You can use this latter type in an open fixture, where increased fixture efficiency and lower-maintenance costs are important. Replace lamp. 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. 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. You should replace inoperative instant-start lamps as soon as possible. One product has a positive end-of-life indicator, allowing you to identify and replace lamps near the end of their service life. 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. But, how do you know what needs replacement? Now, you can disconnect the capacitor from the circuit. 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. Operating conditions, such as lamp burning position and normal variations in supply voltage or ballast characteristics, can affect lamp color and light output of MH lamps. 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. This is one of the most serious maintenance problems in an HPS lighting system. What symptoms should you look for? At the same time, you're applying a higher voltage (called the open-circuit voltage) across the lamp. During its burning hours, the wattage increases. Lighting maintenance is easy; just replace burned-out lamps." Most of the wires appear to be black and white, so the touch the probes of â¦ 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. 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. Check voltage at ballast. These, in turn, relate to maintenance/troubleshooting needs. Defective sockets and ballasts also need replacement. Nanolux now offers square wave technology in its 315W Ceramic Metal Halide Ballast. At this point the HPS lamp could Reflecting back on the past year, we thought it would be worthwhile to revisit the 10 most popular photo galleries of 2016. BREAKER If lamp will not start, reset the breaker by pressing the white button located on the input side of the ballast. 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. Aerovox Lighting Capacitors, and HID Ignitors, for Metal Halide, Pulse Start and HPS Ballast Always in Stock, for Less!! Both the 1000W and 400W lamps, when burned vertically, have a passive EOL. If you don't meet all of these conditions, the light source won't work properly. If your ballast supports 600W Metal Halide, you need to get 600W Metal Halide bulbs. Some recent developments in HPS lamp technology aim at eliminating the end-of-life cycling, especially in highway and street lighting. 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. Signs that a Metal Halide light bulb or ballast needs replaced: The lamp appears to be a different color, or are turning pink. An MH lamp, designed for a particular operational position, can provide 10% to 15% more light and last as much as 60% longer than the equivalent universal position lamp. What basic safety precautions should be taken when troubleshooting HID ballasts? M100MLTLC3M500K 100 Watt 4-Tap 120-277V 60hz Magnetic MH Ballast Operates (1) 100W M-90, M-92, Or M-140 Lamp. Troubleshooting for Metal Halide Ballasts. 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 todayâs marketplace. The cycling can damage or destroy the starting circuit and/or ballast. How to Troubleshoot a Metal Halide Light Fixture Step 1. Metal-halide lamp (MH). This latter symptom occurs when the lamp's cathode coating wears out. Ceramic Metal Halide; Ceramic HPS; Double Ended Ceramic HPS; Ceramic HPSâ¢ Lamp Ballast Kit; T5 Fluorescent. Using a universal burning MH lamp (instead of the original position-specific lamp) when relamping a fixture may seem like a good economic decision. PowerVEG Family; Veg Formula; Flower Formula; Start-to-Finish Formula; Metal Halide. Consult the manufacturer if necessary. A lead-lag ballast operates lamps in a parallel circuit; meaning if one lamp fails, the other should continue to operate properly. ballast. $55.27 $ 55. Allow sufficient time for the lamps to cool down prior to restarting. Usually, a problem affects only a few fixtures in a total lighting layout. 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. Most procedures will require that power be applied when electrical measurements are made. You can divide the family of fluorescent lamps into the cathode preheat type and those requiring no cathode heating or starters. from the lamp base (with the edge of each band on the side nearer to the base being sharper). On the other hand, a series sequence ballast operates lamps in series (meaning if one lamp fails the other will fail or glow dimly). 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. Again, you should replace it. Wiring diagrams for Venture® standard metal halide ballast products are provided on this page. Basic safety measures should always be taken when troubleshooting HID systems. Occasionally, a pin will slide behind the clip instead of in front of it when you insert the lamp into the lampholders. Refer to the table in our catalog for the required ballast before referencing any diagram. ÈBÐAà t8BÐAà Ì+È+Ì+È+Ì+È+ì WÂ^ z%ì Wýñè§§§§§gO. Your one-stop for legacy high-bay, parking, and roadway fixture ballasts. Here, you should correct the wiring before you relamp the fixture. In the useful information section is information for troubleshooting capacitors,HID ballast transformers, ignitors, lamps, sockets and more. This lamp version is also suitable for parking lot and garage lighting. BLUE Metal Halide; E-Start Metal Halide; Standard Metal Halide; Dual Arc You can test the ballast capacitor with a suitable analog-type ohmmeter, set at a high resistance scale. Connect the meter's test leads to each terminal. Generally, your troubleshooting task won't be this simple, since more than one factor usually contributes to component failure. Discharge lamps usually operate with a ballast specifically designed to provide the proper starting and operating voltage for the lamp. HID ballasts. Excessive Current or Shorted Capacitor (s) When one lamp fails in a two-lamp series magnetic circuit, the second lamp may continue to operate, but at a lower brightness. The 1000W, 400W lamps, and all other wattages, when burned in other positions, can fail in a way that causes the outer bulb to shatter. 4.2 out of 5 stars 26. An electric arc struck between two main electrodes or cathodes produces light in these lamps, which are usually at opposite ends of the lamp. After they stabilize, observe the light fixtures. Unfortunately, that's a common attitude of those holding the corporate purse strings. This looseness at the ends allows lampholders to bend away from the center. Info and repair tips, for troubleshooting. 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. Short lamp life can result from ballast problems. Select a normal and abnormal fixture. Symptoms of lighting system problems. All rights reserved. Also, make sure to check the voltage at the point of connection to the electrical distribution system. Look for broken tubes or loose metal parts. You should replace flickering instant-start lamps that show heavy end blackening. If that's the case, tighten it. However, the lamp's ability to self-extinguish does not protect it against the danger of breakage. 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. Defective Ballast This isn't the same as gray or brownish bands that occur about 2 in. If the reading is zero or a very low resistance initially and the resistance slowly increases, the capacitor is good. They have a re-strike time of 10 to 20 minutes. This voltage beginsarc conduction in the lamp. What troubleshooting techniques can you use? During operation, an HID ballast produces heat and usually receives some heat from the lamp it serves. Turn off the branch circuit power first; then discharge the capacitor by placing a screwdriver or other piece of metal across its terminals. 1, left, shows how to make voltage measurements on a two-lamp, series-type, rapid-start magnetic ballast. metal halide lamps comprise the majority of HID lighting applications. The increased current, in turn, causes a rise in ballast temperature, reducing ballast life and possibly initiating smoke. You can damage the starting circuit portion of the ballast, because the starting circuit will operate continuously with the lamp removed. 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. The voltage on 50W through 400W lamps is at least 2500V; for the 1000W lamp, it's at least 3000V.

If the MH lamp starts and a new HPS lamp does not start, the ignitor probably needs to be replaced. You should replace a failed lamp immediately, as this situation can also cause starting circuit damage. Step 2. Instead of the usual on-again, off-again cycling, this version of the HPS lamp goes out without any cycling. How to test the low voltage side of the ballast. If an electronic ballast is being used, ensure the lamp is compatible. These will start and operate even when one cathode is completely deactivated (which would be the end of normal life). The low-pressure-sodium (LPS) lamp has a U-shaped arc tube and a two-pin bayonet base. 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. Commonly, heat-caused deterioration will result in ballast winding or capacitor failure; open or shorted. This is known as color shift, a natural effect of Metal Halide over long periods of operation. An HID lamp often is higher in wattage rating. Note: Mercury lamps will operate satisfactorily on ballasts designed for Metal Halide lamps of the same wattage. Check the specifications on the ballast. Now, you can disconnect the capacitor from the circuit. 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. Normally, at its end-of-life, an MH lamp won't start because the mix of materials in the arc tube changes. Assortment of metal halide ballast wiring diagram. A wiring diagram is a streamlined standard photographic representation of an electric circuit. If properly installed, HO and 1500mA lamps should have the boss or cover of their recessed double-contact ends out of sight. 945 Watt Ceramic Metal Halide Ballast 240V Combo (Bulb Included) 5.0 out of 5 stars 1. This condition reduces the second lamp's life, causing a higher current to flow in the ballast. They depend on the proper heating of cathodes to start and operate properly. Instant-start and slimline lamps are two types that do not require the heating of cathodes, nor do they use starting aids. The family of arc discharge lamps includes fluorescent and high-intensity-discharge (HID) light sources.

Ballast troubleshooting. 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. These ballasts meet CAN ICES-005 (A/B) / NMB-005 (A/B). 1. When installing lamps with exposed bi-pins, make sure the positioning guide (an embossed mark on the metal end cap) is opposite the entrance slot of the lampholder before inserting. Make sure the tab inside the lamp socket makes proper contact with the base of the lamp. TROUBLESHOOTING GUIDE Follow the troubleshooting tips below. All discharge lighting systems offer visual (and sometimes audible) clues when problems or failures exist. 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. Includes 120V cord. Check for possibility that lamp is operated on ballast designed for higher... 2. It's difficult to measure the output voltage of fluorescent ballasts in a luminaire because the primary circuit of the ballast is automatically disconnected when you remove an instant-start lamp. Circuit Type HX-HPF You need to clean fixture enclosures and reflectors to prevent needless loss of useful light output. © 2020 Endeavor Business Media, LLC. It's good practice to examine the wiring of the ballast leads to make sure it matches the diagram on the ballast label. If the reading is zero or a low resistance, the capacitor is shorted. Understanding the characteristics of fluorescent and HID lamps makes it easier to recognize problems and simplifies corrective maintenance. 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. As such, you should install these lamps in an enclosed fixture that contains any glass, in case it shatters. Many lamp types currently offered, such as metal halide and high pressure sodium lamps, are physically interchangeable, but not electrically interchangeable. 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. You should take specific safety precautions when working on an HPS ballast. You also have to properly connect them, operating within specific limits. With instant-start lamps, the two-lamp ballast circuit can be lead-lag or series sequence design. It shows the components of the circuit as simplified forms, as well as the power as well as signal connections in between the gadgets. 7821 WOODLAND CENTER BLVD TAMPA, FL 33614 PH: 813.288.8006 FX: 813.288.8105 WWW.HATCHLIGHTING.COM BALLASTS, DRIVERS, TRANSFORMERS & LAMPS FOR ALL LIGHTING APPLICATIONS. If the ohmmeter measures a high resistance, the capacitor is open and you should replace it. The ballast can no longer sustain an arc. Lamp wattages range from 20W to â¦ If your ballast supports 1000W High Pressure Sodium, you need to get 1000W High Pressure Sodium bulbs. The figure, below, shows both rapid-start and instant-start types. Such as: metal halide, pulse start, high pressure sodium capacitors and ignitors/starters. This type of lamp has a specific warm-up time when you first energize it. For that reason, its insulation material can break down and cause a short in the core/coil windings. For example, a 180W LPS lamp consumes 247W at 20,000 hrs.
