how to tell if a mercury vapor bulb is bad

Incorrect bulb usage can result in damage to the fixture or the bulb's exploding. Pull the bulb straight out of the fixture. 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*. Mercury short-arc lamps are used for special applications, such as search lights, specialized medical equipment, photochemistry, UV curing, and spectroscopy. ... How do I know if my fluorescent starter is bad? By this point, most lamps have lost at least 40% of their original light output. You should now test the mercury-vapor lamp. UV exposure at this level can cause eye and skin burns, blurred or double vision, headaches, and nausea. This will tell you whether the lamp and the capacitor are good. Mercury vapor lamps are all-purpose bulbs. Cover the sensor completely with a dark cloth so that no light can get to any part of the sensor. The best fluorescent on the market, the Reptisun, puts out 66. However, if the outer bulb breaks, and the inner tube continues to produce unshielded light, intense UV radiation is emitted. 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. Once a new lamp is installed, the metal halide bulb will light and come up to full brightness. Philips Mercury Vapor lamps last at least 24,000 hours. The difference in UVB is enormous. Pros: The best Mercury Vapor Bulb on the market, the Megaray, puts out 400 microwatts of UVB. However, mercury-vapor lamps are falling out of favor and being replaced by sodium-vapor and metal-halide lamps. 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. Mercury Vapor bulbs have an arc tube that contains a minute amount of liquid mercury under pressure that vaporizes with an electrical charge. The mercury vapor lamp is a high intensity discharge lamp. 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. 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 . Examine the bulb for signs it has burned out. The bulb is filled with argon and mercury vapor at low pressure. It also lasts a year instead of 6 months. The mercury vapor lamp is a negative resistance device. 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. 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. Added to this is a small amount of mercury. 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. 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.
