies to ballasts designed for operation on 50 Hz a.c. supplies in association with high pressure mercury vapour and low pressure sodium vapour discharge lamps. When heated up the metal would vaporize and the lamp would glow yellow. The lamp ballast’s primary function is to limit the lamp current to its … But there are plenty of other types of lamps that contain more of the toxic chemical, including neon and black lights, fluorescents, tanning bed lamps, sodium and mercury vapor lamps, metal halide and mercury short-arc lamps. Medium Pressure UV (MPUV) Lamps . Do not use a vacuum cleaner. To achieve full rated light output and rated lamp life from a fluorescent lighting system, a ballast’s output characteristics must precisely match the electrical requirements of the lamps it operates. Medium pressure UV lamps are also useful in UV curing processes as well as microbial disinfection and germicidal applications. In the event of a mercury ballast failure, users should contact their sales representative to discuss lighting system replacement and upgrade options. Light bulb Depot, 16 locations across the nation and shipping to your door or job site. Our standard low pressure mercury lamps offer the highest efficiency with 40% of the lamp’s electrical power converted into UVC radiation at 254 nm, while high-output mercury lamps provide approximately twice the UVC output. Ballast is still used in bulbs and tube lights to avoid current rise in the lights. The fluorescent tube is essentially a low pressure mercury discharge lamp. MPUV lamps are primarily used in the waste water disinfection industry and in marine ballast water treatment systems. LED, HID lights and fixtures. Medium pressure UV lamps cure inks and coatings instantly. Mercury Vapor lamps feature low initial cost, but have higher operating costs than HPS or Metal Halide due to its lower efficiency. Ballast Wiring Diagrams for HID ballast kits including Metal Halide and High Pressure Sodium Lighting ballasts. It is a photochemical not a heat process. Without some means of limiting the lamp current, the lamp would quickly be destroyed. This ban includes fluorescent (linear and U-tube), compact fluorescent (CFL), mercury vapor, metal halide, high-pressure sodium and low-pressure sodium lamps. This lamp has a highly stable output predominantly at the 253.7 nm Mercury line. Low-pressure Amalgam lamps also deliver powerful germicidal properties for instant sterilization and disinfection of water and can be found in many water sterilization applications. Like all fluorescent lamps, low-pressure tanning lamps have a ballast to start the lamps and limit the flow of current. Even if cold and more normal in size, I once broke a … Thus, some ballasts have a separate circuit that provides a low voltage to heat the lamp electrodes during lamp starting and typically during lamp operation (Hammer, 1995). Identify what type of lamps you have. USHIO Germicidal lamps are Low-Pressure Mercury-Arc lamps that emit radiation peaking at 253.7nm(UV-C). Low Pressure Sodium Low pressure sodium (LPS) lamps are grouped with HID lamps, If a lamp breaks, ventilate the room for 30 minutes and remove the parts, preferably with gloves. It specifies requirements for the characteristics of ballasts which are essential for correct lamp operation, and for the safe and satisfactory operation of the ballasts themselves. Ballast Low-pressure mercury vapor lamps cannot be directly operated on a 115 AC power line. MPUV lamps emit significantly more UVC energy than low pressure ultraviolet lamps (LPUV) which allows for higher flow rates of water disinfection while maintaining a compact geometric footprint. Lamps get dimmer over time and rarely burn out, so it is wise replace. And the lamp would glow yellow metal halide ( probe start ), mercury vapor lamps can not directly.
