Despite the mandate, there are plenty of old outdoor mercury vapor lights still in use in the United States. Mercury is a naturally occurring metal that is in many everyday products, albeit in tiny amounts. High pressure sodium, and mercury vapor. When a bulb breaks in your home, some of this mercury may be released as mercury vapor. As a metal halide lamp ages, it will require a greater load to maintain illumination. Mercury Vapor bulbs have an arc tube that contains a minute amount of liquid mercury under pressure that vaporizes with an electrical charge. When the mixture is energized (excited) it creates a glowing plasma of electrons that pass through the mercury vapor. Why is It Important to Clean Up a Broken CFL Properly? Mercury short-arc bulbs; and; Neon bulbs. 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. As with fluorescent lights, mercury vapor lamps require a ballast to supply the proper voltage and regulate the current to the electrodes. “T” type light bulbs have a self-extinguishing feature that shuts off the light within 15 minutes after the outer bulb is broken. If the bulb is black inside the glass or broken, you need to replace the sodium bulb. They either stick on or they stay off. 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. CFLs and the other light bulbs listed above contain a small amount of mercury sealed within the glass tubing. 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 . Take one or two bulbs out of the fixture if it is a multi-bulb light. The mercury vapor lamp is a negative resistance device. Providing 160 Watts of UVB, this bulb is ideal for Buyer’s Tip: Like this bulb but need something less strong? Incorrect bulb usage can result in damage to the fixture or the bulb's exploding. Return fluorescent bulbs to the socket if they were removed to reach the starter. Additionally, their wavelengths are typically shorter than sunlight, and that can potentially cause cell damage & photo-kerato-conjunctivitis. However, while you should take precautions to clean up mercury vapor bulbs carefully, the actual threat in domestic settings in minimal. But it has to be designed, too. If you have a liquid-in-glass thermometer, it is important to be able to tell if it contains mercury. You should check all parts of the fixture, including the bulbs. Since the light emitted by a mercury-vapor light has a blue tone, this needs to be accounted for, or color- … This will tell you whether the lamp and the capacitor are good. 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. The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger glass bulb. Mercury is an essential ingredient in all energy efficient lighting technologies, including compact fluorescent bulbs. 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. 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. They typically have spikes through the UV spectrum; so although not necessarily a health risk, it is not as consistent as other bulbs. There are two types of mercury vapor light bulbs sold in the U.S. Test the ballast's voltage with a multimeter. The ballast of a light fixture ignites the vapor inside the bulb. Their Venture ballasts (BV-V90D6112K) are $37. By this point, most lamps have lost at least 40% of their original light output. I've NEVER had a bad bulb come on and off. Mercury lamps, on the other hand, have been … This is why the CFL works. Depending on the type of ballast you use, the light may start immediately or take a few seconds to warm up to full brightness. Despite the mandate, there are plenty of old outdoor mercury vapor lights still in use in the United States. 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. 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. However, if the outer bulb breaks, and the inner tube continues to produce unshielded light, intense UV radiation is emitted. 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. 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, : 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. Mercury vapor lamps are all-purpose bulbs. This energy (UV light) is then absorbed by a thin coating of white phosphor on the inside of the bulb. ... How do I know if my fluorescent starter is bad? I have a great mercury vapor bulb that I use for my bearded dragon. The bulb is filled with argon and mercury vapor at low pressure. This ban is ridiculous and no one in their right minds would of ever thought about passing this law in the first place. “You’re talking u… 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. If you’re still unsure your ballast has bit the dust, then … 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. Mercury vapor lamps are gas discharge lamps that uses an electric arc through vaporized mercury to produce light. The light fixture should turn on. You can't just slap a random incandescent together with a random mercury-argon bulb. If the liquid is silver in color it might be mercury. 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. It uses an arc through vaporized mercury in a high pressure tube to create very bright light directly from it's own arc. Adjust the multimeter to measure frequency and replace the ballast if the reading is not between 20 and 50 kilohertz. The voltage should read 15 VAC, but it should ramp up to 130VAC within 5 to 10 minutes. Fluorescent tubes and compact fluorescent light bulbs (CFLs) can release sufficient mercury vapor to cause poisoning. Checking a common light bulb using a multimeter on the ohm scale. 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. For more information, see Ultraviolet Radiation Burns from High Intensity Metal Halide and Mercury Vapor Lighting Remain a Public Health Concern (December 6, 2005). Use UVB Mercury Vapor basking lights with caution. Mercury short-arc bulbs; and; Neon bulbs. It generates both heat and a good level of UVB and at last a lot longer than a straight UVB bulb of any sort. Testing to see if it is good or bad. CFLs and the other light bulbs listed above contain a small amount of mercury sealed within the glass tubing. You should now test the mercury-vapor lamp. CFLs also use the same technology as the linear fluorescent tubes we … I've also never had a bad photocell come on and off. Cons: It needs to be about a foot away from your Beardie, so you may have to get a stand. A fluorescent light bulb (also referred to as a "lamp") is a gas-discharge bulb that uses electricity to excite mercury vapor. Mercury vapor lights consist of a gas-filled glass chamber, protective glass bulb, electrodes and a ballast. The best fluorescent on the market, the Reptisun, puts out 66. CFLs also use the same technology as the linear fluorescent tubes we … 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. ��ëí¢ÙæY@åüşÀU§HBíÏ¿úó£‹Ö*š)%@‚:D±H„PP˜ƒºa•r ®ıNY¿IDJ€! As they strike mercury atoms, a mercury electron is liberated at a frequency representative of mercury’s spectral line, which is 253.7nm. Tungsten (except for its long time constant) is a good fit for these applications. 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. Breathing elemental mercury into your lungs is generally more dangerous than if you ate the mercury or absorbed it through your skin. They give off heat, visible light and UVB rays. It has a bluish green appearance and features a low initial cost. Using a mercury vapor lamp with a ballast that was made for a higher wattage bulb might damage it or cause it to explode. The protective bulb filters out harmful ultraviolet light and keeps the mercury gas contained if the inner chamber breaks. *,Eš Úè…}ÑÕÅ�.»ëxœ³½±ÕÕ~À}î,ğWõ­o´ÂFeØH.’lU`‡7�²¾6. This will tell you whether the lamp and the capacitor are good. 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. If your pet doesn’t really bask, he may not actually get enough UVB from one of these. Attach the multimeter's leads to the sockets at the ends of the ballast. 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. A mercury HID bulb exhibits a blackening at the end of the arc tube. Added to this is a small amount of mercury. However, this is not the correct repair. This is enclosed by an outer glass bulb that filters out harmful short-wavelength ultraviolet (UV) radiation. The first course of action is to simply change the bulb. The difference in UVB is enormous. Compact fluorescent lamps (CFLs), which are popular in many households, contain 4 mg of mercury on average. This will indicate if the lamp is defective. The excited mercury atoms produce short-wave ultraviolet light that causes a phosphor to fluoresce, producing visible light. But clean energy expert John Rogers is here to ease your mind. Likewise skin aborption of liquid mercury is insignificant compared to inhaling mercury vapor. Should I change the light bulb, sensor or the whole light? Cover the sensor completely with a dark cloth so that no light can get to any part of the sensor. Examine the bulb for signs it has burned out. However, mercury-vapor lamps are falling out of favor and being replaced by sodium-vapor and metal-halide lamps. Under normal operating conditions mercury vapor lamps provide efficient, long-lasting sources of light. Mercury short-arc lamps are used for special applications, such as search lights, specialized medical equipment, photochemistry, UV curing, and spectroscopy. A few simple steps can help. Yes, I know that they're not 'regular' light bulbs. Philips Mercury Vapor lamps last at least 24,000 hours. 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. The lamp needs to … 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. The bulb is comprised of an inner tube, called the arc tube, and an outer jacket (or bulb). Such a fixture will have the matching ballast in it. “R” type light bulbs do not have a self-extinguishing feature. There’s not much away from them. Observe the interior gas tube for any signs of discoloration. 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. However, if the outer bulb breaks, and the inner tube continues to produce unshielded light, intense UV radiation is emitted. 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. Under normal operating conditions mercury vapor lamps provide efficient, long-lasting sources of light. You can find ballast for $30 to $40 on the internet. High pressure sodium, and mercury vapor. 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. 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. Identify what type of lamps you have. Once a new lamp is installed, the metal halide bulb will light and come up to full brightness. 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. 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. If the ignitor is bad, it won't send the high voltage pulse to the bulb, and it won't light. These lights are typically controlled by a photocell that turns the light on at dusk. 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. 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. Before sharing sensitive information, make sure you're on a federal government site. 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. The site is secure. Compact fluorescent bulbs save energy but they also contain mercury, a toxic metal. Cover the sensor completely with a dark cloth so that no light can get to any part of the sensor. UV exposure at this level can cause eye and skin burns, blurred or double vision, headaches, and nausea. Needless to say, you don't want to put any other kind of bulb there. Your HPS (High Pressure Sodium) lamp has a ballast made of a hefty transformer, capacitor and "ignitor circuit". The ballast sends electrical power to the electrodes, which excites the gas and makes it glow. The bulbs have an inner quartz tube containing the mercury vapor discharge. It also lasts a year instead of 6 months. If inhaled in vapor form it is readly absorbed into the blood 80% absorption. The heavy duty transformer or ballast is also long lived if the bulbs are changed out before they burn out. So they give off both heat and the necessary UV rays, making it a two-in-one package. Mercury is an essential component of all fluorescent light bulbs, and allows these bulbs to be energy-efficient light sources. 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. 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 . Strip lights contain low pressure mercury vapor which when iodized (electric current passed through it) emits UV light. 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. Mercury Vapor Bulbs. 99 They provide both UVB and UVB rays. Spilled mercury has a characteristic appearance. On the flip side, mercury vapor bulbs are more expensive, stronger, and tend to last longer. 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 sensor has to be in its socket to test it as it needs power to it to operate. If so, it sounds like you’re in need of a great mercury vapor bulb for your bearded dragon! 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. If the reading is not between five and nine volts, replace the ballast. It is slightly more expensive, but some advantages make it worth using: Mercury vapour bulbs last longer than heat bulbs and fluorescent bulbs. 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. To minimize exposure to mercury vapor, … It uses an arc through vaporized mercury in a high pressure tube to create very bright light directly from it's own arc. That said, they’re best used as basking bulbs, because the heat and UV rays are highest right under them. With the small arc size and high power, the arc is extremely intense. With headlines circulatingabout mercury in CFLs, the initial freak-out moment after breaking a bulb is understandable. If the light comes on and doesn't flicker continuously, the starter was the problem. The advantage is that it produces a bright white light, with relatively long life. 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. Mercury Vapor Bulbs: This option might be better than the other two. Metal Halide ballast will run mercury vapor bulbs. Top of page. Mercury-vapor lamps were the first commercially available HID lamps. If the ballast is bad, then the needle won’t move. My dragon is in brumation right now, and his fixture is available. Pros: The best Mercury Vapor Bulb on the market, the Megaray, puts out 400 microwatts of UVB. Plug it into an outlet and take measurements of the voltage that goes between the capacitor lead that is black and the COM. 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. UV exposure at this level can cause eye and skin burns, blurred or double vision, headaches, and nausea. I ordered from a company in Texas to make sure that I received them by Memorial Day weekend. In industrial settings, things are a little trickier. 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. Top of page. Testing the Mercury Vapor Lamp. The security light fixture has worked perfectly for several years. 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. A typical fluorescent lamp is composed of a phosphor coated glass tube with electrodes located at either end. The outer bulb may be clear or coated with a phosphor. If you’re using a digital multimeter, often the digital readout will possibly list a “1” when it doesn’t find a measurable resistance. Ballast is necessary to run the 175w mercury vapor bulbs that are used for underwater lights. The dominant emission (>90%) from these lamps is UV-C energy. The mercury vapor lamp is a high intensity discharge lamp. This filament is the weak point in the bulb. Check whether it still hums. Metal halide Mercury Vapor Bulbs will supply UVA, UVB, and heat for your bearded dragon… making them a kind of “all in one” option. This is different from fluorescents which use the mercury vapor arc to create a weaker light … Plug it into an outlet and take measurements of the voltage that goes between the capacitor lead that is black and the COM. Compact fluorescent lamps (CFLs), which are popular in many households, contain 4 mg of mercury on average. The outer bulb can also be coated with phosphor to diffuse the light or change its color. 70 1) Self Ballasted Mercury Vapor (SBMV bulbs) bulbs have a filament inside that works as a ballast. The mercury vapor lamp works by creating an electric current to mercury vapor within a sealed glass jacket. Remove the bulb by turning it in a clockwise direction. Identify what type of lamps you have. The .gov means it’s official.Federal government websites often end in .gov or .mil. (These are conservative estimates based on comparison to a bulb with 5 mg of mercury.) You should now test the mercury-vapor lamp. The mercury vapor lamp is a high intensity discharge lamp. A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. Check out their 100 Watt version here! Mercury Vapor Bulbs. Once inhaled, the mercury vapor … Pull the bulb straight out of the fixture. The voltage at the bulb falls wherever it will, usually somewhere between 25 and 100. Why is It Important to Clean Up a Broken CFL Properly? Wattage can range from under a hundred watts to a few kilowatts. 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*. Use UVB Mercury Vapor basking lights with caution. (These are conservative estimates based on comparison to a bulb with 5 mg of mercury.) Conversely, mercury-vapor lamps have a glow-phase and a glow-to-arc phase transition which has a very high "negative resistance" response. Mercury Vapor Bulbs also tend to be more expensive, longer lasting, and significantly stronger than fluorescent UVB bulbs. This means its resistance decreases as the current through the tube increases. The https:// ensures that you are connecting to the official website and that any information you provide is encrypted and transmitted securely. Using too small of a ballast will result in lower light output and can shorten the life of the bulb. 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. Turn on the switch. Originally they produced a bluish-green light, but more recent versions can produce light with a less pronounced color tint. If the liquid is not silver in color, it does not contain mercury. Confirmed that this 60 W germicidal bulb is fake (no UV emissions). 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. When a bulb breaks in your home, some of this mercury may be released as mercury vapor. I've been in maintenance for many years myself, and I've rebuilt more of these than I can count. 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.
