The family of arc discharge lamps includes fluorescent and high-intensity-discharge (HID) light sources. HID TROUBLESHOOTING GUIDE These suggestions are intended to serve as a ... Mercury and Metal Halide lamps at end of life tend to emit low light output along with ... the end of life. 4.2 out of 5 stars 26. If the "abnormal" appearance shifts to original "normal" system or fixture, the problem is in the lamp; not the ballast, fixture, or system power supply. Fluorescent lamps. With instant-start lamps, the two-lamp ballast circuit can be lead-lag or series sequence design. It's good practice to examine the wiring of the ballast leads to make sure it matches the diagram on the ballast label. They depend on the proper heating of cathodes to start and operate properly. Episode 27 - HID LAMPS AND BALLASTS - Metal Halide, High-Pressure Sodium, & Mercury Vapor July 22, 2019 in How Stuff Works , Materials , Lighting A lot of apprentices (and journeymen) have trouble understanding what makes HID lighting any different than regular lighting so troubleshooting them can be a bit confusing. While such bands may detract from the appearance of the lamp, moderately dark bands have no significance in regard to the life or performance of the lamp. All rights reserved. Then, turn the tube 90 degrees. Connect the meter's test leads to each terminal. The data sheet tab has a list of the proper component sizes for most metal halide and High Pressure Sodium applications. Lighting maintenance is easy; just replace burned-out lamps." It shows the components of the circuit as simplified forms, as well as the power as well as signal connections in between the gadgets. If the bulb is rated at 100 volts and … What troubleshooting techniques can you use? Basic safety measures should always be taken when troubleshooting HID systems. Here's how: With the lamp removed, use a true rms voltmeter to measure the voltage at the socket. This is a result of the lamp requiring more voltage from the ballast to stabilize and operate than the ballast can provide, thus the lamps cycle off and on. Lighting maintenance is easy; just replace burned-out lamps." (You can remove a vertically mounted lamp from the fixture using a lamp-changing pole.) This condition results from any one of the following: Corrosion or foreign material on base pins or holder contacts; Heavy premature end darkening (usually at only one end) is a good indication that one cathode is not properly heated and, therefore, the heater circuit is incomplete. 1, left, shows how to make voltage measurements on a two-lamp, series-type, rapid-start magnetic ballast. The lack of cathode heating voltage can result from a poor connection between lamp pins, lampholder contacts, or ballast leads and lampholder terminals. Advance electronic and magnetic HID ballasts are available to operate the wide variety of metal halide, high pressure sodium and low pressure sodium lamps available in today’s marketplace. Ceramic Metal Halide; Ceramic HPS; Double Ended Ceramic HPS; Ceramic HPS™ Lamp Ballast Kit; T5 Fluorescent. Step 3. At the same time, you're applying a higher voltage (called the open-circuit voltage) across the lamp. You also have to properly connect them, operating within specific limits. Of course there's more to lighting maintenance than lamp replacement, particularly with discharge lamp systems. A metal-halide lamp is an electrical lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides (compounds of metals with bromine or iodine).It is a type of high-intensity discharge (HID) gas discharge lamp. Reflecting back on the past year, we thought it would be worthwhile to revisit the 10 most popular photo galleries of 2016. After they stabilize, observe the light fixtures. Generally, your troubleshooting task won't be this simple, since more than one factor usually contributes to component failure. Instead of the usual on-again, off-again cycling, this version of the HPS lamp goes out without any cycling. Silver Series Ballast Troubleshooting Metal Halide and High Pressure Sodium lamps may require up to 15 minutes to restart after shutdown. This condition, known as lamp rectification, will cause a reduction in ballast life if it continues. The 10 Most Popular Photo Galleries of 2015, The 10 Most Popular Photo Galleries of 2014. They are heralded because of the quality of light they produce. The ballasts provide the open-circuit voltage, regulate the current (ampere flow) to the lamp, and maintain the necessary operating voltage. If you don't find any major differences between the two, you should energize the lighting system. Such as: metal halide, pulse start, high pressure sodium capacitors and ignitors/starters. These spreadsheets developed by enthusiasts will make your job much more easier, alowing you to shorten the time used for endless calculations of power cables, voltage drop, power factor, circuit breakers, capacitors, cable size, power transformers etc. All discharge lighting systems offer visual (and sometimes audible) clues when problems or failures exist. Turn off the branch circuit power first; then discharge the capacitor by placing a screwdriver or other piece of metal across its terminals. Understanding the characteristics of fluorescent and HID lamps makes it easier to recognize problems and simplifies corrective maintenance. Sometimes, installers remove end plates and other supporting devices (needed to keep proper spacing) when installing fixtures in a row. Because the size of the arc tube and mixture of materials in the tube differ for each HID lamp type, each has its own operating and end-of-life characteristics. Then, with the electrical power off, interchange the lamps. Occasionally, a pin will slide behind the clip instead of in front of it when you insert the lamp into the lampholders. The metal-halide (MH) lamp will drop in lumen output from 7% to 20% during the first 100 hrs of operation, depending upon lamp wattage. Instant-start and slimline lamps are two types that do not require the heating of cathodes, nor do they use starting aids. FREE Shipping by Amazon. Thus, you must match a discharge lamp and ballast. Lithonia Lighting OFL 100M 120 LP BZM4 Premium Flood Light with 100-Watt Metal Halide. You can check an HID ballast using a multimeter, similar to checking a fluorescent ballast. A note of caution: Hybrid magnetic ballasts (developed as a bridge technology between magnetic and fully solid-state electronic ballasts for 4-ft lamps) have components that cut off power to lamp cathode heaters after the lamp ignites, resulting in an additional 2W saving per standard lamp. Includes 120V cord. The electric arc of an HID lamp is much shorter and more intense in photometric brightness than a fluorescent arc. Atlas Lighting offers a wide selection of energy-saving LED, Fluorescent, and HID lighting products that are manufactured in our Burlington, NC facility, providing for extensive quality testing, faster delivery and quick turnaround on special build items. (See Appendix E.) If properly installed, HO and 1500mA lamps should have the boss or cover of their recessed double-contact ends out of sight. With the highest efficiency of HID light sources, its output is a monochromatic yellow, so all colors appear as shades of gray, brown, or black (except yellow objects). Presented in descending order, these galleries are ranked based on total website traffic over the last 12 months. Lamp wattages range from 20W to … You can use this latter type in an open fixture, where increased fixture efficiency and lower-maintenance costs are important. Hydro Crunch 630-Watt CMH Ceramic Metal Halide Hydro Crunch 630-Watt CMH Ceramic Metal Halide System is an all-inclusive commercial fixture with a high output and energy efficient system. Assortment of metal halide ballast wiring diagram. However, the lamp's ability to self-extinguish does not protect it against the danger of breakage. Make sure the tab inside the lamp socket makes proper contact with the base of the lamp. You should replace a failed lamp immediately, as this situation can also cause starting circuit damage. As such, verify the type of ballast before measuring heating voltage. When you energize a rapid-start lamp circuit, a low-voltage transformer in the ballast provides cathode heating. Metal-halide lamp (MH). Usually, a problem affects only a few fixtures in a total lighting layout. To run a test on the low voltage side of the metal halide ballast, you would begin by removing the nuts from the wires that come from the power feed side of the ballast. What symptoms should you look for? If the reading is zero or a very low resistance initially and the resistance slowly increases, the capacitor is good. A lead-lag ballast operates lamps in a parallel circuit; meaning if one lamp fails, the other should continue to operate properly. On the other hand, a series sequence ballast operates lamps in series (meaning if one lamp fails the other will fail or glow dimly). For commonly used 3/8-in.-thick twist-type lampholders, the back-to-back spacing of the lampholders should be 48 in., plus or minus 1/32 in. M100MLTLC3M500K 100 Watt 4-Tap 120-277V 60hz Magnetic MH Ballast Operates (1) 100W M-90, M-92, Or M-140 Lamp. Check for possibility of current or voltage... 3. 1. As such, you should install these lamps in an enclosed fixture that contains any glass, in case it shatters. Turn off the branch circuit power first; then discharge the capacitor by placing a screwdriver or other piece of metal across its terminals. Defective sockets and ballasts also need replacement. The ballast can no longer sustain an arc. A wiring diagram is a streamlined standard photographic representation of an electric circuit. Metal halide lamps do not require an ignitor to start, so the test for a failed ignitor for an HPS lamp is to screw in a metal halide bulb of the same wattage and see if it starts. You should not remove an HPS lamp from a lamp socket for more than a short period, unless you de-energize the circuit. Electronic metal halide ballasts are the best of all worlds, combining enormous versatility with seamless, fully integrated components. Metal Halide Metal halide lamps have an efficacy of 60 to 110 lumens per watt and have a warm-up time of 2 to 5 minutes. Specialty varieties of Metal Halide lamps are used in sporting stadiums and industrial applications where light quality is important. Sometimes you'll find leads without the insulation. These ballasts meet CAN ICES-005 (A/B) / NMB-005 (A/B). Refer to the table in our catalog for the required ballast before referencing any diagram. Normally at its EOL, an MH lamp won't start because the mix of materials in the arc tube changes, along with the electrical characteristics. Universal Cat. You can test the ballast capacitor with a suitable analog-type ohmmeter, set at a high resistance scale. Short lamp life can result from ballast problems. You can divide the family of fluorescent lamps into the cathode preheat type and those requiring no cathode heating or starters. Operating conditions, such as lamp burning position and normal variations in supply voltage or ballast characteristics, can affect lamp color and light output. If the reading is zero or a low resistance, the capacitor is shorted. Electronic Metal Halide Ballasts. This lamp version is also suitable for parking lot and garage lighting. Fluorescent ballasts. This latter symptom occurs when the lamp's cathode coating wears out. You can damage the starting circuit portion of the ballast, because the starting circuit will operate continuously with the lamp removed. Many lamp types currently offered, such as metal halide and high pressure sodium lamps, are physically interchangeable, but not electrically interchangeable. At that time, they usually show spiraling along the tube and occasional orange-colored flashes. Defective Ballast Step 2. One product has a positive end-of-life indicator, allowing you to identify and replace lamps near the end of their service life. Some ballasts support both Metal Halide and High Pressure Sodium, and will clearly state that on the box. The ballast data tables in our catalog indicate the page number and reference letter corresponding to the correct diagram for each ballast product. 945 Watt Ceramic Metal Halide Ballast 240V Combo (Bulb Included) 5.0 out of 5 stars 1. Excessive Current or Shorted Capacitor (s) $55.27 $ 55. Troubleshooting Procedures for … An HID lamp often is higher in wattage rating. They have a re-strike time of 10 to 20 minutes. It also may require a specific operating position; base-up, base-down, or base-horizontal. 99 Here, you should correct the wiring before you relamp the fixture. Normally, at its end-of-life, an MH lamp won't start because the mix of materials in the arc tube changes. Aerovox Lighting Capacitors, and HID Ignitors, for Metal Halide, Pulse Start and HPS Ballast Always in Stock, for Less!! How to Troubleshoot a Metal Halide Light Fixture Step 1. Most of the wires appear to be black and white, so the touch the probes of … Troubleshooting for Metal Halide Ballasts. Keep in mind any wattage or ampere reading taken on the branch circuit will reflect this change of status condition. Signs that a Metal Halide light bulb or ballast needs replaced: The lamp appears to be a different color, or are turning pink. This is one of the most serious maintenance problems in an HPS lighting system. Circuit Type HX-HPF Again, you should replace it. Of course there's more to lighting maintenance than lamp replacement, particularly with discharge lamp systems. If the outer bulb breaks or shatters in a safety line of MH lamps, power to the lamp interrupts. If the MH lamp starts and a new HPS lamp does not start, the ignitor probably needs to be replaced. When one lamp fails in a two-lamp series magnetic circuit, the second lamp may continue to operate, but at a lower brightness. During its burning hours, the wattage increases. ballast. This is a result of the lamp requiring more voltage from the ballast to stabilize and operate than the ballast can provide, thus the lamps cycle off and on. MS Excel Spreadsheets (XLS, XLSX) This section is dedicated to tools every electrical engineer can use in daily work. If the spacing is too tight, the weight of the lamps will ride on the face of the base instead of the pins. Electrical Product Listing: To Be or Not to Be? This isn't the same as gray or brownish bands that occur about 2 in. Now, you can disconnect the capacitor from the circuit. An incorrect lamp-and-ballast combination will exhibit the same symptoms as a bad bulb. HID lamps. Make sure you disconnect this starter circuit, since its high-voltage starting pulse can damage some multimeters. The figure, below, shows both rapid-start and instant-start types. You can classify most of these lamp types under the heading of rapid-start lamps. A shrouded arc tube line of MH lamps has a glass cylinder surrounding the arc tube to block any resulting glass fragments from hitting the outer glass bulb and causing it to shatter. A ballast changes the electrical characteristics of the power supply to those needed by the specific lamp for it to start reliably. Check the lamp -- it may have become loose in the socket. After all, you can stock fewer lamp types. Because of this relatively long life (coupled with a slow reduction in lumen output), you should replace these lamps well before they reach their average rated life. If the ohmmeter measures a high resistance, the capacitor is open and you should replace it. Info and repair tips, for troubleshooting. from the lamp base (with the edge of each band on the side nearer to the base being sharper). ÈBƒÐAà t8BƒÐAà Ì+È+Ì+È+Ì+È+애WÂ^ z%애Wžýñ菧‡§‡§‡§‡§‡gO. At this point the HPS lamp could Unfortunately, that's a common attitude of those holding the corporate purse strings. Your one-stop for legacy high-bay, parking, and roadway fixture ballasts. If an electronic ballast is being used, ensure the lamp is compatible. Check voltage at ballast. Replace lamp. If only one cathode gets the heating voltage, the lamp will fail to start or it will be slow starting. Capacitor King has a full line of Aerovox lighting capacitors, and HID ignitors always in stock, always for less. However, this attempt at saving money is short-lived. The cycling can damage or destroy the starting circuit and/or ballast. Usually the lamps will gain a pinkish hue when compared to other lamps in … If the lampholders are too far apart, the pins may ride on the edge of the lampholder rather than making contact along the full width of the metal piece. Most procedures will require that power be applied when electrical measurements are made. A traditional Probe Start Metal Halide system contains a ballast - which often includes a capacitor - and a lamp. Here's what you should look for in a lamp's appearance: After identifying any abnormal fixtures, you have to find out which component (lamp, ballast, fixture, or electrical supply) is the cause. Now, you can disconnect the capacitor from the circuit. Check the specifications on the ballast. Taking both voltage measurements is a good indication of proper ballast operation. 500W metal halide luminaires are impossible for traditional probe start metal halide ballasts to achieve so pulse start metal halide ballasts have been deemed the efficient replacement. Overwattage Operation Improper Ballasting If lamps in a fixture fail to light, improper wiring could also be the cause. Operation in an overvoltage state increases wattage consumption and reduces the life of the ballast and lamp. 2.3 Quartz Metal Halide (QMH) Metal Halide lamps have an efficacy of 80-115 lumens per watt and have a life between 10,000-20,000 hours. NO. But, how do you know what needs replacement? Fig. Don’t Let Arcing Ground Faults Sneak Up on You, Contact Voltage Testing: Tricks of the Trade, The 10 Most Popular Photo Galleries of 2016, The 10 Most Popular Photo Galleries of 2019, The 10 Most Popular Photo Galleries of 2018. These will start and operate even when one cathode is completely deactivated (which would be the end of normal life). If you wire a replacement ballast to a fixture, make sure all leads have a good electrical connection, especially if the lampholders have "pressure lock" or "quick-wire" terminals rather than screw terminals. If your ballast supports 1000W High Pressure Sodium, you need to get 1000W High Pressure Sodium bulbs. Note: Mercury lamps will operate satisfactorily on ballasts designed for Metal Halide lamps of the same wattage. Rapid-start (RS), high output (HO), and 1500mA T12 lamps (along with the preheat type requiring use of a starter device) all have similar characteristics. The increased current, in turn, causes a rise in ballast temperature, reducing ballast life and possibly initiating smoke. Select a normal and abnormal fixture. © 2020 Endeavor Business Media, LLC.
