Lighting maintenance is easy; just replace burned-out lamps." 4.2 out of 5 stars 26. Such as: metal halide, pulse start, high pressure sodium capacitors and ignitors/starters. If you don't find any major differences between the two, you should energize the lighting system. Fig. Lithonia Lighting OFL 100M 120 LP BZM4 Premium Flood Light with 100-Watt Metal Halide. 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. Remember, though a ballast starts a lamp, this does not necessarily mean the ballast is functioning properly. Check for possibility that lamp is operated on ballast designed for higher... 2. The voltage on 50W through 400W lamps is at least 2500V; for the 1000W lamp, it's at least 3000V. They are heralded because of the quality of light they produce. Allow sufficient time for the lamps to cool down prior to restarting. You should replace a failed lamp immediately, as this situation can also cause starting circuit damage. 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. (See Appendix E.) A less common problem is failure of the ignitor. 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. Connect the meter's test leads to each terminal. You can divide the family of fluorescent lamps into the cathode preheat type and those requiring no cathode heating or starters. 120/240. This looseness at the ends allows lampholders to bend away from the center. Aerovox Lighting Capacitors, and HID Ignitors, for Metal Halide, Pulse Start and HPS Ballast Always in Stock, for Less!! Then, with the electrical power off, interchange the lamps. After all, you can stock fewer lamp types. Basic safety measures should always be taken when troubleshooting HID systems. If the reading is zero or a low resistance, the capacitor is shorted. Capacitor King has a full line of Aerovox lighting capacitors, and HID ignitors always in stock, always for less. Commonly, heat-caused deterioration will result in ballast winding or capacitor failure; open or shorted. Electronic Metal Halide Ballasts. Turn off the branch circuit power first; then discharge the capacitor by placing a screwdriver or other piece of metal across its terminals. Of course there's more to lighting maintenance than lamp replacement, particularly with discharge lamp systems. This latter symptom occurs when the lamp's cathode coating wears out. Unalux lamps operate on lagtype Mercury ballasts only. Taking both voltage measurements is a good indication of proper ballast operation. If an electronic ballast is being used, ensure the lamp is compatible. The family of arc discharge lamps includes fluorescent and high-intensity-discharge (HID) light sources. 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 that's the case, tighten it. Sometimes you'll find leads without the insulation. At the same time, you're applying a higher voltage (called the open-circuit voltage) across the lamp. An indication of the high-pressure-sodium (HPS) lamp's normal EOL is on/off cycling, since the aging lamp requires a higher voltage for operation than the ballast can supply. Keep in mind any wattage or ampere reading taken on the branch circuit will reflect this change of status condition. Replace lamp. Note: Mercury lamps will operate satisfactorily on ballasts designed for Metal Halide lamps of the same wattage. Your one-stop for legacy high-bay, parking, and roadway fixture ballasts. Sometimes, installers remove end plates and other supporting devices (needed to keep proper spacing) when installing fixtures in a row. Select a normal and abnormal fixture. Many lamp types currently offered, such as metal halide and high pressure sodium lamps, are physically interchangeable, but not electrically interchangeable. These ballasts meet CAN ICES-005 (A/B) / NMB-005 (A/B). If the spacing is too tight, the weight of the lamps will ride on the face of the base instead of the pins. 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. $55.27 $ 55. What basic safety precautions should be taken when troubleshooting HID ballasts? The ballast open-circuit voltage of these lamps is about three times the normal lamp operating supply voltage. Specialty varieties of Metal Halide lamps are used in sporting stadiums and industrial applications where light quality is important. ÈBÐAà t8BÐAà Ì+È+Ì+È+Ì+È+ì WÂ^ z%ì Wýñ觧§§§gO. You can check an HID ballast using a multimeter, similar to checking a fluorescent ballast. Reflecting back on the past year, we thought it would be worthwhile to revisit the 10 most popular photo galleries of 2016. Silver Series Ballast Troubleshooting Metal Halide and High Pressure Sodium lamps may require up to 15 minutes to restart after shutdown. What symptoms should you look for? 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. After they stabilize, observe the light fixtures. MS Excel Spreadsheets (XLS, XLSX) This section is dedicated to tools every electrical engineer can use in daily work. Wiring diagrams for Venture® standard metal halide ballast products are provided on this page. BLUE Metal Halide; E-Start Metal Halide; Standard Metal Halide; Dual Arc 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. An incorrect lamp-and-ballast combination will exhibit the same symptoms as a bad bulb. They have a re-strike time of 10 to 20 minutes. Presented in descending order, these galleries are ranked based on total website traffic over the last 12 months. Then, turn the tube 90 degrees. On the other hand, a series sequence ballast operates lamps in series (meaning if one lamp fails the other will fail or glow dimly). 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. Universal Cat. As such, verify the type of ballast before measuring heating voltage. Check the specifications on the ballast. These, in turn, relate to maintenance/troubleshooting needs. You need to clean fixture enclosures and reflectors to prevent needless loss of useful light output. Refer to the table in our catalog for the required ballast before referencing any diagram. The low-pressure-sodium (LPS) lamp has a U-shaped arc tube and a two-pin bayonet base. Short lamp life can result from ballast problems. This condition reduces the second lamp's life, causing a higher current to flow in the ballast. Operation in an overvoltage state increases wattage consumption and reduces the life of the ballast and lamp. These highly-efficient HID ballasts are also lightweight, small and have much better lumen maintenance, power regulation, and color consistency than any magnetic ballast. Fluorescent ballasts. 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). If lamps in a fixture fail to light, improper wiring could also be the cause. The data sheet tab has a list of the proper component sizes for most metal halide and High Pressure Sodium applications. If your ballast supports 600W Metal Halide, you need to get 600W Metal Halide bulbs. In some cases, you'll find two wires using one slot and, although there are two spring clips inside the socket, both wires are set under one. A traditional Probe Start Metal Halide system contains a ballast - which often includes a capacitor - and a lamp. Usually, a problem affects only a few fixtures in a total lighting layout. PowerVEG Family; Veg Formula; Flower Formula; Start-to-Finish Formula; Metal Halide. Can be used remotely with the Nanolux wireless control system. Includes 120V cord. 1. Thus, you must match a discharge lamp and ballast. 25% Plan to Finance Home Improvement Projects by Borrowing from Contractor, Emerald Cities-Boston Launches Contractor Academy. Step 2. 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. Here's how: With the lamp removed, use a true rms voltmeter to measure the voltage at the socket. What troubleshooting techniques can you use? One product has a positive end-of-life indicator, allowing you to identify and replace lamps near the end of their service life. The 10 Most Popular Photo Galleries of 2015, The 10 Most Popular Photo Galleries of 2014. Check voltage at ballast. The increased current, in turn, causes a rise in ballast temperature, reducing ballast life and possibly initiating smoke. Understanding the characteristics of fluorescent and HID lamps makes it easier to recognize problems and simplifies corrective maintenance. metal halide lamps comprise the majority of HID lighting applications. Assortment of metal halide ballast wiring diagram. Again, you should replace it. Generally, your troubleshooting task won't be this simple, since more than one factor usually contributes to component failure. Poor contact at the pins can result from improper lampholder spacing in the lengthwise direction, with the lamp end held too tightly or too loosely. Now, you can disconnect the capacitor from the circuit. Ceramic Metal Halide; Ceramic HPS; Double Ended Ceramic HPS; Ceramic HPS⢠Lamp Ballast Kit; T5 Fluorescent. A lead-lag ballast operates lamps in a parallel circuit; meaning if one lamp fails, the other should continue to operate properly. Turn off the branch circuit power first; then discharge the capacitor by placing a screwdriver or other piece of metal across its terminals. Again in 2016, conveying technical content through visual images in the form of photo galleries proved to be one of the largest website traffic generators among our readers. At this point the HPS lamp could 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. How to Troubleshoot a Metal Halide Light Fixture Step 1. Leaking compound (except for a small amount at the lead holes, which is normal), cracking or brittle insulation, and discoloration on the can are all indications of ballast approaching, or having reached, end of life.
