Philips Mercury Vapor 175-Watt High Pressure HID light bulb is ideal for use in landscape lighting, dusk to dawn, roadway, parking lots, floodlights and security fixtures. You can't just slap a random incandescent together with a random mercury-argon bulb. Metal halide Incorrect bulb usage can result in damage to the fixture or the bulb's exploding. For more information, see Ultraviolet Radiation Burns from High Intensity Metal Halide and Mercury Vapor Lighting Remain a Public Health Concern (December 6, 2005). You should now test the mercury-vapor lamp. This energy (UV light) is then absorbed by a thin coating of white phosphor on the inside of the bulb. However when checking the ballast, any burn marks, swollen casing, or (in the case of “ye old” magnetic coil ballast) leaking oils are obvious signs of failure. Breathing elemental mercury into your lungs is generally more dangerous than if you ate the mercury or absorbed it through your skin. Mercury vapor lamps are gas discharge lamps that uses an electric arc through vaporized mercury to produce light. Pros: The best Mercury Vapor Bulb on the market, the Megaray, puts out 400 microwatts of UVB. 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. I've NEVER had a bad bulb come on and off. The site is secure. Manufacturers of mercury vapor lamps are responsible for compliance with all applicable requirements of Title 21 Code of Federal Regulations (Subchapter J, Radiological Health) Parts 1000 through 1005: 1003 - Notification of defects or failure to comply, 1004 - Repurchase, repairs, or replacement of electronic products, 1005 - Importation of electronic products. Before sharing sensitive information, make sure you're on a federal government site. Strip lights contain low pressure mercury vapor which when iodized (electric current passed through it) emits UV light. These lights are typically controlled by a photocell that turns the light on at dusk. The first course of action is to simply change the bulb. Mercury short-arc bulbs; and; Neon bulbs. The protective bulb filters out harmful ultraviolet light and keeps the mercury gas contained if the inner chamber breaks. Mercury Vapor Bulbs. Plug it into an outlet and take measurements of the voltage that goes between the capacitor lead that is black and the COM. A fluorescent light bulb (also referred to as a "lamp") is a gas-discharge bulb that uses electricity to excite mercury vapor. The advantage is that it produces a bright white light, with relatively long life. Just as you will have to replace standard incandescent bulbs in your habitat due to vibration failure, so will the self ballasted needs to be changed*. 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. But it has to be designed, too. It uses an arc through vaporized mercury in a high pressure tube to create very bright light directly from it's own arc. Wattage can range from under a hundred watts to a few kilowatts. As with fluorescent lights, mercury vapor lamps require a ballast to supply the proper voltage and regulate the current to the electrodes. Confirmed that this 60 W germicidal bulb is fake (no UV emissions). Despite the mandate, there are plenty of old outdoor mercury vapor lights still in use in the United States. Turn on the switch. The voltage should read 15 VAC, but it should ramp up to 130VAC within 5 to 10 minutes. A mercury HID bulb exhibits a blackening at the end of the arc tube. This will tell you whether the lamp and the capacitor are good. Identify what type of lamps you have. Their Venture ballasts (BV-V90D6112K) are $37. This filament is the weak point in the bulb. They should only be installed in light fixtures that are fully enclosed by a lens of glass or plastic, or used only in areas where people will not be exposed to UV radiation if the outer bulb breaks. Checking a common light bulb using a multimeter on the ohm scale. The ballast of a light fixture ignites the vapor inside the bulb. The excited mercury atoms produce short-wave ultraviolet light that causes a phosphor to fluoresce, producing visible light. I have a great mercury vapor bulb that I use for my bearded dragon. High pressure sodium, and mercury vapor. Reptile UVA UVB Mercury Vapor Bulb,Heat Lamp for Reptile and Amphibian Such as Tortoises & Bearded Dragons,PAR 38,E26,100 Watt,Six-Month Guarantee 4.1 out of 5 stars 63 $29.99 $ 29 . Since the light emitted by a mercury-vapor light has a blue tone, this needs to be accounted for, or color- … This is enclosed by an outer glass bulb that filters out harmful short-wavelength ultraviolet (UV) radiation. However, if the outer bulb breaks, and the inner tube continues to produce unshielded light, intense UV radiation is emitted. Large high intensity discharge bulbs such as metal halide lamps are bigger and if these break in a closed environment, the gas release is much worse. Check whether it still hums. Once inhaled, the mercury vapor … While environmentalists have promoted them as safe, and the US government has given them a de factor mandate and subsidy by banning incandescent bulbs, there are still concerns among the public about the risks of having hazardous materials in their homes. Sunlite 03675-SU MV100/DX/MED H38 Mercury Vapor Lamp, 100 Watts, Medium Base (E26), ED17, 6000 Hours Life, 4000 Lumen, Coated White Finish 4.4 out of 5 stars 150 $9.70 $ 9 . 1) Self Ballasted Mercury Vapor (SBMV bulbs) bulbs have a filament inside that works as a ballast. This will tell you whether the lamp and the capacitor are good. As they strike mercury atoms, a mercury electron is liberated at a frequency representative of mercury’s spectral line, which is 253.7nm. 391.200 Warning Statement in Advertisements for High-Intensity Mercury Vapor Discharge Lamps that are not Self-Extinguishing (21 CFR 1040.30(e)(3),), Guidance for Industry and FDA Staff - Addition of URLs to Electronic Product Labeling, Compact Fluorescent Lamps (CFLs) - Fact Sheet/FAQ, Getting a Radiation Emitting Product to Market, Records and Reporting (Radiation-Emitting Products), Importing and Exporting Electronic Products. The mercury vapor lamp is a high intensity discharge lamp. “R” type light bulbs do not have a self-extinguishing feature. According to the United States Government Printing Office, the Energy Policy Act of 2005 prohibited the manufacture and importation of mercury vapor light ballasts after January 1, 2008. Top of page. Mercury Vapor Bulbs will supply UVA, UVB, and heat for your bearded dragon… making them a kind of “all in one” option. The heavy duty transformer or ballast is also long lived if the bulbs are changed out before they burn out. Mercury Vapor bulbs have an arc tube that contains a minute amount of liquid mercury under pressure that vaporizes with an electrical charge. If your pet doesn’t really bask, he may not actually get enough UVB from one of these. Ballast is necessary to run the 175w mercury vapor bulbs that are used for underwater lights. If you have a liquid-in-glass thermometer, it is important to be able to tell if it contains mercury. The mercury vapor lamp is a high intensity discharge lamp. Fluorescent tubes and compact fluorescent light bulbs (CFLs) can release sufficient mercury vapor to cause poisoning. A projector lamp contains about 30 mg of mercury and it is in vapor form and under pressure, if the lamp explodes it is released into the room in vapor form. Using a mercury vapor lamp with a ballast that was made for a higher wattage bulb might damage it or cause it to explode. Added to this is a small amount of mercury. Observe the interior gas tube for any signs of discoloration. To minimize exposure to mercury vapor, … The light fixture should turn on. If the liquid is not silver in color, it does not contain mercury. 70 High-pressure-sodium lamps and metal-halide lamps … Should I change the light bulb, sensor or the whole light? I've also never had a bad photocell come on and off. With headlines circulatingabout mercury in CFLs, the initial freak-out moment after breaking a bulb is understandable. If the reading is not between five and nine volts, replace the ballast. They typically have spikes through the UV spectrum; so although not necessarily a health risk, it is not as consistent as other bulbs. Any level of mercury exposure carries potential health concerns, but due to the small amount of mercury and short duration of exposure, a broken CFL is not likely to present any significant risk to you or your family, Rogers told Earth911. This ban is ridiculous and no one in their right minds would of ever thought about passing this law in the first place. The difference in UVB is enormous. They provide both UVB and UVB rays. The bulbs have an inner quartz tube containing the mercury vapor discharge. Return fluorescent bulbs to the socket if they were removed to reach the starter. If the ballast is bad, then the needle won’t move. With the small arc size and high power, the arc is extremely intense. Use UVB Mercury Vapor basking lights with caution. Cover the sensor completely with a dark cloth so that no light can get to any part of the sensor. In industrial settings, things are a little trickier. Mercury Vapor Bulbs. Likewise skin aborption of liquid mercury is insignificant compared to inhaling mercury vapor. Why is It Important to Clean Up a Broken CFL Properly? A high pressure sodium bulb (or a mercury vapor bulb) may be installed only in a fixture intended for it, including matching bulb wattage rating. A few simple steps can help. Mercury is an essential ingredient in all energy efficient lighting technologies, including compact fluorescent bulbs. If so, it sounds like you’re in need of a great mercury vapor bulb for your bearded dragon! While the content of 'bound' mercury is always the discussion about the risks of CFL bulbs, relatively little study of mercury vapor in lamps has been done, primarily because they weren't used in the home before. Check out their 100 Watt version here! Compact fluorescent lamps (CFLs), which are popular in many households, contain 4 mg of mercury on average. Compact fluorescent bulbs save energy but they also contain mercury, a toxic metal. A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. Use UVB Mercury Vapor basking lights with caution. Test the ballast's voltage with a multimeter. I've been in maintenance for many years myself, and I've rebuilt more of these than I can count. They give off heat, visible light and UVB rays. They found that the mercury concentration could reach as high as 50,000 … UV exposure at this level can cause eye and skin burns, blurred or double vision, headaches, and nausea. Tungsten (except for its long time constant) is a good fit for these applications. Testing the Mercury Vapor Lamp. Home, Business, and Entertainment Products, Recalls, Market Withdrawals and Safety Alerts, Home, Business, and Entertainment Products, Radiation-Emitting Products and Procedures, Mercury Vapor Lamps (Mercury Vapor Light Bulbs), Ultraviolet Radiation Burns from High Intensity Metal Halide and Mercury Vapor Lighting Remain a Public Health Concern, Federal Food, Drug and Cosmetic Act (FFDCA), Chapter V, Subchapter C - Electronic Product Radiation Control, Applicability of the Performance Standard for High-Intensity Mercury Vapor Discharge Lamps (21 CFR 1040.30), Mercury Vapor Lamp Products Radiation Safety Report, Guide for Preparing Annual Reports on Radiation Safety Testing of Mercury Vapor Lamps, Quality Control Practices for Compliance with the Federal Mercury Vapor Lamp Performance Standard (PDF Only), CPG Sec. Spilled mercury has a characteristic appearance. It is slightly more expensive, but some advantages make it worth using: Mercury vapour bulbs last longer than heat bulbs and fluorescent bulbs. However, if the outer bulb breaks, and the inner tube continues to produce unshielded light, intense UV radiation is emitted. Identify what type of lamps you have. (These are conservative estimates based on comparison to a bulb with 5 mg of mercury.) They either stick on or they stay off. The best fluorescent on the market, the Reptisun, puts out 66. Such a fixture will have the matching ballast in it. So they give off both heat and the necessary UV rays, making it a two-in-one package. It also needs to be underlined that mercury is not the only evil in the mercury filled lamps, but other chemicals present in the bulbs have the potential to cause sufficient damage to health. Under normal operating conditions mercury vapor lamps provide efficient, long-lasting sources of light. The ballast sends electrical power to the electrodes, which excites the gas and makes it glow. Pull the bulb straight out of the fixture. Since another function of sunlight is heating these “cold blooded” reptiles, some new types of bulbs, called Mercury Vapor bulbs, create both heat (infrared radiation) and UV rays. Despite the mandate, there are plenty of old outdoor mercury vapor lights still in use in the United States. It uses an arc through vaporized mercury in a high pressure tube to create very bright light directly from it's own arc. Newer bulbs and ballasts have quick-start technology that uses a small internal transformer to generate enough current to heat the filaments of the bulb. Using too small of a ballast will result in lower light output and can shorten the life of the bulb. When a bulb breaks in your home, some of this mercury may be released as mercury vapor. Ultraviolet radiation burns from high intensity mercury vapor light bulbs are a public health concern, especially in schools and other indoor facilities where the light bulbs may be subject to damage. This is why the CFL works. It has a bluish green appearance and features a low initial cost. This is different from fluorescents which use the mercury vapor arc to create a weaker light … Mercury short-arc lamps are used for special applications, such as search lights, specialized medical equipment, photochemistry, UV curing, and spectroscopy. It also lasts a year instead of 6 months. So if the lamp is connected directly to a constant-voltage source like the power lines, the current through it will increase until it destroys itself. The bulb is filled with argon and mercury vapor at low pressure. CFLs also use the same technology as the linear fluorescent tubes we … Philips Mercury Vapor lamps last at least 24,000 hours. By this point, most lamps have lost at least 40% of their original light output. In addition, mercury vapor lamps must comply with radiation safety performance standards in Title 21 Code of Federal Regulations (Subchapter J, Radiological Health) Parts 1010 and 1040.30: 1010 - Performance standards for electronic products: general, 1040.30 - High-intensity mercury vapor discharge lamps, An official website of the United States government, : The https:// ensures that you are connecting to the official website and that any information you provide is encrypted and transmitted securely. Under normal operating conditions mercury vapor lamps provide efficient, long-lasting sources of light. If inhaled in vapor form it is readly absorbed into the blood 80% absorption. Adjust the multimeter to measure frequency and replace the ballast if the reading is not between 20 and 50 kilohertz. If the ballast and capacitor are both ok, and the bulb is fairly small, there'll be somewhere around 120 volts present at the socket. Top of page. If the liquid is silver in color it might be mercury. But clean energy expert John Rogers is here to ease your mind. Take one or two bulbs out of the fixture if it is a multi-bulb light. It can be difficult to know if you are exposed to harmful levels of UV radiation exposure because the symptoms can take several hours to appear. Compact fluorescent lamps (CFLs), which are popular in many households, contain 4 mg of mercury on average. This is different from fluorescents which use the mercury vapor arc to create a weaker light that mainly creates UV light to excite the phosphors. “You’re talking u… If the light comes on and doesn't flicker continuously, the starter was the problem. (These are conservative estimates based on comparison to a bulb with 5 mg of mercury.) If you’re using a digital multimeter, often the digital readout will possibly list a “1” when it doesn’t find a measurable resistance. Mercury short-arc bulbs; and; Neon bulbs. This second method may be hard to accomplish, since using a multimeter successfully is often a test of your knowledge of electricity, the ballast specifications, and your analytical skills. Once a new lamp is installed, the metal halide bulb will light and come up to full brightness. The tube contains mercury, of which only a very small amount is initially in vapor … The outer bulb may be clear or coated with a phosphor. UV exposure at this level can cause eye and skin burns, blurred or double vision, headaches, and nausea. If you’re still unsure your ballast has bit the dust, then … On the flip side, mercury vapor bulbs are more expensive, stronger, and tend to last longer. While this limited exposure is usually considered safe, a buildup of mercury … The mercury vapor lamp works by creating an electric current to mercury vapor within a sealed glass jacket. What To Do If Your Dusk To Dawn Fixture is Erratic Electrical Question #1: My dusk to dawn light has become erratic, coming on at dusk, staying on a while, going out, coming back on for a few minutes, going out, coming on for a while, going out. Providing 160 Watts of UVB, this bulb is ideal for Buyer’s Tip: Like this bulb but need something less strong? However, mercury-vapor lamps are falling out of favor and being replaced by sodium-vapor and metal-halide lamps. Attach the multimeter's leads to the sockets at the ends of the ballast. The dominant emission (>90%) from these lamps is UV-C energy. You can find ballast for $30 to $40 on the internet. Mercury is a naturally occurring metal that is in many everyday products, albeit in tiny amounts. If you’re looking for an all-in-one kind of bulb or simply know that you prefer Mercury Vapor Bulbs, then I definitely recommend checking out this one from Mega-ray. The outer bulb can also be coated with phosphor to diffuse the light or change its color. The lamp needs to … The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger glass bulb. A typical fluorescent lamp is composed of a phosphor coated glass tube with electrodes located at either end. Mercury Vapor Bulbs also tend to be more expensive, longer lasting, and significantly stronger than fluorescent UVB bulbs. However, this is not the correct repair. Why is It Important to Clean Up a Broken CFL Properly? Mercury vapor lamps are bright, long-lasting light sources that are often used to light large areas such as streets, gyms, sports arenas, banks, or stores. It generates both heat and a good level of UVB and at last a lot longer than a straight UVB bulb of any sort. CFLs and the other light bulbs listed above contain a small amount of mercury sealed within the glass tubing. *,Eš Úè…}ÑÕÅ�.»ëxœ³½±ÕÕ~À}î,ğWõ­o´ÂFeØH.’lU`‡7�²¾6. The mercury vapor lamp is a negative resistance device. 99 It can be difficult to know if you are exposed to harmful levels of UV radiation exposure because the symptoms can take several hours to appear. The Bulb The most common problem with a high pressure sodium light is the bulb. This is caused when metal vapors in the lamp are expired from heat or burning, and the lack of a particular mixture in the arc tube renders a different color. The sensor has to be in its socket to test it as it needs power to it to operate. Plug it into an outlet and take measurements of the voltage that goes between the capacitor lead that is black and the COM. Manufacturers of electronic radiation emitting products sold in the United States are responsible for compliance with the Federal Food, Drug and Cosmetic Act (FFDCA), Chapter V, Subchapter C - Electronic Product Radiation Control. This means its resistance decreases as the current through the tube increases. When the mixture is energized (excited) it creates a glowing plasma of electrons that pass through the mercury vapor. As a metal halide lamp ages, it will require a greater load to maintain illumination. When a bulb breaks in your home, some of this mercury may be released as mercury vapor. Cover the sensor completely with a dark cloth so that no light can get to any part of the sensor. The Maine Department of Environment Protection conducted experimental trials to measure how much mercury was released when fluorescent bulb or CFLs were broken inside moderate sized rooms. ... How do I know if my fluorescent starter is bad? However, while you should take precautions to clean up mercury vapor bulbs carefully, the actual threat in domestic settings in minimal. If you’re looking for an “all-in-one” kind of lighting situation, you’ll want to go with mercury vapor bulbs as they supply UVB, UVA, and heat to your bearded dragon. The .gov means it’s official.Federal government websites often end in .gov or .mil. The transformer limits current (at a variety of voltages, settling at 55V) and the ignitor spikes a 3000 volt pulse onto the HPS bulb to initially strike the arc. Mercury vapor lights consist of a gas-filled glass chamber, protective glass bulb, electrodes and a ballast. Yes, I know that they're not 'regular' light bulbs. There are two types of mercury vapor light bulbs sold in the U.S. Mercury Vapor Bulbs: This option might be better than the other two. ��ëí¢ÙæY@åüşÀU§HBíÏ¿úó£‹Ö*š)%@‚:D±H„PP˜ƒºa•r ®ıNY¿IDJ€! From what you have described it sounds like you have installed lamp socket adapters that have a photocell in each unit, therefore the first unit will go on and produce light that will cause the other two photocells to sense the light and react as if it were daylight. Cons: It needs to be about a foot away from your Beardie, so you may have to get a stand. The ballast in an HID lighting system requires a capacitor, this is a current limiting device that prevents too much amperage to be delivered to the HID bulb. Additionally, their wavelengths are typically shorter than sunlight, and that can potentially cause cell damage & photo-kerato-conjunctivitis. High pressure sodium, and mercury vapor. Examine the bulb for signs it has burned out. Testing to see if it is good or bad. Originally they produced a bluish-green light, but more recent versions can produce light with a less pronounced color tint. Needless to say, you don't want to put any other kind of bulb there. Mercury-vapor lamps were the first commercially available HID lamps. That said, they’re best used as basking bulbs, because the heat and UV rays are highest right under them. The best way to reduce the risk of burns is to use fully-enclosed fixtures or self-extinguishing “T” type mercury vapor light bulbs in facilities where the public can be exposed to the UV radiation from a broken bulb. Your HPS (High Pressure Sodium) lamp has a ballast made of a hefty transformer, capacitor and "ignitor circuit". Conversely, mercury-vapor lamps have a glow-phase and a glow-to-arc phase transition which has a very high "negative resistance" response. The bulb is comprised of an inner tube, called the arc tube, and an outer jacket (or bulb). You should now test the mercury-vapor lamp. I ordered from a company in Texas to make sure that I received them by Memorial Day weekend. My dragon is in brumation right now, and his fixture is available. Identifying Lamps that Contain Mercury "Mercury Use in Lighting" [PDF] is a Fact Sheet prepared by IMERC that summarizes the use of mercury in lighting devices, such as fluorescent lamps, automobile headlights, and neon signs. CFLs and the other light bulbs listed above contain a small amount of mercury sealed within the glass tubing. CFLs also use the same technology as the linear fluorescent tubes we … Mercury is an essential component of all fluorescent light bulbs, and allows these bulbs to be energy-efficient light sources. Since their introduction in the 1970s as an improvement to mercury vapor and other HID (high-intensity discharge) lighting technologies, metal halide (MH) bulbs and fixtures have become one of the most popular choices for a wide range of commercial and industrial lighting applications. Depending on the type of ballast you use, the light may start immediately or take a few seconds to warm up to full brightness. The security light fixture has worked perfectly for several years. If the ignitor is bad, it won't send the high voltage pulse to the bulb, and it won't light. Remove the bulb by turning it in a clockwise direction. Mercury lamps, on the other hand, have been … If the bulb is black inside the glass or broken, you need to replace the sodium bulb. You should check all parts of the fixture, including the bulbs. Metal Halide ballast will run mercury vapor bulbs. According to the United States Government Printing Office, the Energy Policy Act of 2005 prohibited the manufacture and importation of mercury vapor light ballasts after January 1, 2008. This will indicate if the lamp is defective. I like mercury vapor better than HPS or MH, metal halide contains more mercury in it than mercury vapor and always tends to explode, also high pressure sodium creates an unpleasant orange haze at night (even full cutoff ones) and isn't very visable at night. Mercury vapor lamps are all-purpose bulbs. There’s not much away from them. “T” type light bulbs have a self-extinguishing feature that shuts off the light within 15 minutes after the outer bulb is broken. The voltage at the bulb falls wherever it will, usually somewhere between 25 and 100. Passed through it ) emits UV light reading is not between 20 and 50 kilohertz, UV.
