For example, a round-shaped fluorescent bulb is connected to a socket along with the ballast. Go to Membership and Subscriptions to see whats available. The typical . The light bulbs have a negative differential resistance, which makes them fragile when it comes to current load. For international or industrial use, 347-480V ballasts are available. How Do You Test A Metal Halide Ballast? If you can follow the process correctly, you will not need an electrician for this simple testing job. Replace the device if you dont get the required results. T8 tubes have a diameter of 1-inch, while T12 tubes have a diameter of 1 1/2 inches. If you see any form of oil or liquid on your ballast, then its internal seal has been damaged by excessive heat and the whole unit needs to be changed. << /Length 5 0 R /Filter /FlateDecode >> Turn off the breaker supplying the lamp and tighten the connections on the ballast with a screwdriver. This will reveal a lot about your current fluorescent tube, and it will usually tell you whether the bulb is T8 or T12. Uncheck the Allow Handoff setting in System Preferences > General on your Mac. Once the ballast is physically fit, go for the resistance and voltage test using a multimeter. However, all these things are the ways to check a ballast physically. In both cases, voltage readings should match the output specified on the label. If that's the case, tighten it. If you get any result other than these, like a low resistance reading, then it is faulty and needs to be changed. He is the host of the Electro University YouTube channel, which has thousands of subscribers. When the lamp is inactive, the mercury and metal halide salts are condensed inside the inner arc tube. This rating is traditionally used to indicate that 50% of the lamps will fail, but when it comes to maintenance, this is the DO NOT EXCEED period of all lamps. To test an electronic ballast, you will need a DC voltmeter and an ammeter. Check socket for loose contacts, poor connections, or broken wiring. Identify any leaky areas. Situation: I inherited 3 100W overhead fishing lights (metal halide with pulse start) and one of them died circuit doesn't have a capacitor, but has ignitor; bulb is marked with M90/E; fixture uses 120V AC, but multimeter shows 240V at the bulb base by moving parts (ballast, bulb and ignitor) to other fixtures I figured that ignitor is not working Some probe start lamps do not have a problem operating on pulse start ballasts.
